A portion of a plate with continental crust composing its uppermost layer is thicker than one bearing ____________________ crust
Answer:
A portion of a plate with continental crust composing its uppermost layer is thicker than one bearing Oceanic crust
Explanation:
The continental crust which is the uppermost layer of the lithospheric plate is thicker and less dense than the oceanic crust because of the constituent that makes up the crust. The continental crust is mainly compose of granitic rocks.
The oceanic crust are more dense and thinner than the continental crust . The oceanic crust is mainly composed of Mafic rocks like the basaltic rocks . And the high density nature of the oceanic crust contribute to it less active nature if it collides with the continental crust . when it collides with the continental crust it tends to subduct.
The oceanic crust has a thickness of about 70 km while the thickness of the continental crust ranges from 125 km to 250 km . Rocks found in the continental crust are usually more older than the rocks found in the oceanic crust because in the oceanic crust newer crust are been formed around the oceanic ridges while the older rocks are subducted in trenches.
Which of the following is NOT an ecosystem service provided by pristine forests? a. prevention of soil erosion b. removal of air pollution c. moderation of climate d. land for agriculture
Answer:
d
Explanation:
Pristine forests do not provide the ecosystem service of land for agriculture because converting forests into farmland requires anthropogenic activities, which result in environmental issues like deforestation and climate change.
Explanation:The ecosystem service among the options that is NOT provided by pristine forests is option d. land for agriculture. Pristine forests, by their very definition, are untouched and unspoiled by human activities, including agriculture. While forests provide critical ecosystem services like prevention of soil erosion (option a), removal of air pollution (option b), and moderation of climate (option c), they do not naturally provide land for agricultural use. Any conversion of forest land into agricultural land typically comes with negative impacts such as deforestation, which leads to a reduction in habitats for numerous species, buildup of greenhouse gases, soil erosion, and a disrupted local climate.

a. neritic siliceous sediment deposits.
b. neritic coarse lithogenous sediment deposits.
c. abyssal clay deposits.
d. manganese nodule deposits.
e. pelagic biogenous calcareous deposits.
Answer: b. neritic coarse lithogenous sediment deposits.
Explanation:
Sediments are formed from different sources, both terrestrial and aquatic and are deposited by the movement of water, glaciers and wind. The type of deposits formed from erosion of terrestrial materials are known as Lithogenous sediments. The range in size from fine to coarse particles.
Neritic and Pelagic refer to different depths in an ocean. While neritic refers to the area close to the coast, Pelagic refers to the the deep ocean. Neritic, coarse lithogenous deposits are found on shallow ocean floor s as well as along the coast, and make the thickest deposits worldwide.
This is a galaxy with a characteristic pinwheel shape with a flat disk, central bulge, and graceful arms containing regions where young stars form ___.
Answer:
A spiral galaxy.
Explanation:
This is a class of galaxy described in 1936 by the American astronomer Edwin Hubble.
The central bulge is characteristic of this type of galaxies, where the major concentration of stars resides. The "arms" are very bright and are full of young, blue stars.
The pinwheel shape is why we can easily recognize them from the earth. Astronomers think that more than 60% of the galaxies in the universe are spiral-like.

Answer:
YES, the positive feedback leads to the instability and the negative feedback leads to the stability.
Explanation:
The melting of the glacier ice is an example of the negative feedback as it being a balance in the amount of the ice and the temperature extremes and therefore is a proper way to check the ice cover and thus he arctic ocean will be balanced by the absorption of the sun heat and the leads to the reduction in the temperatures in the nearby lands. And it's a natural cyclic system of the earth.41. Magma that cools underground forms ___________.

All continents fit together with the least number of overlaps and gaps when the continents are matched along:________
A) contours at around 2,000 meters depth.
B) current shorelines.
C) edge of the continental shelf.
D) edges of the deep sea floor.
E) oceanic trenches in subduction zones.
Answer:
A) contours at around 2,000 meters depth.
Explanation:
As the contours of the world when measured from a 2000 meters depth shows us the same orientation and fitting f the continental shelf sand the plates as the lines joined the place as they are then overlapped and hence are connected by the values that are assigned to them.Final answer:
All continents fit together with the least number of overlaps and gaps along the edge of the continental shelf, which is the underwater extension of the continent before the continental slope.
Explanation:
The continental shelf is the ocean floor nearest the edges of continents, characterized by a gentle slope and shallow waters, usually extending about 100 to 200 kilometers from the shore up to the shelf break. This feature represents where the continental crust continues underwater before reaching the steep continental slope.
While options such as contours at around 2,000 meters depth, current shorelines, edges of the deep sea floor, and oceanic trenches may seem plausible, they do not represent the precise match points that existed when the continents were once connected. Oceanic-continental convergence, which shapes features like trenches and submarine canyons, occurs at plate boundaries but is not where continents would seamlessly connect.
From the information given below, which city has the highest relative humidity?
Urbana, IL: T = 52F, Td = 32F St. Louis, MO: T = 69F, Td = 46F Milwaukee, WI: T = 22F, Td = 21F (difference) Austin, TX: T = 90F, Td = 40F
a.Urbana
b.St. Louis
c.Milwaukee
d.Austin
Answer: c. Milwaukee
Explanation:
The warmer the air gets, the higher its capacity for water vapor. Thus, the relative humidity would increase as the dew point temperature decreases and vice versa. The relative humidity is usually highest at sunrise at the point when the overnight low temperature is usually close to the dew point.
Since Milwaukee has the lowest Td = 21°F and its R.H = 51.358, a value higher than the rest since the rest have negative values.
Final answer:
Milwaukee, WI, has the smallest difference between the temperature and dew point, indicating it has the highest relative humidity among the listed cities.
Explanation:
From the given data, the city with the highest relative humidity must be determined by comparing the temperature (T) and the dew point temperature (Td) of Urbana, IL; St. Louis, MO; Milwaukee, WI; and Austin, TX. Relative humidity is closely related to the difference between the actual air temperature and the dew point temperature. A smaller difference between these temperatures indicates higher relative humidity, as the air is closer to being fully saturated with water vapor.
Urbana, IL: T = 52°F, Td = 32°F (difference = 20°F)
St. Louis, MO: T = 69°F, Td = 46°F (difference = 23°F)
Milwaukee, WI: T = 22°F, Td = 21°F (difference = 1°F)
Austin, TX: T = 90°F, Td = 40°F (difference = 50°F)
Given this analysis, Milwaukee has the smallest difference between the temperature and the dew point, indicating it has the highest relative humidity among the listed cities, making the correct answer (c) Milwaukee.
Why are structures built on soft sand or mud often destroyed in an earthquake when nearby structures built on bedrock remain essentially undamaged?
Answer: An earthquake is the shaking of the surface of the earth caused by volcanic activity or movement around geological faults.
Earthquakes can be of a high magnitude or low magnitude. (magnitude is the size of the earthquake or the frequency of the vibrations caused by the earthquake.)
Earthquakes shakes with stronger vibrations in soft sand or mud that's why structures built on soft sand or mud are often destroyed in an earthquake.
Earthquakes shakes with small vibrations on bedrock because of the rigidity of the bedrock.
Identify the TRUE statement. Choose one:
A. Our Sun is the only star we know of that has planets associated with it.
B. The only two planets with moons are Earth and Jupiter.
C. The Sun accounts for almost 50% of the Solar System's mass.
D. The composition of the giant (Jovian) planets is mainly gas and ice.
Answer:
D. The composition of the giant (Jovian) planets is mainly gas and ice.
Explanation:
Giant planet that is not composed mostly of rock or other solid matter but of fluids (gas and ice); although said planets may have a rocky or metallic core. It is believed that such a nucleus is probably necessary for a gas giant to form, but most of its mass is in the form of gas, or compressed gas in a liquid state.
Unlike rocky planets, gas giants do not have a well defined surface. Terms such as diameter, surface area, volume, surface temperature or surface density can refer to the outer layer seen from outside, for example from Earth.
In the Solar System there are four gas giants: Jupiter, Saturn, Uranus and Neptune. These planets are also known as the "Jovian planets." Uranus and Neptune have been considered by scientists as a separate subclass of giant planets, frozen giants, also called "uranium planets", due to their structure mainly composed of ice, rock and gas. They differ from "traditional" gas giants, such as Jupiter and Saturn, because their proportion of hydrogen and helium is much lower, mainly because of their greater distance from the Sun.
Sediments which are poorly sorted and made of a variety of minerals could have been deposited by:________.
a) a volcanic eruption.
b) turbidity currents.
c) the wind.
d) a river delta.
e) a glacier.
Answer: B) Turbidity currents
Explanation: Turbidity currents are large scale water movements which picks and carries different particles in the form of sand,rocks,minerals and other materials which are poorly sorted as it flows to the point of depositon.Turbidity currents contain particles of different sizes, types and shapes as it flow,as it picks larger particles it's speed continue to Turbidity currents are caused my geological movements, earthquakes and cracked slopes. Other options don't carry as much variety of materials as Turbidity currents.
Final answer:
Glaciers deposit poorly sorted sediments with a variety of minerals due to their ability to carry an unsorted mixture of materials, leading to glacial till upon melting.
Explanation:
Sediments which are poorly sorted and composed of a variety of minerals could have been deposited by glaciers. This is because glaciers can carry a mixture of sediment sizes as they move, and when a glacier melts, it deposits an unsorted mixture of materials ranging from fine clay to large boulders, known as glacial till. Wind-blown sands, characteristic of eolian deposition, would be well-sorted, as the wind can only transport finer particles. Turbidity currents could also deposit poorly sorted sediments in the form of turbidite sedimentary deposits, but these are typically sorted by density due to water transport. Rivers in deltas and volcanic eruptions can create unsorted deposits, but to a lesser degree compared to the distinct chaotic mixture of a glacial deposit.
True or false?
The growth rate of a certain population increases very quickly for a time and then levels off to zero. The most likely reason that the growth rate leveled off to zero is that the population reached the carrying capacity of that environment.
Answer:
It is True.
Explanation:
This statement is true because this statement tells us a very rational point of view as well as a fact that the growth of population increases very quickly for a certain point then after that it growth drops to zero. The reason for the drop in the growth to zero is due to the many factors which is explained by the term "Carrying Capacity of Environment".Carrying Capacity of an environment is very crucial for the people living in that environment. It is basically measure of the ability of the ecosystem to sustain itself by providing basic needs to maximum number of the human beings. The basic needs include shelter, food, water etc.When a carrying capacity is reached, then its means that the maximum people are getting basic needs from the ecosystem. Then further increase in population results in the deficiency of the resources for food, water, shelter etc so, as a result that result in the decrease of population due to competition of survival and other factors.Which of the following geological processes adds new rock to the surface of the earth?
A) Volcanic activity
B) Glacial activity
C) Soil erosion
D) Weathering
Answer: A) Volcanic activity
Explanation: Volcanic activity which includes volcanic eruptions is a high temperature process through which rocks such as metamorphic rock melts through large scale earth movements and transportation its it's Magma materials into another location adding new rocks.
Volcanic activity is a geological process which add new rocks to the Earth,the other options involved breakdown processes which doesn't add new rocks.
Glacial activity involves the melting of ices due to high temperature.
Soil erosion is the movement of soil particles caused by mainly by water movement,air etc.
Weathering is the breakdown of rocks into small pieces.

Albedo is the tendency of a surface to reflect solar energy instead of absorbing it, and snow and ice have a much higher albedo than water. Over the last several decades the amount of the Arctic Ocean that has ice on it has been decreasing, thereby exposing more and more of the Arctic Ocean to the atmosphere each summer. Would this cause the total absorption of heat in the Arctic to increase or decrease?
Answer:
increase
Explanation:
The depletion of the ice sheets in the Arctic Ocean will expose more of the ocean to the incoming solar energy. Because water has a much lower albedo than ice, it absorbs more energy and so takes in more heat than did the sea ice. The net result is increased heat absorption and further loss of sea ice in the Arctic region.

The superhot liquid expands in volume, reducing its confining pressure, and flashing it into steam. Which geologic feature matches this description?
Choose one:A. a geyserB. a hot springC. a mud potD. an artesian spring
Answer:
Option (A)
Explanation:
Geysers are distinctive geological features that are formed in the region, where the water below the surface of the earth is heated due to the high temperature or the heat energy radiated into the surface of the earth from the core. These are known as geothermal energy. This heats the water so much that it exceeds the surface boiling temperature and eventually rises up towards the surface.
These are areas of volcanisms that lead to the eruption of hot water forming steams, through the vents.
Thus, the correct answer is option (A).
The atmospheric cooling that occurs where and when aerosol pollution is the greatest is an example of:
Answer:
Aerosol effects
Explanation:
Aerosol effects
Aerosol is a small packets of air that remain in the atmosphere.
We know that the sun is the major source of energy on the earth but it is not true that we receive all that energy. some portion of that energy is either absorbed by aerosol or clouds . therefore it keep the temperature of earth little cool. However some aerosol also reflect the sun energy and this depends on solely on the composition of particle that make aerosol.

The nebular theory can be corroborated by observations of nebulae condensing. However, finding celestial bodies without any surrounding nebular matter could challenge the theory.
Explanation:The hypothetical discoveries you are referring to will be sorted based on the Nebular Theory. The Nebular Theory suggests that planets and stars were formed from the condensing of a nebula, due to gravity. A discovery consistent with this theory is the observation of a nebula gradually condensing. On the other hand, an example of a discovery that is not consistent with the theory is finding mature celestial bodies without any surrounding nebular matter. These inconsistencies may challenge or necessitate amendments to the Nebular Theory.

Answer:
B) their economies have shifted from agriculture to manufacturing
Explanation:
East Asian countries moved into manufacturing. Many companies from High-Income Countries (HICs) began to manufacture products in Asia due to the low cost for labor, land and resources. This was only increased by the reliability and technological developments by transport options. Urbanization happened faster as the agricultural industry needed less labor intensive workers and more machine operated farming equipment on a commercial scale. The populations also rose dramatically and the labor prices stayed down.
Directly seaward of the continental shelf is a more steeply sloping region called the: mid-ocean ridge. continental rise. trench. abyssal plain. continental slope.

Why are most of Earth's deserts located in the subtropical zone?
A. These regions receive more sunlight than the equatorial region.
B. These regions receive less sunlight than the equatorial region.
C. These regions are very warm but less humid than other regions.
D. These regions are very warm but more humid than other regions.
Answer:
C) These areas are very warm but less humid than other regions.
Explanation:
It is an area of high atmospheric pressure. This means that cold air is descending and will return to the lowest pressure, towards the equator. The air is dry and rarely forms clouds as it is descending. This allows for a maximum of incoming solar radiation to heat the ground surface. The air moves towards the equator becoming more humid and rise, which helps provide rain for the rainforest. By the time it reaches the desert area it is once again dry and descending.
These regions are very warm but less humid than other regions.

Answer:
Striations- As they are the scratches and erosive patterns which are formed on the bed rock due to the glacial abrasion."
Explanation:
Now, in the early times or many millions years ago the glacial layers passed through different regions of the land, leaving marks behind. Some of these marks can be analyzed as the parallel grooves in the rock called as striations.
The glacial abrasion is the process during which the bottom rocks are glided over the layer of the land, creating different patterns on it called as striations.

In 1964, the earthquake in Alaska damaged the Turnagain Heights and this earthquake was the strongest earthquake in the USA that was recorded. The magnitude was of about 9.2 on Richter Magnitude Scale.The statement is valid for the damage of Turnagain Heights which says that "A weak, subsurface, clay layer failed, resulting in numerous landslides." as it was the primary cause.The statement "It was hit by a large tsunami and then buried by a rock avalanche" was not the reason of it. The earthquake led to the Tsunami which increased the scale of destruction.The statement " It burned in a fire set off by broken gas lines." is also not valid as it was not cause of damage of Turnagain Heights. The gas lines broke due to the earthquake.All true oceanic islands are ________ in origin.
A) volcanicB) collisionalC) sedimentaryD) erosionalE) metamorphic
Answer:
A) volcanic
Explanation:
Oceanic island are formed where their is volcanic eruption on the sea floor . This island rises above the sea water and can experience active volcanoes overtime.
This island are formed when the oceanic plates collides with the more active continental crust. Example of this island is the Aleutian Island. The oceanic crust been denser, subduct under the more active and less dense continental crust. This subduction brings about crustal migration of molten magma from the earth interior .
This molten magma due to pressure may erupt through the vents on the sea floor to form oceanic islands . Generally, this eruption build up to form new crust and invariably form a volcano on the seafloor. This is why most oceanic islands are volcanic in nature . And this island are also called volcanic Island.
