I'm pretty sure it's A... If its wrong let me know.
ANSWER:
Folds in rocks form when the rock bends. Meanwhile, faults form when the rock breaks. Various factors such as temperature, strain, confining pressure, and composition of the rock play a part in bending or breaking of the rocks.EXPLANATION:
Folds and faults are two recognizable geological structures which are created due to the deformation of the rocks due to various factors. These structures in rocks arise due to the pressure and stress in the tectonic plates and the rocks.what is the geological history of hulunbuir grassland?

I WILL MAKE YOU THE BRAINLIEST Use the images on-screen to complete the activity and identify the forces involved in each image of stressed rock.
Forces used for folded rock near Palmdale, CA:
The answer is; compressional force
This type of force causes the particles, of the mass experiencing the force, to compact inwards. This cause the rock layers to fold. This type of force is experienced by the crust at convergent boundaries where two tectonic plates are colliding. When the compressional force exceeds the elasticity of the rock layers, faulting occurs.
Answer:
The answer is: compressional force
Katrina wanted to find out more about Wegener’s hypothesis because it didn’t explain how continental drift took place. Explain how scientists discovered the mechanism for the continents moving.
Answer and Explanation:
The mechanism which is responsible for moving the plates that bring change in the position of the continents is the convection in the asthenosphere.
Henry Hess, a geologist and an American Navy officer in the World War II, discovered that the sea floor and the the Mid Atlantic Ridge is spreading which helped the the scientists in studying and understanding the mechanism of how the plates move.
The theory of plate tectonics synthesizes these observations and provides a comprehensive model for the movement of Earth's lithospheric plates. It explains not only how continents move but also many other geological phenomena, such as mountain building, earthquakes, and volcanic activity.
Katrina's curiosity about Wegener's hypothesis is understandable since Alfred Wegener, who proposed the theory of continental drift in 1912, did not provide a convincing mechanism for how the continents could move across the Earth's surface.
The mechanism for continental drift was later explained by the theory of plate tectonics, which was developed in the 1960s. This theory is supported by several key pieces of evidence:
1. Seafloor Spreading: The discovery of the mid-ocean ridge system and the process of seafloor spreading provided a mechanism for the creation of new oceanic crust. Magma from the Earth's mantle rises to the surface at mid-ocean ridges, creating new crust as tectonic plates move apart.
2. Paleomagnetism: Studies of the magnetic minerals in rocks from different locations and of different ages showed that the Earth's magnetic field periodically reverses.
3. Convection Currents in the Mantle: The movement of tectonic plates is driven by convection currents in the semi-fluid asthenosphere, which is located beneath the rigid lithosphere.
4. Earthquake and Volcano Distribution: The distribution of earthquakes and volcanoes along plate boundaries provided further evidence for the movement of plates. .
5. Continental Fit and Fossil Evidence: The jigsaw-like fit of the continents and the distribution of fossil plants and animals across continents that are now widely separated also support the idea that the continents were once joined together and have since drifted apart.
Where are extrusive rocks formed? A. in the sea B. in the mantle C. in the core D. on the surface of the earth

Answer:
The cross-section from Vishnu Schist to Redwall Limestone reflects multiple eras and environments. From the antiquity of the Vishnu Schist and the beach environment of Tapeats Sandstone, through changing conditions of Bright Angel Shale, Muav Limestone, and Temple Butte Limestone, to the marine cliffs of Redwall Limestone, each layer adds to the geological tale.
Explanation:The Vishnu Schist, located at the very bottom of the Grand Canyon, is the oldest unit visible in the area, evidence of metamorphic processes that shaped its high-grade metamorphic rocks.
Above the Vishnu Schist is the layer of Tapeats Sandstone, demarcating the Great Unconformity—an extensive time gap. This sedimentary layer formed in beach-like environmental conditions.
Overlying the Tapeats Sandstone, the Bright Angel Shale demonstrates adaptation to more marine conditions marked by the availability of mud deposits.
The Muav Limestone, above the Bright Angel Shale, shows a return to clear, warm, shallow seas as illustrated by its dense limestone makeup.
Temple Butte Limestone contrasts the previous strata, hinting towards isolated bodies of water with its lenses and pockets structure.
Finally, the Redwall Limestone at the top, now subject to weathering and erosion, suggests a wholesome environment with its massive marine cliffs.

Explanation:
More than 60% of the resources and services provided by the planet's ecosystems are degraded, and the consequences of this destruction could worsen significantly over the next 50 years, warns an international study published in 2015. Freshwater, fisheries, and air and water regulation Water, regional climates, natural disasters and pests are the most endangered natural resources and services, says the Millennium Ecosystem Assessment, prepared by 1,300 scientists from 95 countries. Degradation of 15 of the 24 ecosystems studied increases the likelihood of abrupt changes that can severely affect the well-being of all biodiversity on the planet, such as the emergence of new diseases, sudden deterioration in water quality, the collapse of fishing grounds and changes in regional climates.
The extinction rates of animal and plant species are increasing on an unprecedented scale. The average abundance of native species in most major terrestrial habitats has fallen by at least 20%, mostly since 1900. More than 40% of amphibian species, almost 33% of corals and more than one third of all mammals are threatened. .

What would happen if plate motions were reversed?
A. A volcanic arc would form
B. New, younger mountains would form
C. A continental rift would form
D. An oceanic trench would form offshore
If plate motions were reversed, a continental rift would form. Thus, Option (C) is correct.
A continental rift is a process where a continent splits apart, resulting in the formation of a new ocean basin. This occurs when the lithospheric plates move away from each other, leading to the thinning and eventual breakage of the continental crust.
Reversing plate motions would cause the plates to converge instead of diverge, inhibiting the creation of a new ocean basin. Instead, the compressional forces generated by the convergence would give rise to mountain building.
Thus, Option (C) is the correct choice for the scenario where plate motions are reversed, as it accurately reflects the consequences of such a change.

What kind of fault indicates that crust has been pulled apart?
a.reverse
b.strike-slip
c.normal
d.all of the above
I believe the answer is A
Answer:
d.all of the above
Explanation:
Geological fault is the rupture or splitting of a block of rocks or narrow bands of the surface that is responsible for the displacement of its parts. The accumulation of energy and its eventual release in geological fault zones is one of the factors responsible for the occurrence of earthquakes.
The types of geological fault vary according to the criteria used in their classification. In the present approach, they are typified in three different forms: normal, reverse, and transcurrent.
In the normal type fault, the split occurs when a block “descends” or lowers from the fault surface. This occurs when the pressure exerted on the region causes a negative tension.In reverse-type failure, splitting occurs when a block “rises” in relation to the fault, raising its surface. This happens when tectonism causes a tension responsible for compressing the space occupied by the rock layers.In the transcurrent fault, also called horizontal fault, there is a parallel movement between the two blocks, which can be caused by inverse vectors of horizontal forces applied on each rock segment.Which letter identifies the location of the Canadian Shield region of North America

What is the scale of the map? For this activity, you will use centimeters.
1 cm = 405 km
Choose one strip of seafloor rock. What is the age of the rock?
20
Use your ruler to measure the distance of the strip from the Mid-Atlantic Ridge.
3 cm
Using the calculator, multiply the answer to #4 by 405 to figure out its distance in kilometers. Round to the nearest whole number.
i multiply 3 by 405 and get 1215 km
Determining Rate of Spreading
Use the age of the rock you have chosen and its distance from the Mid-Atlantic Ridge to calculate seafloor spreading.
First you will find out how fast the seafloor is moving away from the ridge on one side. Use a calculator to divide the answer to #5 by the answer to #3. Round to the nearest whole number.
#5 km ÷ #3 million years = km/million years
Final answer:
The scale of the map is 1 cm = 405 km. Using the scale, we can calculate the distance from the Mid-Atlantic Ridge to the seafloor rock strip. By dividing this distance by the rock's age, we can determine the seafloor spreading rate.
Explanation:
The scale of the map is 1 cm = 405 km. So, if you measure a distance of 3 cm on the map, you need to multiply it by 405 to get the actual distance in kilometers. In this case, 3 cm multiplied by 405 equals 1215 km. Therefore, the distance from the Mid-Atlantic Ridge to the strip of seafloor rock is approximately 1215 km.
Next, we can use the age of the rock, which is given as 20 million years. To calculate seafloor spreading, we need to find out how fast the seafloor is moving away from the ridge on one side. Divide the distance of 1215 km by the age of 20 million years. The result is approximately 60.75 km/million years.
Therefore, the seafloor spreading rate on one side of the Mid-Atlantic Ridge is approximately 60.75 km/million years.
The rate of seafloor spreading calculated from the student's activity is 61 km per million years, using the map scale of 1 cm = 405 km and a rock strip that is 20 million years old and 3 cm away from the Mid-Atlantic Ridge.
To calculate the rate of seafloor spreading, one must use the scale of the map and measurements taken from it. The given map scale is 1 cm = 405 km, and the chosen strip of seafloor rock is 20 million years old and is located 3 cm from the Mid-Atlantic Ridge. By multiplying 3 cm by the scale value (405), the distance from the ridge is determined to be 1215 km. To find the rate of spreading, divide the distance by the age of the rock:
1215 km (distance from the ridge) ÷ 20 million years (age of the rock) = 60.75 km/million years
After rounding to the nearest whole number, the rate of seafloor spreading in this example is 61 km per million years on one side of the ridge.

A volcano violently erupts near a small town and wildlife preserve. Which effects might occur? Check all that apply.
A. Lava destroys homes and farmland.
B.New species form at the wildlife preserve.
C. Many wildlife species become extinct.
D. Ash and dust fill the air and reduce sunlight.
E.Organisms and populations on the wildlife preserve die.
The correct answers are:
A. Lava destroys homes and farmland;
The lava flows can not really be stopped, so what they manage to reach will be destroyed, homes and farmlands on its way included.
D. Ash and dust fill the air and reduce sunlight;
A strong and violent volcanic eruption will release lot of ash and dust, and that will for sure affect the atmosphere, especially in close proximity to the volcano, which will reduce the sunlight, and make the climate colder.
E. Organisms and populations on the wildlife preserve die;
The lava flows, pyroclastic material, poisonous gases, ashes, will all contribute to death to every living organism that will not be able to escape on time, be it humans, animals, or plants, they will all die.
The answer is:
Lava destroys homes and farmland.
Ash and dust fill the air and reduce sunlight.
Organisms and populations on the wildlife preserve die.
When a volcano erupt, it will release magma that previously kept under the earth surface, which typically has the temperature of 700 Celcius. This would kill a lot of plants animals near the volcanoes. As it erupted, the volcano also release ash and dust that potentially caused breathing difficulties. As the dust rise up to the air, it would reduce sunlight and disrupt the photosynthetic process that being done by nearby palnts.
