Answer 2

"The climate was warmer and wetter" can be determined about the climate during the 15-year. Thus, option 'A' is the correct option.

What is climate?

The climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of climatic variables over a period of time that can range from a few months to many millions of years. Temperature, humidity, air pressure, wind, and precipitation are a few of the meteorological factors that are frequently monitored.

In a larger sense, climate refers to the interactions between the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere, which together make up the climate system. A location's latitude, longitude, topography, altitude, land use, and proximity to water bodies and their currents all have an impact on the climate there. Climates may be categorized based on usual and average factors, most frequently temperature and precipitation.

Which could be the location where water emerges from the surface as a spring?

Answers

Final answer:

Springs occur where the groundwater intersects with the surface, often where the landscape rises above and then falls below the groundwater level. In terms of figuring out which location on a cross-section of a landscape would contain a spring, it would be where this condition is met. Specifics cannot be provided without viewing the image.

Explanation:

Springs are naturally occurring phenomena where water comes out from the ground, or specifically, from the 'groundwater' level. This usually happens in areas where the groundwater below the surface intersects with the surface. The groundwater is stored in a layer of rock called the aquifer from where it escapes due to pressure.

In this context, if you are viewing a cross-section of a landscape and trying to identify where a spring may occur, you would want to look for a location where the landscape rises above and then falls below the groundwater level. This could potentially be a location where water emerges from the surface as a spring. However, without viewing the image, it's not possible to specify whether location 1, 2, 3, or 4 is most likely to be a spring.

Final answer:

A spring is where groundwater emerges naturally from the earth's surface, typically at the intersection of the water-saturated soil or rock with the ground's surface. This usually happens at the base of hills or mountains. Without an image for reference, specific locations cannot be pointed out.

Explanation:

A spring is typically where groundwater flows naturally from the earth's surface. This can occur at the boundary where the water-saturated soil or rock meets the surface of the ground. Based on the information given and without an image to refer to, it's impossible to specify which numbered location a spring would emerge from. However, a spring would be commonly found at the base of hills, mountains, or other places where the underground water table intersects with the surface topography. It is also important to mention that the formation of a spring might require a particular geological condition, usually permeable and impermeable layers of rock.

You just discovered Amebelodon, a shovel-toothed elephant, and you are trying to figure out how old it is. As you examine the sediment you discover a couple species of dinoflagellates that were previously studied and dated. Nelsoniella aceras lived between 80-85 million years ago and Odontochitina lived between 68-82 million years ago. Based on fossil correlation how old is Amebelodon?
A) 68-85 million years old
B) 80-82 million years old
C) 81 million years old
D) 79 million years old
E) D = D0 + N(t) (eλt − 1)... so I have no idea!

Answers

A is the correct answer. Choose the largest variation of years

Answer:

Option (A)

Explanation:

Amebelodon refers to the ancestor of elephants which were extinct a long time back and they belonged to the Amebelodontidae group of proboscideans. They are closely related to the modern day elephants and the early mammoths. They were comprised of shovel-teeth.

In the given condition, a shovel-tooth of an Amebelodon elephant is found in the sediments, which was associated with two other couple species of dinoflagellates, whose age is previously noted. The two species are Nelsoniella aceras and Odontochitina, which were about 80-85 million years ago and 68-82 million years ago respectively.

Since the Amebelodon tooth and the other two dinoflagellate fossil species are found in the same sediments, one can apply the principle of biostratigraphy, and determine the relative age of the rocks. Biostratigraphy refers to the correlation of rocks based on the presence of fossils.

Thus, the age of the Amebelodon will be somewhere between the range of 68-85 million years old.

Hence, the most appropriate answer is option (A).

Answers

Final answer:

Methods to prevent wind erosion include rotating crops, mulching soil, installing windbreaks, growing more vegetation, and avoiding soil compaction. These methods help in reducing the force of the wind, preventing the soil surface from becoming bare, and hold the soil in place.

Explanation:

To prevent wind erosion, you can utilize multiple methods, including rotating crops, mulching soil, installing windbreaks, growing more vegetation, and avoiding soil compaction. Applying these procedures can significantly aid in reducing soil loss caused by wind. For instance, rotating crops allows the soil to regain nutrients while mulching soil prevents the surface from becoming bare. Through installing windbreaks, such as trees or bushes, the force of the wind can be mitigated thereby reducing the possibility of wind erosion. In addition, growing more vegetation helps to hold the soil in place while reducing soil compaction can reduce the chances of the soil being blown away.

For the human species which is the major concern on the issue of overpopulation

Answers

How to provide for everybody would be the most major concern

Answer:

Depletion and destruction of natural resources is the major concern on the issue of overpopulation.

Explanation:

It is like an elephant in a room where no one would want to talk about. Nowadays people are concerned more about the climate change which is definitely important but the root cause has to be understood. Here the root cause implies the effect of substantial increase in human population. The population in 1960 is going to be doubled soon with the increase in head count. The negative impacts like human emissions through vehicles, industries have already started showing their effects on the planet. Global warming is on the rise to deplete ozone layer, melting the glaciers. Everything is interdependent making it a high time to address the current issues.  Unless family planning norms are strictly followed, this issue will never get subsided. Humans existing and reducing the negative effects will not work, but reducing head counts only will slowly solve the issue. All the natural resources will get used up soon making it difficult for the future generations to survive.

If subduction occurs beneath the continental crust a(n) _____________ is formed. If subduction occurs beneath the oceanic lithosphere, a(n) __________ is formed. A) island arc, volcanic arc B) volcanic arc, island arc C) transform fault, transform arc D) transform arc, transform fault

Answers

The answer is B) volcanic arc, island arc.

The first one would be island arc as subduction occurs beneath the continental crust. When it occurs, the compressional force placed upon the continential plate will cause the rock to bend and arc up form a series of volcanoes leading to the formation of volcanic arc.

The second one would be island arc as subduction occurs beneath the oceanic lithosphere. When subduction forced the crust to bend, rocks are compressed and arc up, forming a series of island, the formation of island arc then occurs.

C and D is incorrect as no transformation has take place.

The western slope of the Cascade Mountains receives the heaviest amounts of rainfall and snowfall, this is the: A. leeward slope B. windward slope C. chinook slope D. semiarid slope

Answers

The answer is; B

This western part of the slope faces the Pacific ocean. Therefore sea breeze from the ocean in the daytime, which is warm and moist, is forced up the mountain where it cool as it ascends and the moisture condenses into precipitation. This is why this side is the windward. The dry air then descend into the leeward side (the eastern region of the mountain). This part of the mountain is drier than the western region.


The correct answer is - B. windward slope.

The western side of the Cascade Mountains are open towards the Pacific Ocean. The air masses that are coming from the Pacific are in general stopped at the western slopes of this mountain range. This basically means that when there's warm and wet air masses coming from the Pacific, the western side of the mountains get pretty much all of the rainfall or snowfall, and that is because the mountains themselves are a natural blockade for the air masses, so they accumulate and empty themselves.

The side that is getting the rainfall and snowfall, in this case the west side, is the windward side of the mountains. The other side of the mountains that receives dry air masses is the leeward side.

Which city is closer to Greenwich, England: Los Angeles or X'ian, China ( 34 N, 209 East

Answers

Final answer:

Los Angeles is closer to Greenwich, England than X'ian, China, based on longitude measurements, with Los Angeles at 118°W and X'ian effectively at 151°W.

Explanation:

To determine which city is closer to Greenwich, England, we use longitude as a key reference point. Greenwich is at 0° longitude. Los Angeles' longitude is approximately 118°W, while X'ian, China's given longitude is 209°E. However, since longitudes only go up to 180°, the corrected longitude for X'ian should be 151°W (360°-209°=151°).

We know that when traveling east from the prime meridian, longitudes increase up to 180°E, and the same increase up to 180°W when traveling west. Thus, the distance in longitude from Greenwich to Los Angeles is 118°, and to X'ian, it is 151°.

In conclusion, Los Angeles is closer to Greenwich, England than X'ian, China, in terms of longitude.
