1. What causes melting at a hotspot?
2. Describe how the Hawaiian hotspot formed a chain of volcanoes.

Answers

Answer 1

1) Well, once again, if you imagine that a volume of rock from great depth is moving upward until it gets to that level, it's undergoing a substantial amount of decompression. And because of that decompression, it starts to melt here. We get partial melting that forms magma and magma rises through the lithosphere, and erupts at the surface.

2) Under the Hawaiian Islands, there is a volcanic “hot spot,” a hole in the Earth’s crust that allows lava to surface and layer. Over millions of years, these layers form mountains of volcanic rock that eventually break the surface of the Pacific Ocean, forming islands. As the Pacific Plate very slowly moves across the hot spot, new islands are formed.

Explain how air pressure is responsible for creating tropical rainforest environments.


Explain how air pressure is responsible for creating hot desert biomes.

Answers

Explanation:

Differences in temperature lead to variations in air pressure around the world. Low-pressure areas are created when air rises. It is called low pressure because the weight of the air above the Earth's surface is lower than average. High-pressure areas are created when air sinks. It is called high pressure because the weight of the air is above average when it sinks to the Earth's surface.

Low-pressure areas are associated with cloud and precipitation (rainfall) because:

as the air rises it cools, condenses and forms clouds

the water droplets in the clouds increase in size

they eventually become too heavy to be held and fall as precipitation

The air above the Equator is very hot and rises, creating an area of low pressure. The Equator experiences high amounts of rainfall due to this rising air resulting in a warm and wet equatorial climate (eg the Amazon and Congo tropical rainforests).

High-pressure areas are associated with dry, warm and settled weather conditions. This is because sinking air does not result in precipitation.

17. In which of the following world regions has the Green Revolution had the least impact on agriculture?
a East Asia
b. South Asia
c. Southeast Asia
d. Central America
e Sub-Saharan Africa

Answers

Answer:

e. Sub-Saharan Africa

Explanation:

In Sub-Saharan Africa, world regions the Green Revolution had the least impact on agriculture. The correct option is e.

What are the negative impacts of the Green Revolution?

These include a decline in soil fertility, contamination of the soil, soil erosion, a lack of water, a decrease in genetic diversity, increased susceptibility to pests, a decrease in the amount of nutrient-dense food crops available to the local population, rural poverty, the eviction of small farmers, and an increase in social unrest.

While the Green Revolution, which started in the 1960s, had a significant impact on agriculture in other areas like East Asia, South Asia, and Southeast Asia, it has had limited success in Sub-Saharan Africa due to a variety of reasons, including inadequate infrastructure, a lack of access to credit, and a lack of modern inputs like fertilizers and high-yielding seed varieties.

Thus, the ideal selection is option e.

Can the change in the # of hours of daylight over the course of a year help (it doesn't have to be the only factor) explain the differences in temperature between summer and winter?

Answers

Answer:

Yes.

Explanation:

The duration of hours of the day is longer during the summer and shorter during the winter and this influences the temperature in these two seasons. As the day is longer in the summer, it means that the hemisphere that this summer has more exposure to the sun and therefore has higher temperatures. The opposite happens in the winter, as there is less exposure to the sun, due to the shorter day, which can help in decreasing the time.

Answer:

Suggest what countries can do to make deserts more suitable for farming.

Answers

Answer:

Modern irrigation systems, redirecting of streams or parts of them, and using drought resilient plants, will help gradually convert the desert and make it suitable for farming.

Explanation:

A lot of countries in the world have problems because a smaller or larger part of their territories is occupied by deserts, and on top of it, it seems like the deserts are expanding. The deserts as they are cannot really be used for anything, including farming, but this can be changed in managed properly.

In order to convert desert into land suitable for farming, a good and reliable irrigation system needs to be set up, at least for the first few decades. Ares that are relatively close and maybe have a surpluss of water, or it is a terrain where it cannot be used for farming or anything practical, the streams can be redirected toward the desert. This will bring in highly fertile sediments, a constant supply of water, and increasing humidity in the area. The plants that initially need to be used should be ones that are highly resilient to high temperatures and drought, but also leave a solid amount of biomass so that the soil can get a fertile top layer. Plants that can be very suitable are rosemary and succulents, and they will also be economically beneficial in the meantime while the transformation lasts as they can be easily sold on the market.

A. Location W
B. Location X
C. Location Y
D. Location Z

Answers

Location Z, because it is placed near a convergent boundary

Based on the map, the volcanic activity would most likely be found at Location Z. Thus the correct option is D.

What is a map?

A map is referred to as a pictorial representation of different places used to identify the direction and reach the next location. They help the user to identify sea, rail routes, and roads to reach the destination.

Divergent plate boundaries and convergent plate boundaries are the two types of continental plates that are most likely to result in volcanic activity. According to the map, Location Z, which is part of the convergent plate, is where volcanic activity would most likely be found.

Volcanoes originate in two configurations either an oceanic plate falls beneath another oceanic plate, or an oceanic plate declines beneath a continental plate.

Therefore, option D is appropriate.
