Which of the following climates is most suited for physical weathering?


A. Warm
B. Dry
(C. Hot)
D. Cool

What latitudes are most likely to see glaciers?

(A. 90° N and 90° S)
B. 30° N and 30° S
C. 45° N and 45° S
D. 10° N and 10° S

For the first question, physical weathering refers to the breakdown of rocks and minerals without any chemical changes. Among the given options, climates with hot temperatures are most suited for physical weathering. Therefore, the correct answer is C. Hot.

For the second question, glaciers are large masses of ice that form in areas where the temperature remains below freezing for a significant portion of the year. The latitudes closest to the poles are most likely to see glaciers. So, the correct answer is A. 90° N and 90° S.

To determine which climate is most suited for physical weathering, we need to understand the factors that contribute to this process. Physical weathering refers to the breakdown of rocks into smaller fragments without involving chemical changes. Some of the main factors that contribute to physical weathering include temperature fluctuations, freeze-thaw cycles, humidity, and the presence of water.

Among the given options, the most suitable climate for physical weathering would be:

C. Hot

Hot climates experience higher temperatures which can cause expansion and contraction of rocks, leading to the formation of cracks and fractures. This is known as thermal stress and is a significant factor in physical weathering. Additionally, hot climates often have intense solar radiation, which can further contribute to the weathering process.

Now, let's move on to the next question:

Glaciers are large masses of ice that form when the accumulation of snow exceeds its melting. They shape the land through a process called glacial erosion, which involves the movement of ice and the scraping of rocks. Glacial activity is mostly associated with high latitudes and areas that experience cold temperatures.

Among the given options, the latitudes most likely to see glaciers are:

A. 90° N and 90° S

These latitudes represent the polar regions, where continuous cold temperatures allow for the formation and maintenance of glaciers. The extreme cold at the poles ensures that ice and snow do not melt significantly, resulting in the accumulation and movement of glaciers.
