Question

Deep soils are characteristic of tropical regions whereas thin rocky soils are characteristic of high latitudes.

This is a natural demonstration that ________.

A) chemical wreathing rates are much higher in the tropics than high latitudes
B) physical weathering and erosion rates are higher at high latitude, removing soil faster than it can form
C) all of the high latitude regions lost their soil in recent times
D) humans living at high latitudes have destroyed the soils by bad farming practices

Answer 1

Option (A)

Step-by-step explanation:

The tropical regions are somewhat closer to the equator, and the temperature and the amount of incoming solar radiation is relatively high. Due to this, the tropical areas are subjected to high precipitation, as a result of which the chemical reactions take place at a much faster rate. This directly leads to the weathering and erosion of rocks in the tropical region.

Therefore, the tropical regions are characterized by the presence of deeper soils and rich in mineral nutrients that are essential for the growth of plants and trees, whereas the higher latitude areas are characterized by the presence of thin rocky soil that lacks essential minerals.

Thus, the correct answer is option (A).
