Question

fertile soil is most often found:
a. along the equator
b. where temperatures are relatively mild and precipitation is relatively high
c. where its hot and dry
d. in higher elevations

Explanation:

Fertile soil requires a balance of factors. Mild temperatures and relatively high precipitation (option B) support the biological activity (like decomposition of organic matter by microbes) and chemical processes (such as nutrient cycling) that make soil fertile. Along the equator (A), the intense leaching (due to heavy rainfall) can wash away nutrients. Hot - and - dry regions (C) lack the moisture for significant plant growth and organic matter accumulation. Higher elevations (D) often have thinner soils, colder temperatures that slow down biological activity, and may be more prone to erosion.

Answer:

B. where temperatures are relatively mild and precipitation is relatively high
