Question

question 2 of 5
which two factors would lead to fertile soil?
a. a moderate amount of rain
b. a dry and hot climate
c. a very high altitude
d. temperatures of 25 - 30°c

Explanation:

• Option A: Moderate rain helps in soil formation and nutrient retention. It allows for proper water - soil interaction, facilitating the movement of minerals and organic matter within the soil.
• Option D: Temperatures in the range of \(25 - 30^{\circ}C\) are conducive to the activity of soil - forming organisms (like bacteria, fungi, and earthworms). These organisms break down organic matter, which enriches the soil.
• Option B: A dry and hot climate leads to soil erosion (due to lack of vegetation cover as plants struggle in such conditions) and reduced soil - organism activity.
• Option C: Very high altitudes usually have thin soils. The harsh environmental conditions (cold, strong winds) limit the accumulation of organic matter and soil - building processes.

Answer:

A. A moderate amount of rain, D. Temperatures of \(25 - 30^{\circ}C\)
