Question

Why is the soil on mountain slopes infertile and the soil in valleys fertile?

Answer 1

Answer:

The main reason is slope and high altitude of mountains with low water availability.

Explanation:

• The soil of mountain is present in thin layer with low humidity.
• And due to slope like  nature of mountains when it rains, rain water does not absorb in soil while it washes away fertile soil and nutrient with itself.
• While the soil in valleys is fertile because valleys are plains with thick layers of soil having different nutrient types.
• And when it rains, rain water collected and absorbed in plain land making soil fertile.
