5. What is soil erosion? Write the measures to prevent soil erosion.

6. What are the climatic factors that affect the soil profile?​

Answer 1

Explanation:

1. Role of water in soil formation is as follows: Due to continuous movement of rain and fast flowing river water, rock pieces collide and break down into smaller rocks, then into pebbles, then into tiny finer particles that make up the loose stuff we call soil.
2. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories. ... Other, less common minerals include calcium, magnesium, and sulfur. The biotic and abiotic factors in the soil are what make up the soil's composition.
3. a sandy soil has the highest proportion of sand particles and the lowest proportions of silt and clay (within the fine earth fraction), a clayey soil has the highest proportion of clay particles, and the loam soil has the most even distribution of sand, silt, and clay particles.
