Question

Q.6) Give a geographical reason of the following:
1. Physical weathering more effective in arid and temperate regions.
2. The finer materials like clay absorbs water and becomes heavier and starts flowing.

(100 points + brainiest for correct answer)

Answer 1

Answer:

1.In arid climates, however, weathering processes move very slowly. Mechanical weathering will be the dominant process in arid climates; however, because of its reliance on chemical weathering, it will also be quite slow. Hydrolysis (also sometimes called hydration)causes most silicate minerals to turn into clays.

2.Clay soils absorb water more slowly than sandy ones do; when water is applied too quickly, it puddles or runs off before being absorbed. Clay soils are slow to dry out; plants that grow in them are particularly at risk of diseases and other problems that result from overwatering.
