None of these
Answers
Answer:
Polythene bags are not involved in soil formation. However, plastic bags are threat to environment, because these bags are non-degradable, i.e., do not decay and thus, do not lead to soil formation.
Answer:
Temperature C is not an agent of soil denudation.
Explanation:
Denudation means Soil erosion. In other simpler words denudation is termed as loss of uppermost soil and making the soil weak. The loss of uppermost layer of soil washes away the fertile soil and thus makes the soil unfit for plants to grow. Soil denudation is one of the major cause for soil pollution. Water and Air can cause denudation if soil. Water during floods or over raining washes away the topmost fertile soil along with them. On the other hand, Air mainly heavy winds makes soil to flew away. Temperature makes soil hot or cold but has nothing with loss of uppermost layer of soil. Thus we can justify that the answer in the above options is C. Temperature.
