One of the following factors does not lead to soil formation in nature:
The correct option is D the polythene bags
The correct option is D:
Explanation for the correct answer:
- Soil formation is the process of breakdown and degradation of bigger rocks into smaller particles called soil.
- This occurs through weathering carried out by physical, mechanical, and chemical changes.
- Various agents of weathering include solar radiation, strong winds, heavy rain, etc.
- The polythene bags do not degrade or mix with other particles hence they cannot form soil.
Explanation of the incorrect answer:
Option A:
The Sun's rays fall on the rocks during the daytime making them expand and condense during the night. Unequal and unsynchronised expansion and condensation cause the rock to crack and break down into soil particles.
Option B:
Water enters the cracks that are formed in the rocks due to the sun's heat. This water freezes as temperatures fall and leads to cracks. Eventually, the soil is formed by this repeated cycle.
Option C:
The wind carries small rocks and gravel and deposits them in new places leading to the formation of soil.
The final answer is Polythene bags.
