Question

One of the following factors does not lead to soil formation in nature

• A. The sun
• B. Water
• C. Wind
• D. Polythene bags

Answer 1

The correct option is D

Polythene bags

The correct option is D.

Explanation for the correct option:

1. It is possible to define a non-biodegradable material as a kind of material that is a source of pollution and cannot be degraded by natural organisms.
2. Soil creation does not involve polythene bags.
3. However, because plastic bags are non-degradable, or do not break down, they pose a threat to the environment.
4. Long hydrocarbon chains make up the thermoplastic polymer known as polyethylene or polythene.

Explanation for the incorrect options:

Option A:

1. The rocks expand a little bit as a result of the sun's heat during the day.
2. Rocks have a tendency to compress at night when the temperature drops; as a result, cracks develop inside the rocks from successive simultaneous heating and cooling.
3. During the rainy season, this phenomenon is easily visible in hilly places.
4. When the sun comes out after a rain, it heats up the damp and chilly mountains, but they have a tendency to resist, which leads to mountain cracking.

Option B:

1. Another element that aids in the development of soil is water.
2. The fractures that form as a result of the heating and cooling of rocks are filled with water, which makes them wider.
3. Additionally, water removes the smaller rocks, causing them to collide and eventually break.

Option C:

A similar process is also used by wind, which moves sand from one place to another.

Final answer: One of the following factors that do not lead to soil formation in nature is polythene bags.
