Question

Clear cutting large areas of trees at one time:

Answer 1

Answer:

Option (D)

Explanation:

The clear-cutting down of large and small trees is commonly known as the deforestation process. It is usually done by humans, so they are often considered as an anthropogenic activity.

There are various impacts that can be caused due to the deforestation process. It often reduces the amount of rainfall, as the area lacks in the moisture content. The incoming heat energy from the sun warms the area and dries up the land by absorbing the lesser amount of water, if any, present in the soil. Soil erosion takes place commonly and rapidly, thereby increases the temperature of the land areas.

Thus, all the above-given options are correct and so the correct answer is option (D).

Answer 2

All of the statements are true about the consequences of clear cutting large areas of trees at one time.

Explanation:

When a large area of trees is clear cut at once, or in a very short period of time, it brings significant changes to the area. The consequences are mostly environmental, and they affect all the living organisms in the area, including the humans. It is not only the living organisms that are affected though, but also the physical features and characteristics of the area. The climate too experiences changes very quickly, which are often negative changes.

• The removing of the trees from an area exposes the land to direct sunlight, which results in higher temperatures.
• The higher temperature of the land contributes to drying up of the land, thus gradually making the land semi-arid or arid.
• Because the land will be drier and warmer, the air masses will be dry and warm, thus the rainfall will sharply decrease in the area.
• Another major change will be that the rate of erosion will increase significantly, as the soil will not have its natural protection from the trees, so it will rapidly erode.
