Question

As part of a study of the effects of urbanization, local scientists have taken many data samples over the course of 20 years. The scientists detected increases in local soil erosion, carbon dioxide levels, and air temperatures. What most likely caused these changes?
A erosion of topsoil

B altered water flow

C deforestation of woodlands

D decreased water quality

Answer 1

Explanation:

deforestation of woodland

Answer 2

Answer:

Option (C)

Explanation:

In order to set up urbanization in a selected area, initially, a large number of trees are being cut down. This process is commonly known as deforestation.

The deforestation process has various impacts on the environment and the climatic condition at various places. Extensive cutting down of trees leads to the occurrence of rapid soil erosion, where the materials from the topsoil are entirely carried away by wind and water. Due to this, there occurs a high absorption of incoming solar energy that increases the temperature of that area.

In addition to this, trees are the main source from which the oxygen is provided. The absence of trees also leads to an increase in the amount of carbon dioxide because the carbon dioxide will not be absorbed by the trees and in return, it won't be able to provide us oxygen. Due to this, the amount of carbon dioxide also increases.

Thus, the above changes are caused due to the deforestation of woodlands.

Hence, the correct answer is option (C).
