Question

Looking into today's scenario, try to imagine the future in a world with increasing deforestation. Which of the following situation can happen when there is less number of trees?


  1. 1, 3, 4

  2. 2, 3, 4

  3. 1, 2

  4. 1, 2, 3


Solution

The correct option is B

2, 3, 4


Trees in the forest hold the soil firmly with their roots which bind with the soil particles and prevent it from erosion (Image 4).Trees also regulate strong winds and reduce dust storms. Forest acts as a natural absorber of rainwater and allows it to seep. When rainwater falls on leaves of trees and plants, it does not fall directly on the ground. It drips slowly on the forest ground and does not stagnate. Thus trees prevent flooding (Image 2).The roots hog the soil, a lot of trees and vegetation on the slopes slows down the speed of water flowing down the hill. The water that gets soaked in the ground gets soaked up by the trees & vegetation, so it does not become very soft as to be able to slide easily (Image 3).
