Questions from K K Gupta and Stalin Malhotra Solutions for Chapter: Soil, Exercise 2: Let's revise with Hints & Solutions
_____ soil has finest of all soil particles.
B-horizon is the most fertile part of the soil.
Overgrazing leads to soil erosion.
A fertile soil is rich in humus.
Bedrock lies above the subsoil.
Topsoil is soft, porous and retains water.
Read the passage given below.
Removal of forests, trees or other vegetation for commercial use, housing, agriculture or firewood without replanting is deforestation. It is one of the factors for global climate change. Trees absorb carbon dioxide. They produce oxygen and maintain the amount of moisture in it by releasing water vapour into the atmosphere. They also prevent soil erosion by holding the soil tightly. Excessive cutting of trees may convert a forest into barren land and also increase flooding. Deforestation has also led to the loss of species.
The World Wildlife Fund has reported that much of the logging industry that contributes to deforestation is done illegally. Natural Resources Defence Council describes deforestation as ‘an ecological trauma that has no precedent in nature except for a major volcanic eruption.’
Answer the following questions:
Which of the following is not an effect of deforestation?
