Q24. Read the text given below and answer the following questions:
Mining sites are abandoned after excavation work is complete leaving deep scars and traces of over -burdening. In states like Jharkhand, Chhattisgarh, Madhya Pradesh and Orissa deforestation due to mining have caused severe land degradation. In states like Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra overgrazing is one of the main reasons for land degradation. In the states of Punjab, Haryana, western Uttar Pradesh,
over irrigation is responsible for land degradation due to water logging leading to increase in salinity and alkalinity in the soil. The mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust in the atmosphere. It retards the process of infiltration of water into the soil after it
settles down on the land. In recent years, industrial effluents as waste have become a major source of land and water pollution in many parts of the country.
Answer the following MCQs by choosing the most appropriate option
24.1: Which one of the following is the main cause of land degradation in Punjab? (1)
a) intensive cultivation

c) Kerala
d) Uttaranchal
24.4: How human activity mineral processing responsible for land degradation in India? (1)
a) Water logging leading to increase in salinity and alkalinity in the soil.
b) Overgrazing is one the main reason of land degradation
c) Grinding of limestone for cement industry and calcite generate huge quantity of dust in the atmosphere.

3)Gujarat
4)Overgrazing is one the main reason of land degradation
Read the text given below and answer the following questions: Mining sites are abandoned after excavation work is complete leaving deep scars and traces of over-burdening.
1. Major cause of land degradation in Punjab - Option (c)
The major cause of land degradation in states like Punjab, Haryana, and western Uttar Pradesh is over-irrigation. This leads to water logging, which increases salinity and alkalinity in the soil.
2. Overgrazing as the reason for land degradation - Option (a)
Overgrazing is the major reason for land degradation in states like Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra.
3. Mining as the reason for land degradation - Option (b)
Deforestation due to mining has caused severe land degradation in states like Jharkhand, Chhattisgarh, Madhya Pradesh, and Orissa.
4. Human activity mineral processing responsible for land degradation in India - Option (c)
Mineral processing like the grinding of limestone for the cement industry and calcite and soapstone for the ceramic industry generates huge amounts of dust in the atmosphere. It slows down the process of seeping of water into the soil after it settles down on the land.
