Social Studies CASE BASED QUESTIONS [4M - GEOGRAPHY]

Read the passage given below and answer the following questions:
India is fortunate to have fairly rich and varied mineral resources. However, these are unevenly distributed. Broadly speaking, peninsular rocks contain most of the reserves of coal, metallic minerals, mica and many other non-metallic minerals. Sedimentary rocks on the western and eastern flanks of the peninsula, in Gujarat and Assam have most of the petroleum deposits. Rajasthan with the rock systems of the peninsula, has reserves of many non- ferrous minerals. The vast alluvial plains of north India are almost devoid of economic minerals. These variation exist largely because of the differences in the geological structure, processes and time involved in the formation of minerals.
Q.1. What is the reason for uneven distribution of minerals in India?
Q.2. Where are Petroleum deposits found in India?
Q.3. Which regions have the highest amounts and which contain lowest deposition of economic minerals?

Read the text given below and answer the following questions.
We have shared our land with the past generations and will have to do so with the future generation too. Ninety five percent of our basic needs of food, shelters and clothing are obtained from land.
Human activities have not only brought about degradation of land but have also aggravated the pace of natural forces to cause damage to land. Some human activities such as deforestation, overgrazing, mining and quarrying too have contributed significantly and land degradation.
Mining sites are abandoned, after excavation work is complete, leaving deep scars and traces of over burdening. In states like Jharkhand, Chhatisgarh, M.P. and Odisha, deforestation due to mining have caused severe land degradation. In states like Gujarat, Rajasthan, M.P. and Maharashtra overgrazing is one of the main reasons for land degradation. In the states like 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.
