Q.2: Answer the following questions in about 30 words:

(i) Name three states having black soil and the crop which is mainly grown in it.

Answer:
The Black soils are black in colour. These are also known as regur soils.
This soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan Plateau. They cover the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh, and Chhattisgarh and extend in a south-east direction along the Godavari and the Krishna valleys. Black soil is ideal for growing cotton.

(ii) What type of soil is found in the river deltas of the Eastern Coast? Give three main features of this type of soil.

Answer:  Alluvial soil is found in the eastern coastal plan is particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers.
Three main features of this type of soil are as follows:

1. The alluvial soil consists of various proportions of sand, silt, and clay.

2. These soils are very fertile. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated.

3. These soils contain an adequate proportion of potash, phosphoric acid, and lime which are ideal for the growth of sugarcane, paddy, wheat, and other cereal and pulse crops.

iii) What steps can be taken to control soil erosion in the hilly areas?

Answer: In hilly areas, soil erosion can be controlled by contour which refers ploughing across contour-lines, making use of terrace farming techniques and using strips of grasses to check soil erosion by wind and water.

iv) What are the biotic and abiotic resources? Give some examples?

Biotic Resources: The resources which are obtained from the biosphere, from forest and the materials derived from them and have life are called Biotic Resources. For example, animals and plants including human beings.
Abiotic Resources: The resources which are composed of non-living things are called Abiotic Resources. For example, rocks, water, minerals, metals, wind, solar energy etc

Question 3. Answer the following questions in about 120 words.

i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?

Answer: i) The use of land is determined by both physical factors such as topography, climate, soil types as well as human factors such as population density, technological capability and culture and traditions.

1. Land resources in India are primarily divided into agricultural land, forest land, land meant for pasture and grazing, and waste land.
2. Wasteland includes rocky, arid and desert areas and land used for other non-agricultural purposes such as housing, roads and industry. According to the recent data, about 54% of the total land area is cultivable or fallow, 22.5% is covered by forests and 3.45% is used for grazing. The rest is wasteland, with traces of miscellaneous cultivation.
3. The land under forest has not increased since 1960–61 because in the post-independence era demand for more land to expand agriculture, mainly after Green Revolution, developmental works and infrastructural facilities, led to clearance of forests areas. Industrialisation and urbanisation also decreased the forest area. Thus, land under forest has increased by only about 4% since 1960-61.

ii) How has technical and economic development led to more consumption of resources?

Answer: Technical and economic development has led to more consumption of resources on account of various factors such as:

1. Technological development provides sophisticated equipment. As a result, production increases ultimately leading to consumption of more resources. Technological advancement leads to the conversion of more natural resources into useful resources thus the consumption also increases.
2. Technological development also leads to economic development. When the economic condition of a country rises, the needs of people also rise. It again results in more consumption of resources.
3. Economic development provides favorable environment for the development of latest technologies. It helps to make or convert various materials found around us into resources. Finally, it results in the consumption of newly available resources too.
