2.) Answer the following questions in about 30 words.

Question:

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

Answer:

3 states having black soil are:

1.) Maharashtra

2.) Gujarat

3.) Madhya Pradesh

The crop which is mainly grown here is cotton.

Question:

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 the type of soil found in the river deltas along the Eastern Coast.

1.) Additionally, alluvial soil can be found in the eastern coastal plains, particularly in the Godavari, Krishna, Mahanadi, and Kaveri river deltas.

2.) Alluvial soil is deposited by three significant Himalayan river systems which are Brahmaputra, Ganges, and Indus.

3.) Alluvial soil makes up the entirety of India's northern plains.

4.) The most significant and extensively distributed soil is alluvial soil.

Three main features of Alluvial Soil are:

1.) Because they are more alkaline, alluvial soils in drier locations can be productive with irrigation and adequate care.

2.) The alluvial soil is incredibly productive.

3.) Numerous crops are grown in alluvial soil due to their high fertility.

Other features of Alluvial Soil are:

1.) Pulse crops, cereals, wheat, paddy, and sugarcane are among the crops that can be produced in alluvial soil.

2.) The amounts of potash, phosphoric acid, and lime in the alluvial soil are suitable.

3.) The higher portions of the river basin have coarse alluvial soil.

4.) Such soils are more prevalent in the Terai, Chos, and Duars piedmont plains.

5.) As we travel north toward the river valleys, soil particles appear larger.

6.) Alluvial soil has different ratios of clay, silt, and sand.

7.) Along with its components and particle size, alluvial soil is also classified according to its age.

8.) Alluvial soil is divided into Khadar (new alluvial soil) and Bangar (old alluvial soil) according to age.

9.) Khadar alluvial soil has more fine particles and is more fertile than bhangar.

10.) Compared to Bangar, Kanker nodules are more prevalent in Khadar soil.

Question:

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

Answer:

The following list includes the main methods that can be applied:

1.) Contour Ploughing

2.) Terrace Farming

3.) Grass is permitted to grow in the gaps between the crops. Strip cropping is the term for this technique.

Question:

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

Answer:

Biotic resource:

1.) These are materials derived from the biosphere.

2.) These materials are alive.

3.) Examples include human beings, livestock, plants, animals, and fish.

Abiotic resource:

1.) These materials are made of inanimate objects.

2.) Examples include water, metals, minerals, wind, and solar energy.

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

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

Answer:

Physical elements like terrain, climate, and soil types, as well as human factors like population density, technical advancements, culture, and customs, among others, affect how land is used. From state to state, the pattern of the net sown area varies substantially. In Punjab and Haryana, it makes up more than 80% of the entire area, while in Arunachal Pradesh, Mizoram, Manipur, and the Andaman Nicobar Islands, it makes up less than 10%. The country's forest area is much smaller than the target 33% of its total area, as stated in the National Forest Policy (1952). It was considered essential for the maintenance of the ecological balance. A part of the land is termed wasteland, and land is put to other non-agricultural uses. Wasteland includes rocky, arid, and desert areas, and land put to other non-agricultural uses include settlements, roads, railways, industry, etc. Continuous land use over a long period without taking appropriate measures to conserve and manage has resulted in land degradation.

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

Answer:

This is due to several factors.

1.) Resource overuse resulted from large-scale production.

2.) Resource exploitation increased as a result of technological development.

3.) Increased medical and health resources resulted in significant resource use.
