Question 1
1 / -0

Fill in the blanks:
Black soil is also called __________ soil.

A
Black

B
Malnad

C
Summer

D
Black cotton

Solution

For growing cotton, black soil is suitable and is also known as black cotton soil. These soils are made of extremely fine material , i.e. clay. They are well-known for their moisture retention ability.
The correct answer is D .
Question 2
1 / -0

The soil found at the foothills of Himalayas is _________.

A
Alluvial soil

B
Mountain soil

C
Laterite soil

D
Red soil
Question 3
1 / -0

The most important crop grown in black soil is ________.

A
Jute

B
Cotton

C
Ragi

D
Paddy
Question 4
1 / -0

In areas getting more than 200cms of annual rainfall, which type of soil is found?

A
Black soil

B
Red soil

C
Laterite soil

D
Alluvial soil

Solution

Intensive leaching is the primary explanation for the formation of laterite soils. Owing to heavy tropical rainfall more than 200 cms and high temperatures, leaching occurs. Lime and silica are leached away as a result of high precipitation, and soils rich in iron oxide and aluminium compounds are left behind.
The correct answer is C .
Question 5
1 / -0

This soil is most extensively spread over vast areas in India ________.

A
Laterite soil

B
Alluvial soil

C
Red soil

D
Black soil

Solution

Alluvial soil is spread in most parts of India. These soils cover about 40 percent of the total area of the country. They are depositional soils, transported, and deposited by rivers and streams. Since India is a land of rivers therefore we have alluvial soil deposition in most of the areas.
Black soil is present in the deccan plateau of India, Laterite in the areas of high rainfall and high temperature, and Red soil in southern parts of Deccan plateau.
Question 6
1 / -0

The black cotton soil area is called ____________.

A
Deccan Trap

B
Peninsular Plateau

C
Peninsular Ghats

D
Brahmaputra Valley
Question 7
1 / -0

In list A, types of soils and in list B, places where they are available are given. Identify the group that is matched correctly.
LIST A LIST B
$$(1)$$ Alluvial soil $$(a)$$ Deccan Trap
$$(2)$$ Black soil $$(b)$$ Peninsular Plateau
$$(3)$$ Red soil $$(c)$$ Western Ghats
$$(4)$$ Laterite soil $$(d)$$ Brahmaputra Valley

A
$$1-d;2-b;3-a;4-c$$

B
$$1-b;2-c;3-a;4-d$$

C
$$1-a;2-b;3-d;4-c$$

D
$$1-d;2-a;3-b;4-c$$
Question 8
1 / -0

Black soil is suitable for growing cotton because _________________.

A
It is sticky in nature

B
It is formed from the disintegration of volcanic rocks

C
It has the capacity to retain moisture for a long period

D
It is rich in potash and nitrogen

Solution

Generally known as a rainfed crop, cotton. It is also used in areas where there is no guaranteed irrigation. Black soils will sustain water that is a very useful property for the growth of rainfed crops. The soil's texture helps the growth of cotton. Black soils are therefore more suitable for the growth of cotton.
The correct answer is C.
Question 9
1 / -0

Black soil contains fine clay particles and is very useful wherever rainfall is less because it is able to _____________.

A
Absorb moisture

B
Retain moisture

C
Release moisture

D
Retract moisture
Question 10
1 / -0

Laterite soil is formed in the regions where _________.

A
The rainfall is heavy

B
The temperature is very high

C
There is less rainfall and high temperature

D
Large amount of salt and phosphate are found

Solution

Under conditions of heavy rainfall, the laterite soil is formed. Due to alternate wet and dry cycles, they are the result of extreme leaching. Heavy rainfall leaches out all soluble materials, leaving behind a high proportion of residual (remaining), insoluble iron and aluminium oxides in the soil from the top layer of the soil. Laterite soil is considered such soil. It is built in regions that receive heavy rainfall.
The correct answer is A.
