B. Black soil	$$2$$. Contains aluminium compound
C. Laterite	$$3$$. Richest soils in the world
D. Terra Rosa	$$4$$. Formed in limestone

A-$$3$$, B-$$4$$, C-$$5$$, D-$$2$$, E-$$1$$

Question 2
1 / -0

The formation of laterite soil is mainly due to ___________.

A
weathering

B
erosion

C
leaching

D
deposition

Solution

Laterite has been derived from the Latin word ‘later’ which means brick. The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain.
Question 3
1 / -0

Which of the following types of soils have a marked capacity to retain water?

A
Desert soil

B
Laterite soil

C
Red soil

D
Regur soil

Solution

The black soils are made up of extremely fine i.e. clayey material. They are well-known for their capacity to hold moisture. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime.
Question 4
1 / -0

The red soils develop a reddish colour due to __________.

A
deforestation and over-grazing

B
the presence of potash and magnesia

C
tropical monsoonal climate

D
a wide diffusion of iron in ancient crystalline and metamorphic Jacks

Solution

Red soils develop a reddish colour due to diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form.
Question 5
1 / -0

The new alluvial deposits found in the Gangetic plain are known as:

A
bhabar

B
bhangar

C
khadar

D
terai

Solution

Alluvial soils are most widely spread and important soil. In fact, the entire northern plains are made of alluvial soil. According to their age alluvial soils can be classified as old alluvial (Bangar) and new alluvial (Khadar). Khadar has more fine particles and is more fertile than the bangar.
Question 6
1 / -0

The soil which is a mixture of sand, clay and silt is known as __________.

A
loamy soil

B
sandy soil

C
clayey soil

D
desert soil

B
Grey-brown soil found in Russia

C
Red, colour sticky soil, found in the Amazon area

D
Black soil found in northern Argentina

Solution

Black soils are also known as regur soils. Black soil is ideal for growing cotton and is also known as black cotton soil. This type of soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows.
Question 8
1 / -0

Which of the following soils is most suitable for cultivation of cereals?

A
Alluvial soils

B
Red soils

C
Laterite soils

D
None of these

Solution

Alluvial soils as a whole are very fertile. Mostly these soils contain adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.
Question 9
1 / -0

Match the following.
A. Alluvial Soil $$1$$. Cotton
B. Black Soil $$2$$. Rice
C. Brown Soil $$3$$. Tea
D. Red Soil $$4$$. Wheat

Solution
- Alluvial soils are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.
- Black soil is ideal for growing cotton and is also known as black cotton soil.
- Laterite soils or Brown soils are suitable for growing tea and coffee.
- Red soils are ideal for growing Rice, groundnut etc.
Question 10
1 / -0

Which of the following characteristics is not true of alluvial soils?

A
These vary from sandy loam to clay is texture

B
These are generally rich in phosphorus but poor in potash

C
These are usually fine grained

D
There are by far the most fertile

Solution

Alluvium is loose, unconsolidated soil or sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel.
