  1. Alluvial soil

  2. Red soil

  3. Laterite soil

  4. Black soil


Correct Option: A

Mountain soil is best suited for the cultivation of tea, coffee and spices because it is rich in _________.

  1. Lime and magnesium carbonates

  2. Nitrogen and organic residues

  3. Ferric oxide and aluminium

  4. Clay particles

The black cotton soil area is called ____________.

  1. Deccan Trap

  2. Peninsular Plateau

  3. Peninsular Ghats

  4. Brahmaputra Valley


Correct Option: A

Water holding capacity of clayey soil is more than sandy soil because _____.
a) Space between clay particles is more
b) Surface of clay particle is more
c) Space between sand particle is more
d) Clay particle can absorb more water
Which one of the following alternatives is correct?

  1. A, D

  2. B, D

  3. B, C

  4. C, D


Correct Option: A
Explanation:

Clay soil have high water holding capacity. This is because the space between clay soil particles is higher making them possess more retention capacity. These soils can absorb more water.

The Arid soils are ______________ in colour.

  1. Red to brown

  2. Dark brown

  3. Dark red

  4. Pink


Correct Option: A

Which of the following statements is wrong?

  1. Laterite soils are black in colour.

  2. Mountain soils are shallow and immature.

  3. Black soils have ability to retain moisture for a long time.

  4. Alluvial soils are fertile.


Correct Option: A
Explanation:

Laterite is a soil and rock type rich in iron and aluminium, and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content.

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

  1. bhabar

  2. bhangar

  3. khadar

  4. terai


Correct Option: C
Explanation:

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.

The formation of laterite soil is mainly due to ___________.

  1. weathering

  2. erosion

  3. leaching

  4. deposition


Correct Option: C
Explanation:

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.
