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

  1. Desert soil

  2. Laterite soil

  3. Red soil

  4. Regur soil

D Correct answer
Explanation

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.

Match the following.

Regions Soil Type
A. Malwa Plateau $1$. Alluvial
B. Dharwar Plateau $2$. Lateritic
C. Punjab Plains $3$. Red
D. Western Ghats $4$. Regur

  1. A-$4$, B-$3$, C-$1$, D-$2$

  2. A-$4$, B-$2$, C-$1$, D-$3$

  3. A-$3$, B-$1$, C-$4$, D-$2$

  4. A-$2$, B-$3$, C-$4$, D-$1$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Malwa Plateau is dominated by Regur (black) soil due to its volcanic origin. Dharwar Plateau features red soils, Punjab Plains consist of fertile alluvial soils deposited by rivers, and the Western Ghats experience heavy leaching, leading to the formation of lateritic soils.

Match the following.

A. Alluvial soil $1$. high land of soil of plateaus
B. Black soils $2$. on the periphery of plateaus
C. Red soil $3$. river basin sand coastal plains
D. Laterite soils $4$. deccan lava tract

  1. A-$3$, B-$4$, C-$2$, D-$1$

  2. A-$1$, B-$3$, C-$4$, D-$2$

  3. A-$3$, B-$4$, C-$1$, D-$2$

  4. A-$2$, B-$1$, C-$3$, D-$4$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alluvial soils are deposited by rivers and are found in river basins and coastal plains. Black soils are formed from weathered volcanic basalt in the Deccan lava tract, red soils are found on the periphery of the plateau, and laterite soils develop on high-altitude plateau areas.

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

  1. These vary from sandy loam to clay is texture

  2. These are generally rich in phosphorus but poor in potash

  3. These are usually fine grained

  4. There are by far the most fertile
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Alluvial soils are generally rich in potash but poor in phosphorus. Therefore, the statement claiming they are rich in phosphorus but poor in potash is incorrect.

Which of the following are true in respect of alluvial soil?
$1$. Generally confined to river basins.
$2$. It has been deposited by rivers.
$3$. It is rich in phosphorus and poor in potash.
$4$. It is the most fertile soil.

  1. I and II

  2. III and IV

  3. I, II and IV

  4. I, II and III

C Correct answer
Explanation

Alluvial soils are highly fertile depositional soils confined to river basins and coastal plains. However, they are chemically characterized by being rich in potash and poor in phosphorus, making statement 3 incorrect.

  • 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.

Which of the following is/are not the characteristics of red soils?
$1$. They are derived from weathering of old crystalline and metamorphic rocks.
$2$. They contain iron oxides.
$3$. They have high water retention capacity.
$4$. They have high nitrogen content.

  1. II and III

  2. Only III

  3. Only IV

  4. III and IV
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Red soils are porous and coarse, which gives them a very low water retention capacity. Additionally, like most Indian soils, they are deficient in nitrogen, humus, and phosphoric acid, making statements 3 and 4 incorrect.

  1. from the Himalayan rocks

  2. from the Peninsular rocks

  3. only from the rocks existing locally

  4. from material brought by the rivers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The soils of the Indo-Gangetic plains are alluvial soils, which are depositional in nature. They have been transported over long distances by rivers from the Himalayas and the Peninsular plateau, rather than being derived from local rocks.
