Saline soils are formed by intense evaporation and are usually found in ______________.

  1. steppes

  2. deltas

  3. equatorial region

  4. tropical desert region

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Saline soils develop in arid and semi-arid regions, such as tropical deserts, where evaporation rates are extremely high and rainfall is minimal. As water evaporates rapidly from the soil surface, it leaves behind dissolved salts that accumulate in the upper soil layers. Regions with high rainfall, like equatorial zones, wash these salts away instead.

Which of the following is suitable for growing cotton?

  1. Sandy soil

  2. Clayey soil

  3. Black soil

  4. Alluvial soil

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Black soil, also known as regur soil, is highly clayey and has an exceptional capacity to retain moisture, which is ideal for the long growing season of cotton. It is also rich in soil nutrients like calcium carbonate, magnesium, and potash. While alluvial soil is highly fertile, black soil is specifically renowned as the best medium for cotton cultivation.

Of the following statements about the major soil types, the incorrect one is ______________.

  1. Alluvial soils are easy to plough

  2. Red soils are rich in phosphorus, nitrogen and lime content

  3. Laterite is typically a soil of tropical regions which receive heavy seasonal rainfall

  4. Black soil is highly retentive of moisture and very productive

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Red soils are formed by the weathering of crystalline and metamorphic rocks and are typically deficient in nitrogen, phosphorus, humus, and lime. Therefore, the statement claiming they are rich in these nutrients is incorrect. The other statements accurately describe the easy-to-plough nature of alluvial soils, the tropical wet climate origin of laterite, and the high moisture retention of black soils.

Alluvial soil is formed by deposits brought by ___________.

  1. Rivers

  2. Sea

  3. Small streams

  4. Canals

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alluvial soil is formed by the deposition of silt, sand, and clay brought down by running water, primarily rivers. As rivers flow from mountains to plains, they deposit these rich sediments along their banks and floodplains.

The soil that has very poor fertility status _______________.

  1. Alluvial soils

  2. Black cotton or regular soils

  3. Laterite soils

  4. Red soils

Reveal answer Fill a bubble to check yourself
C Correct answer
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. Humus content of the soil is low because most of the micro organisms, particularly the decomposers, like bacteria, get destroyed due to high temperature. Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers. These soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Odisha and Assam.

The most fertile soil is ______.

  1. Red soil

  2. Alluvial soil

  3. Laterite soil

  4. Mountainous soil

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated.
