Model Answer

Black soil develops deep cracks during hot weather. This is beneficial because the cracks allow proper aeration of the soil — air circulates into the deeper layers, improving soil health and making it suitable for plant growth.

Explanation

The answer is directly from the textbook line: "They develop deep cracks during hot weather, which helps in the proper aeration of the soil." Examiners expect two things here — naming the behaviour (cracking) and stating the benefit (aeration). Both parts are needed to score full 2 marks. Do not confuse this with moisture retention, which is a separate property of black soil.
