A) It is very fertile
B) It contains lots of minerals
C) It has originated from volcanic eruption
D) It develops cracks in the dry season and loosened particles fall in the cracks.
Correct Answer: D
Solution :
Black soils have been formed by solidification of lava spread over large areas during volcanic activities in the Deccan Plateau over thousands of years ago. These soils get sticky as they swell when wet in rainy season. In dry and hot season moisture is evaporated and the soils develop cracks in which loosened soil particles get accumulated. Thus there occurs a kind of 'self ploughing' and this soil requires least tilling.
