Question

How does the soil of the Ganga Yamuna plain differ from that of central Maharashtra (two differences)?

Answer 1

1. Origin and Formation: The Ganga-Yamuna plain's alluvial soil is an ex-situ (transported) soil generated by rivers depositing silt and sediments from the Himalayas. In contrast, the black soil of central Maharashtra is an in situ soil generated directly from the weathering and denudation of volcanic basalt rocks and lava flows from the Deccan Plateau.
2. Texture and Properties: Alluvial soil has a light, porous texture and lacks strong moisture-retention qualities. In contrast, black soil has a highly clayey and sticky texture with an amazing ability to hold moisture; when dry, it develops deep, visible cracks.
