Question

Discribe the process of soil formation and state on which basis these are classified?​

Answer 1

1. Parent Rock material. = underlying rocks which contain minerals and make up the bulk of the soil are called the parent rocks. parent rocks influence the colour, texture, chemical properties, minerals content and permeability of the soil.

Answer 2

Soil forms through the interaction of the major soil-forming factors--parent material, climate, vegetation and animal life, relief, and time.
Climate and vegetation are the active forces in soil formation. Relief modifies the effects of climate and vegetation, mainly through its influence on runoff and temperature. Parent material also affects the kind of profile that forms. Time is needed for changing the parent material into soil. Usually a long time is required for the formation of distinct horizons.

And hence the soil is formed mainly from rocks and minerals.
