Question

Give a geographical reason for the following:

Red soil is red in colour and its colour varies from yellow to brown.

Answer 1

The geographical reason for the red colour of red soil is the high content of iron oxide (ferric oxide) in the soil. When iron reacts with oxygen, it forms iron oxides, giving the soil its red colour. The colour can vary from yellow to brown depending on the specific composition and hydration of the iron compounds present, the amount of organic matter, and the degree of weathering in the soil.
