Explanation: Red soil is red in color because of the high content of Iron Oxide (Feo).

• It is a type of soil that develops in a warm, temperate, moist climate under deciduous or mixed forest.
• These are generally derived from crystalline rock.
• These soils develop a reddish color due to diffusion of iron in crystalline and metamorphic rocks. It appears yellow when it occurs in a hydrated form.
• Red soils are usually poor growing soils, deficient in lime, magnesia, phosphates, nitrogen, and humus and difficult to cultivate because of its low water holding capacity.
