Question

Red soil is red in colour. Give geographical reasons for it.

Answer 1

Hint: Red soil is a type of soil that forms in a warm, moderate, moist environment beneath deciduous or mixed woodland and has thin organic and organic-mineral layers, as well as a dark brown, leached layer that rests on an illuvium red layer. Weathering of old crystalline and metamorphic rock produces red soils in most cases. They get their name from their deep crimson colour.

Complete answer:
Red soil can also be reddish-brown or reddish yellow in colour. They are often poor growing soils that are deficient in nutrients and humus, as well as difficult to cultivate due to their limited water holding capacity. Red soil is a valuable resource.

Red soils are India's third-biggest soil type, encompassing over 350,000 square kilometres (10.6 percent of the country's total area) throughout the peninsula from Tamil Nadu in the south to Bundelkhand in the north, and Rajmahal hills in the east to Katchch in the west. On the south, east, and north, they encircle the red soils. In its hydrated state, it appears yellow.

The texture of red soil ranges from sand to clay, with loam being the most common. Porous and friable structure, lack of lime, kankar and free carbonates, and a limited amount of soluble salts are some of their other features.

Red soil can be any hue from red to brown, chocolate, yellow, grey, or even black. The hue of red soil is due to a high concentration of iron in the soil.

Note: Red soil is an important soil resource with significant implications for agriculture's long-term sustainability and economic growth. However, in recent years, China's red soil has deteriorated and is facing several dangers, including soil erosion, acidification, and pollution.
