Q. How is red soil formed?

1. Rainfall on black soil increases the pH value to give red colour
2. Deposition of alluvium and its silicates by winds and seawaves
3. Weathering of rocks like granite and gneiss

Q. Cotton is a crop that requires the following conditions to be grown:
1. Ample sunshine with fairly dry conditions.
2. Nutrient rich soil.
3. Soil which is well aerated.
4. Soil which can hold a lot of water.
Which soil is best suited for cultivating cotton?

1. Red Soil
2. Laterite soil
3. Black soil
4. Alluvial Soil

Q. This is a type of soil that develops in a warm, temperate, moist climate under deciduous or mixed forests, having thin organic-mineral layers overlying a yellowish-brown leached layer resting on an illuvial red layer.
It is generally formed from iron-rich sedimentary rocks. It is usually a poor growing soil, low in nutrients and humus and difficult to cultivate.
