Which of the following statements regarding red soil is false?a)Red so...
Red soil is a type of soil that is commonly found in many parts of the world. It is characterized by its reddish color, which is a result of the presence of iron oxide. Red soil is known for its fertility and is often used for agriculture.
a) Red soil develops on crystalline igneous rocks: This statement is true. Red soil is formed from the weathering of rocks, and one of the primary sources of red soil is the weathering of crystalline igneous rocks. These rocks contain minerals such as feldspar and mica, which contribute to the formation of red soil.
b) Yellow and red soils can only be found in mutually exclusive regions: This statement is false. Yellow and red soils can be found in various regions, and their presence is determined by factors such as climate, parent material, and topography. While red soil is commonly found in tropical and subtropical regions, yellow soil can also be found in these regions as well as in temperate regions.
c) Red soil changes color when it occurs in a hydrated form: This statement is true. Red soil can change color when it occurs in a hydrated form. When red soil becomes saturated with water, it can appear darker or even black in color. This change in color is due to the water content and the alteration of iron oxide minerals.
d) None of the above: This statement is false. As explained above, statement b is false, so the correct answer is option 'B'.
In conclusion, the false statement regarding red soil is that yellow and red soils can only be found in mutually exclusive regions. Yellow and red soils can both be found in various regions, and their presence is influenced by climate, parent material, and topography. Red soil develops on crystalline igneous rocks, and it can change color when it occurs in a hydrated form.
Which of the following statements regarding red soil is false?a)Red so...
Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern parts of the Deccan plateau. Yellow and red soils are also found in parts of Odisha, Chhattisgarh, southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats. These soils develop a reddish colour due to diffusion of iron in crystalline and metamorphic rocks. It looks yellow when it occurs in a hydrated form.
