Red and yellow soils: (a) Features: (i) These soils develop reddish colour due to diffusion of iron in crystalline and metamorphic rocks. It looks yellow in a hydrated form. (ii) They are highly porous and fertile when they are fine grained and deep. (b) Places: Red soil develops on crystalline igneRead more

(ii) They are highly porous and fertile when they are fine grained and deep.
(b) Places: Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern parts of the Deccan plateau. They are also found in parts of Orissa, Chhattisgarh, southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats.
Black soil: (a) Features: (l) This soil is black in colour. (ii) It is also known as regur soil. (iii) It is ideal for growing cotton and is known as block cotton soil also. (iv) lt is made of clayey material. (v) It can hold moisture. (vi) It is rich in soil nutrients such as calcium carbonate, magRead more

(iv) lt is made of clayey material. (v) It can hold moisture. (vi) It is rich in soil nutrients such as calcium carbonate, magnesium, potash and lime. (vii) lt is poor in phosphoric contents. (viii) lt develops deep cracks during hot weather which helps in the proper aeration of the soil. (ix) These soils are sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period.
(b) Places: It is found in Deccan trap Basalt) region spread over northwest Deccan plateau and is made up of lava flows. They cover the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh, and extend in the south east direction along the Godavari and the Krishna valleys.
(a) Alluvial soils are formed by the deposition of rivers. (b) The features of the alluvial soils are explained as below: (i) The alluvial soils consist of sand, silt and clay. (ii) These soils contain adequate proportion of potash, phosphoric acid and lime. (iii) These soils are ideal for the growtRead more

(b) The features of the alluvial soils are explained as below:
(i) The alluvial soils consist of sand, silt and clay.
(ii) These soils contain adequate proportion of potash, phosphoric acid and lime.
(iii) These soils are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.
(iv) Soils in the drier areas are more alkaline and need proper treatment and irrigation.
(v) These soils are of two types – old alluvial soil known as bangar and new alluvial soil known as khaddar.
(c) Places: These soils are found in the entire northern plains, Rajasthan, Gujarat (a narrow corridor), eastern coastal plains particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers.
(d) Bangar is old alluvial soil and has higher concentration of banker nodules than the Khadar (new alluvial soil). It has more fine particles and is more fertile than the bangar.
State two features of the cold weather season (winter).
(i) Days are warm and nights are cold. (ii) Frost is common in the north and the higher slope of the Himalayas experience snowfall.

What is the ‘burst’ of the monsoon?
Around the time of its arrival, the normal rainfall increases suddenly and continues constantly for several days. This is known as the burst of the monsoon.

How does temperature vary from place to place and season to season in India? Give example.
In summer the mercury occasionally touches 50° C in some parts of the Rajasthan desert whereas it may be around 20° C in Pahalgam in Jammu and Kashmir
