Q- Differentiate between
a). Converging and Diverging Tectonic Plates.
Answer- Converging Tectonic Plates:
1. The tectonic plates which moves towards each other or tries to converge are known as Converging Tectonic Plates.
2. These plates collide or crumble or one of them slides under the other while moving toward each other or while converging.
3. Converging Tectonic Plates causes folds.
Diverging Tectonic Plates:
1. The tectonic plates which moves away from each other or tries to diverge are known as Diverging Tectonic Plates.
2. These plates do not collide or crumble or one of them slides under the other while moving away from each other or while diverging.
3. Diverging Tectonic Plates causes fractures in the crust.
b). Bhangar and Khadar:
Answer- Bhangar:
1. The old alluvial soil or older alluvium forms the bhangar. This form a large part of the Northern plains.
2. They lies above flood plains of rivers.
3. Form a terrace like feature.
4. The main demerit of Bhangar is that it is less fertile as compared to Khadar.
Khadar:
1. The new alluvial soil or younger deposits of the flood plains is known as Khadar.
2. They are low-lying next to the river.
3. Khadar contains calcerous deposits locally known as Kankar.
4. It is more fertile than Bhangar.
c). Western Ghats and Eastern Ghats:
Western Ghats:
1. Western Ghats mark the western edges of the Deccan plateau.
2. Continuous can be crossed through the passes only.
3. The Western Ghats experiences orographic rain, mostly in summer due to the summer monsoons. The climate is hot and most at Western Ghats.
4. The soil in Western Ghats is highly fertile as is very fit for rice, spices, rubber and fruits like- coconuts, cashew nuts e.t.c. .
5. The elevations of Western Ghats is about 900-1600 meters.
Eastern Ghats:
1. Eastern Ghats mark the eastern edges of the Deccan plateau.
2. Discontinuous, irregular and dissected by rivers draining into the Bay of Bengal.
3. The Eastern Ghats receives rain mostly in winter through north-eastern monsoon. However this region experiences less rain as compared to Western Ghats.
4. The soil in Eastern Ghats is not highly fertile as compared to Western Ghats but is very fit for rice, ground nuts, cotton, tobacco, coconuts e.t.c. growth.
5. The elevations of Eastern Ghats is less than 600 meters.
