(iii) Western Ghats and Eastern Ghats
(i)The Earth’s crust is broken up
into several lithospheric or tectonic plates. These plates are
constantly moving atop the Earth’s mantle (semi-solid layer of
molten rocks). Based upon their motion, tectonic plates are referred
to as converging or diverging. Converging
tectonic plates move towards each other
and form convergent boundary. Diverging
tectonic plates move away from each
other and form divergent boundary.
(ii)Bhangar
is the terrace-like feature present above the flood plains of the
rivers. It is composed of older alluvium. It is the largest part of
the Northern Plain. The soil of this region contains calcerous
deposits locally known as kankar.
The
newer, younger deposits of the flood plains are called khadar.
This region is very fertile as it gets renewed almost every year.
Hence, it is ideal for intensive agriculture.
