Answer 2

Answer:

3.

a) Tsunamis are also known as Tidal Wave, the displacement of large water volumes causes the seismic sea waves. The main reason of causing such displacement is the gravitational pull caused by the Sun or the Moon which aderwaterlso results into underwater explosions and glacier calvings..

b) The rugged and soaring heights of Himalayas is an active fold mountains. Through the borders of Bhutan, China, India, Nepal and Pakistan, Himalayas stretch. Around fifty years ago, the clash between the Indian plate and Eurasian plate caused the formation of the Himalayan mountain range and Tibetan plateau.

c) Molten magma is thrown out to earth's mantle. The type of internal movement is convection currents. The plates diverge due to the pressure created by the currents. This causes the magma to be thrown out to the earth's crust.
