Answer 1

Answer:

a: Tsunamis are caused due to sudden internal movements within the earth’s crust below the ocean floor that lead to earthquakes and volcanic eruptions.

Answer b: Himalayas are formed by compression that lead to folding of the softer rocks.

Answer 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.

Answer d: A rift valley is a linear-shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension, a spreading part of the surface, which is subsequently further deepened by the forces of erosion.
