Question

Write a note on the internal and external processes of Earth.

Answer 1

Geological agents and processes are classified as internal and external.

Internal geological agents and processes are drive by the heat that is stored in the Earth's interior. They usually occur far from the surface. The main internal geological agent is the movement of the lithospheric plates. The most evident and catastrophic events caused by this movement are Earthquakes and volcanic eruptions. Others are the movement of the continents, the opening of new seas and the closing of old ones, or the formation of mountain ranges.
It can be said that internal geological processes build the Earth's relief.

External geological agents and processes affect the Earth's surface. They are powered by solar energy. External processes shape the relief created by internal processes. External agents carry out this process: water, ice, wind, atmosphere and human beings. They include all the changes that alter or wear down the rocks and deposit materials resulting from erosion.

Answer 2

Solution:

Internal processes occur due to the internal heat of the Earth’s interior.

The movement in the lithospheric plate is the biggest example of internal processes.

Volcanoes, earthquakes are all example of internal process caused by the disturbance in the earth’s layer.

External processes however affect the surface of the earth.

It shapes the relief feature of the earth formed due to internal processes.

Formation of mountain range is its example.
