EXTERNAL AND INTERNAL GEOLOGICAL PROCESSES

EXTERNAL AND INTERNAL GEOLOGICAL PROCESSES

The geological agents responsible for these processes are: waves, the internal heat of the Earth, or rivers.

The Earth's surface has been subjected to numerous changes and phenomena known as geological 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.

Internal 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.

External geological agents and processes

Internal agents and processes tend to lift and build the Earth's relief from the interior. External agents and processes tend to destroy and shape the Earth's relief.

THE ENGINE OF INTERNAL AND EXTERNAL GEOLOGICAL PROCESSES

Both internal and external geological agents need a source of energy to drive them so that processes can take place.
