Describe briefly the role of internal and external forces in the formation of various types of landforms?
Answers
Answer:
The internal forces act from within the earth to the surface and lead to earthquakes and volcanic eruptions. They cause upliftment of the earth crust and give rise to mountains and plateaus. The external forces act as running water, wind, ice, waves and wear down the highlands into lowlands by depositing materials.For example, wind and water are the external forces which cause weathering and denudation of land. Internal forces act under the earth's surface and result in the change of landforms.Landforms on the earth are a result of two processes. The first, or the internal process leads to the upliftment and sinking of the earths surface at several places. For example, Mountains and Trenches formation. The second, or the external process is the continuous wearing down and rebuilding of the land surface.
