Earth's Movement and Creation of Landforms
Endogenic forces and its typesThe forces relating to or arising from the interior of the earth are called endogenic forces. They are of two types- diastrophic and sudden movements.
Sudden movements and its typesThe sudden movements bring about instant changes on the surface of the earth. These movements are of two types- Volcanoes and Earthquakes.
Movements of the Earth's crustDeformation within the earth's crust producing structural landforms like mountains, plateaus, rift valleys, basins, etc. are known as the result of movements of earth's crust.
Process of creation of different landformsThe landforms are a result of two processes. Within the earth, a continuous movement is taking place. The first, or the internal process, leads to the upliftment and sinking of the earths surface at several places.
The second, or the external process, is the continuous wearing down and rebuilding of the land surface. The wearing away of the earths surface is called erosion. The surface is being lowered by the process of erosion and rebuilt by the process of deposition. These two processes are carried out by running water, ice and wind.
Classification of Earth movementBroadly, we can group different landforms depending on elevation and slope as:
Sudden movements of the earthThe earth's crust is continuously changing due to various geomorphic processes. These process includes the endogenetic and exogenetic processes. The endogenetic process mainly includes the internal process like plate tectonics, earthquake, volcanic eruptions etc. Earthquake and volcanic eruptions are called as the sudden movements, since they occur suddenly and causes considerable deformation over a short span of time.
Continent building or Epeirogenic movementsEpeirogenic movements occur towards the centre or from the earth's centre towards the crust. Because of these movements a vast part of the earth's surface is uplifted or gets subside. When a part of the earth's crust is uplifted , continents are formed. Therefore, these movements are called continent-building movements.
