Earth's Movement and Creation of Landforms

Endogenic forces and its types

The 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 types

The 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 crust

Deformation 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.

definition

Process of creation of different landforms

The 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 movement

Broadly, we can group different landforms depending on elevation and slope as:
1. mountains
2. plateaus
3. plains

definition

Sudden movements of the earth

The 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 movements

Epeirogenic 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.
