It is time to know in detail about the surface of the earth on which we live. We know that the surface of the earth is not a plain platform. It is distributed unevenly with a variety of landforms like mountains, hills, plateaus, plains, ravines, cliffs, etc. Why is the surface of the earth uneven? What makes changes in the earth’s surface? What process makes mountains and hills? The answer to all the questions above – Is geomorphic.
Geomorphic Process
The formation and deformation of landforms on the surface of the earth are a continuous process which is due to the continuous influence of external and internal forces. The internal and external forces causing stresses and chemical action on earth materials and bringing about changes in the configuration of the surface of the earth are known as geomorphic processes. Processes.
Endogenic forces
- Endogenic forces are those internal forces that derive their strength from the earth’s interior and play a crucial role in shaping the earth's crust.
- Examples – mountain-building forces, continent-building forces, earthquakes, volcanism, etc.
- The endogenic forces are mainly land-building forces.
Exogenic forces
- Exogenic forces are those forces that derive their strength from the earth’s exterior or originated within the earth’s atmosphere.
- Examples of forces – the wind, waves, water, etc.
- Examples of exogenic processes – weathering, mass movement, erosion, deposition.
- Exogenic forces are mainly land-wearing forces.
Exogenic forces can take the form of weathering, erosion, and deposition. Weathering is breaking rocks on the earth’s surface by different agents like rivers, wind, sea waves, and glaciers. Erosion is carrying broken rocks from one place to another by natural agents like wind, water, and glaciers.
