What is Geomorphic Process?

The geomorphic process means bringing about changes in the configuration of the Earths surface, due to physical stresses and chemical actions on materials present on earth. The physical and chemical action are due to endogenic and exogenic forces. There are 2 main geomorphic processes.

The below table gives the different processes under the exogenic and endogenic process

Exogenic Process Endogenic Process
  1. Weathering – Physical, Chemical, Biological
  2. Erosion/Degradation
  3. Transportation
  4. Deposition
  1. Volcanism
  2. Diastrophism
  3. Metamorphism
  4. Earthquake
  5. Landslides
  6. Faulting and Folding

Candidates would find this topic to be of importance while preparing for IAS Exam.

Which Process is an Internal Geomorphic Process?

The endogenic process is an internal geomorphic process. 

The main force behind this process is the energy emanating from inside the earth. This energy is mainly generated through the 3 processes given below.

  1. Primordial heat which exists right from the time earth was created.
  2. Rotational and tidal friction
  3. Radioactivity.

What are the Geomorphic Agents?

A geomorphic agent is a mobile medium which removes, transports and deposits earth materials. The examples of geomorphic agents are running water, glaciers, wind, waves, ocean currents, groundwater etc. All the movements occur due to gradients, from higher levels to lower levels or from high-pressure areas to low-pressure areas.

What is the difference between Geomorphic Process and Geomorphic Agents?

A geomorphic process is a force which applied on earth materials and affecting its configuration. A geomorphic agent is a moving medium which acquires, transports and deposits earth materials.

 

The above details would help candidates preparing for UPSC 2020.
