INTERNAL AND EXTERNAL PROCESS

INTERNAL AND EXTERNAL PROCESS

These landforms are a result of two processes. You will be amazed to know that the ground you are standing on is slowly moving. Within the earth, a continuous movement is taking place.

You must have seen some of the landform features as shown in Figure 6.1 below. You will notice that the surface of the earth is not the same everywhere. The earth has an infinite variety of landforms. Some parts of the lithosphere may be rugged and some flat.

Internal process

The first or the internal process leads to the upliftment and sinking of the earth’s surface at several places.

External process

The second or the external process is the continuous wearing down and rebuilding of the land surface. The wearing away of the earth’s 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.
