Write a note on the internal and external processes of Earth.

The forces acts form the interior of the earth to the earth's surface is known as an internal or endogenetic process. These forces are responsible for creating the landscape and topographic relief. Internal process ejects heat from the interior of the earth to the surface. Internal radioactivity is the principal source of power for this process. The plate tectonics, earthquakes, volcanoes are examples of the internal process.

The forced act on the earth's surface due to the natural agents such as water, glacier, wind, waves etc. is called an external processor exogenetic process. This process tears the landscape down into relatively low elevated plains.
