CH 6 MAJOR LAND FORM OF THE EARTH

garben is an elongated block of the earth’s crust lying between two faults and displaced downwards relative to the blocks on either side, as in a rift valley.

In physical geography and geology, a horst is a raised fault block bounded by normal faults. Horsts are typically found together with grabens. While a horst lifted or remains stationary, the grabens on either side subside. This is often caused by extensional forces pulling apart the crust.

a mountain caused by faulting and uplifting or tilting — compare basin range.

 Fold Mountains, Block Mountains and the Volcanic Mountains.

Mountains may be arranged in a line known as range.

A mountain is any natural elevation of the earth surface. The mountains may have a small summit and a broad base. It is considerably higher than the surrounding area.

The surface is being lowered by the process of erosion and rebuilt by the process of deposition

The wearing away of the earth’s surface is called erosion.

External Processes (or) Exogenetic Processes The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains.

A proven way to improve your internal processes is to think about a product or service that you provide from the perspective of a customer. Imagine that they are standing outside your organisation looking in at the various steps required to deliver the product or service to them.
