Causes for Earthquake and Volcanic Activity

Tectonic Process: It is a process that acts over the years and creates major landforms. The Lithosphere is broken into several pieces known as Plates. These plates float on the soft layer of mantle .This is a partially molten material that causes the plates of the earth to move relative to each other. As the plates move they push, pull, slide, rise, sink , bend and break. This is called Tectonic process. The process is named after the Greek word "Tekton" which means a builder. Plate movement causes Volcanic activity and earthquakes specially at the margins of the plates.

The Lithosphere

The outermost solid surface layer of the atmosphere is called Lithosphere. It is also called Crust. The word lithosphere is derived from Greek word "lithos" which means "stones". The surface of the earth is not flat . It is uneven, with different kind of landforms - mountains, hills, valleys and plateaus. The crust is covered by the thin layer of soil .

Industries get vital minerals and other raw materials from the lithosphere .
