The formation and deformation of earth's crust. The lithosphere is not a homogeneous unit. It is divided in to multiple plates. The internal heat process, the convection process affects the plate tectonics.
4. INTERNAL HEAT SOURCE
Dynamic Planet Earth itself is a Giant Heat Engine
Primordial Heat Accumulated During Earth Formation
Radioactive Heat- Isotopes Disintegration- Uranium, Thorium & Potassium
Equilibrium of Constructive & Destructive Heat
Convection and Conduction Process
5. PLATE TECTONICS
Convection causes slow mvt of Asthenosphere to Diff Directions and
Lithosphere Break to Multiple Plates
Greek- Tektonikos means Building & Construction. It is the study of the
Formation & Deformation of Earths Crust which results in large scale features
