Plate Tectonics Theory
Theory of Plate Tectonics states that the earth's outer crust i.e. lithosphere is divided into plates (seven major and seven minors) that move over the asthenosphere, the molten upper portion of the mantle. Plate Tectonics is responsible for various geomorphological processes...

Isostasy & 6 Theories
The literal meaning of the Isostasy is the "stage of balance". It is the mechanical stability between the earth's crust( upstanding parts such as plains, plateaus, mountains, etc, and low-lying parts such as the ocean floor ) and mantle...
