GEOLOGY

Detailed explanation-1: -The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.

Detailed explanation-2: -plate tectonics – the theory that pieces of Earth’s lithosphere are in constant motion, driven by convection currents in the mantle.

Detailed explanation-3: -Tectonic shift is the movement of the plates that make up Earth’s crust. The Earth is made up of roughly a dozen major plates and several minor plates.

Detailed explanation-4: -A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

Detailed explanation-5: -Plate tectonics is the theory that explains the global distribution of geological phenomena. Principally it refers to the movement and interaction of the earth’s lithosphere.
