GEOLOGY

Detailed explanation-1: -The theory of plate tectonics (tek TAHN iks) states that pieces of Earth’s lithosphere are in slow, constant motion, driven by convection currents in the mantle. The theory of plate tectonics explains the formation, movement, and subduc-tion of Earth’s plates.

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: -The system of ideas behind plate tectonics theory suggests that Earth’s outer shell (lithosphere) is divided into several plates that glide over the Earth’s rocky inner layer above the soft core (mantle).

Detailed explanation-4: -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.
