Definitions [2]

Define plate tectonics.

The lithosphere is divided into a number of huge slabs of rocks called ‘Tectonic Plates’. These tectonic plates are divided into major and micro plates. These plates float independently over the mantle.

The term tectonic plates is defined as massive, irregularly shaped slabs of solid rock, generally composed of both continental and oceanic lithosphere. These plates make up the earth’s crust and are constantly moving because they rest on the molten magma beneath them.

Briefly define Mechanical Metamorphism.

Mechanical metamorphism refers to the process where rocks are changed mainly by pressure without much heat. The intense pressure squeezes and rearranges the minerals in the rock, making them more compact and sometimes forming new structures, but without significant chemical change.
