Hotspot : These are the volcanic regions which are fed by the mantle layer of an earth.  Due to high temperature and low pressure in mantle of an earth leads to the melting of the rocks and this molten form of rock is known as magma. This magma rises through cracks and erupts out from volcanoes.

Accretion : A process of addition of a material to a tectonic plate or a landmass.

Fault : It is a crack in an earth crust.They linked with or form , the boundaries present between the earth's tectonic plates.

Mid-Ocean ridge: An elevated region on an ocean floor or we can say underwater mountain range formed on the ocean floor by the movement of tectonic plates.
