Definitions:

Upwelling Mantle

Refers to the process where hotter, less dense mantle material ascends towards the Earth's surface, typically at mid-ocean ridges or hotspots.

Mantle Convection

Movement of mantle material in response to variations in density, especially those caused by differences in temperature.

Asthenosphere

A semi-fluid layer beneath the Earth's lithosphere on which the tectonic plates move, located in the upper mantle between approximately 100 and 250 kilometers deep.

Density

A measure of mass per unit volume of a substance, influencing how materials interact, such as floating or sinking in water.
