Definitions:

Asthenosphere

The highly viscous, mechanically weak, and ductilely deforming region of the upper mantle of the Earth.

Decompression

The process of reducing pressure in a physical system, often leading to the release of dissolved gases or the formation of bubbles in a liquid.

Solid Mantle

The thick layer of solid rock between the Earth's crust and its liquid outer core, involved in plate tectonics and volcanic activity.

Earthquakes

Natural phenomena caused by a sudden release of energy in the Earth's crust, leading to ground shaking and, in some cases, causing great destruction.
