Senses and Usage:

Sense 1: Geology

In geology, the asthenosphere refers to the semi-fluid layer of the Earth's mantle, which allows the tectonic plates to move and interact.

Example sentence 1: The movement of tectonic plates is primarily caused by the convection currents occurring in the asthenosphere.

Example sentence 2: The asthenosphere plays a vital role in the process of plate tectonics, as it allows for the subduction of one plate beneath another.

Sense 2: Earth Sciences

The asthenosphere is a subject of study in earth sciences, particularly in understanding the dynamics and behavior of the Earth's interior.

Example sentence 1: Researchers use seismic waves to study the properties and characteristics of the asthenosphere.

Example sentence 2: The asthenosphere is responsible for the isostatic adjustments observed after the melting of glaciers.
