Question

Quizplus · Accepted Answer

The asthenosphere is the layer of soft, plastic-like rock located beneath the lithosphere that allows for isostatic adjustments. This layer is able to flow and deform under pressure, which allows for the Earth's crust to adjust to changes in surface loads such as the melting of glaciers, and volcanic eruptions. The other choices, such as the inner and outer core, lower mantle, and Moho, are not associated with isostatic adjustments.
