Importance of asthenosphere
Witryna9 lis 2024 · This weak channel is commonly referred to as the asthenosphere, and its presence accounts for a number of important Earth observations, including isostasy (e.g., support for the uplift of large mountain ranges), the shape of the Earth's gravity field, the response of the Earth's surface to the removal of large ice sheets … Witryna1 cze 2024 · Where is the asthenosphere and why is it important? The asthenosphere is a layer of rock that is found underneath the crust of the Earth. The solid crust of the Earth and its rocky upper mantle (also known as the lithosphere) meet the lower layers of the mantle at the asthenosphere, making it an important part of the structure of the …
