Lithosphere asthenosphere diagram
WebThe asthenosphere spreads in opposite directions from the center of the diagram, which causes the lithosphere above it to move apart, creating a ridge. On the outer edges of the convection cells, the lithosphere dives into the Earth, forming trenches. Note that the layers of the Earth are not drawn to scale in Figure 13.4. WebE. Lithosphere, asthenosphere. Step-by-step explanation. The figure provided is a schematic diagram of the upper 200+ km of the Earth's interior. The Earth's interior can be divided into several layers, based on their composition, density, and physical properties.

WebLayers of the Earth Diagram. Created by. Works by Shannon. Students read about the physical properties of the layers of the Earth and draw each layer based on those properties. Layers include - Crust, Mantle, Core, Lithosphere, Asthenosphere, Upper Mantle and Lower Mantle (Mesosphere), Outer Core and Inner Core. WebThe lithosphere is the rigid, outermost shell on Earth. It is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater. The outermost shell of a rocky planet, the crust, is defined on the basis of its chemistry and mineralogy.

WebThe Earth’s asthenosphere is also made up of reasonably solid peridotites. About 99% of the asthenosphere is solid rock, and the other 1% is a molten-like magma state. The asthenosphere is hot, and that heat makes it mechanically weak compared to the lithosphere.
