The asthenosphere is solid upper mantle material that is so hot that it behaves like plastic and can flow. The lithosphere rides on the asthenosphere. The asthenosphere is solid but it can flow, like.
The characteristics of the asthenosphere are that it is composed of semi-fused and solid materials. The asthenosphere is responsible for the renewal and expansion of the ocean floor. Asthenosphere The.
What is Lithosphere? The 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.
The upper position of the mantle of the earth is called the asthenosphere which is a weaker zone. It is from this weaker zone the molten rock materials find their way to the surface. The molten rock.
The rocky outer layer of the Earth is known as the lithosphere. The lithosphere consists of seven or eight major plates along with many minor plates. The lithosphere is composed of seven or eight major.
These plates move horizontally over the asthenosphere as rigid units. A plate may be called the continental plate or oceanic plate depending on which of the two occupy a larger portion of the plate..
