Webb2 sep. 2024 · Plate tectonics, in brief, states that the Earth's surface is broken into plates. Each plate consists of slabs of lithosphere, the rocky outer layer of the Earth, that includes the crust and uppermost mantle. These lithospheric pieces move on top of the asthenosphere, a plastic layer within the mantle. Webb13 dec. 2024 · The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid. This allows the tectonic plates in the lithosphere to move around on the Earth’s surface. Which force from the asthenosphere is responsible for?

WebbThe special feature of the upper mantle is the asthenosphere. It is located just below the lithosphere and is made up of rock that is fluid and can move. Its chemical composition is very similar to the crust. I HOW THIS HELP. 2. what is the special feature of the upper mantle? The special feature of the upper mantle is the asthenosphere. Webb3 apr. 2024 · The Asthenosphere is made up of semi-plastic rock. Since the Lithosphere has a lower density, it floats on top of the Asthenosphere similar to the way in which an iceberg or a block of wood floats on water. The lower mantle below the Asthenosphere is more rigid and less plastic. Below the Mantle is the outer core.
WebbThe study of ultramafic rocks in Western Yunnan is of great significance for an understanding of the tectonic evolution of the Neo-Tethys Ocean. The zircon U–Pb data indicated that the Santaishan serpentinized pyroxene peridotite (SSPP) was formed 186–190 Ma, and the Yingjiang hornblende pyroxenite (YHP) was formed 182–183 Ma. … Webb15 juli 2024 · The rock of the mesosphere is harder than the rock in the asthenosphere, so it doesn’t flow as easily. The mesosphere is also hotter than the asthenosphere because it is closer to the center of the Earth. Occasionally, rock from the asthenosphere will enter the mesosphere, but this doesn’t happen often.

WebbAsthenosphere. Beneath the lithosphere is the asthenosphere. Tiny amounts of melted rock dispersed through the otherwise solid asthenosphere make the asthenosphere weak compared to the lithosphere.
