Webthe Earth that acts as a “lubricant” for the tectonic plates to slide over. The asthenosphere extends from 100 km depth to 660 km beneath the Earth's surface. Beneath the asthenosphere is the mesosphere, another strong layer. Crust and Mantle The crust is a chemically distinct layer at the surface of the Earth. Crustal material WebThe 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. It is ...

A soft, weak and plastic - like layer, the upper part of the mantle where lithospheric plates float and move. 10. WebThe asthenosphere is the zone of the earth which lies beneath the lithosphere. It is said to be hotter and more fluid than the lithosphere. We can say it extends from around 100 km to around 700 km beneath the surface of the earth. The rocks found in this zone which are mostly peridotite are quite solid in structure. greenlight app customer service

Reading: The Lithosphere and Asthenosphere Geology

The asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 and 120 mi) below the surface, and extends as deep as 700 km (430 mi). However, the lower boundary of the asthenosphere is not well defined. WebAlthough we sometimes refer to Earth’s plates as being plates of crust, the plates are actually made of lithosphere. Asthenosphere. The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere. Summary. The lithosphere is the brittle crust and uppermost ... WebThe asthenosphere is the layer below the lithosphere. Astheno- means lacking strength, and the most distinctive property of the asthenosphere is movement. Because it is … green light ant control
