Is the asthenosphere molten
Witryna7 lut 2024 · The newly-detected molten rock layer is located about 150 km (93 miles) from the surface of our planet and is part of the asthenosphere, which sits under tectonic plates in the upper mantle. Hua et al . discovered a previously unknown layer of partly molten rock in a key region just below the tectonic plates. WitrynaThe 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. …

Witryna14 kwi 2010 · The asthenosphere is composed of very hot, ductile ultramafic rock and is believed to be roughly 5% molten. What type of matter is the asthenosphere? Matter in the Asthenosphere is in the molten ... Witryna7 lip 2024 · The asthenosphere is the more plastic, molten layer below the more rigid crust. Crustal blocks like tectonic plates ride across the asthenosphere, being pushed and pulled by the convection (rising hot, sinking cold). The heat transfer helps dictate plate tectonics.

It has the same chemical makeup as the mesosphere, but its physical qualities are different.
Witryna15 wrz 2024 · The asthenosphere is part of the upper mantle located below the crust of the earth. The asthenosphere boundary is primarily defined by temperature, and it starts when the crust heats up to 1300° C. WitrynaThe layer of the Earth that is rigid but molten is called the Mantle. The mantle is the thickest layer of the Earth, making about 84% of the Earth's volume. It is made of very hot, and dense rock. This rock layer flows like asphalt because of the temperature difference from the top and bottom of the mantle. ... The asthenosphere is the part of ...
Witryna5 sie 2024 · 1) The asthenosphere is a layer of semi-molten rock. The temperature is just below the melting point of rock, so it's too hot to be solid like the crust, but still too …
