What part of the mantle is still a solid but flows like a thick heavy liquid?

What part of the mantle is still a solid but flows like a thick heavy liquid?

The asthenosphere is the hot, weak, inner part of the upper mantle. Although it is solid, it can flow like a thick, heavy liquid.

Which layer can flow like a thick fluid?

The mantle is the second layer of Earth. The upper portion of the mantle is mostly made of solid rock just like the crust above, but some of the upper mantle is semi-molten and able to flow like a thick, gooey syrup.

What part of mantle is liquid?

outer core
In the upper mantle, the silicates are generally solid but localized regions of melt exist, leading to limited viscosity. In contrast, the lower mantle is under tremendous pressure and therefore has a lower viscosity than the upper mantle. The metallic nickel–iron outer core is liquid because of the high temperature.

Which part of the mantle is thicker?

The lower mantle is hotter and denser than the upper mantle and transition zone. The lower mantle is much less ductile than the upper mantle and transition zone.

Which word best describes the hot weak inner part of the upper mantle which can flow?

The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. The lithosphere rides on the asthenosphere.

What are the two parts of Earth’s interior that make up the lithosphere?

The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure.

Which layer is a liquid?

The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth’s interior.

Is the mantle considered to be made of liquid?

The Earth’s mantle, on which the crust is lying on, is not made of liquid magma. The Earth’s mantle is mostly solid from the liquid outer core to the crust, but it can creep on the long-term, which surely strengthens the misconception of a liquid mantle. Courtesy of the U.S. Geological Society.

What is the thickness of upper mantle?

The thickness of the upper mantle is about 640 km (400 mi). The entire mantle is about 2,900 km (1,800 mi) thick, which means the upper mantle is only about 20% of the total mantle thickness.

Is the mantle is in a liquid state?

The Earth’s mantle, on which the crust is lying on, is not made of liquid magma. It is not even made of magma. The Earth’s mantle is mostly solid from the liquid outer core to the crust, but it can creep on the long-term, which surely strengthens the misconception of a liquid mantle.
