the rock that can flow like a liquid is a mantle because the mantle has two parts. The upper part is the solid rock. The solid rock of the mantle is part is the lithosphere. Below the solid rock, the mantle rock has the ability to flow like a liquid. Most of the mantle is made up of rock that can flow.

Which part of the earth's mantle can flow like a thick liquid?
The asthenosphere, located in the upper part of the mantle, can flow like a thick liquid due to high temperatures and pressures that allow for the movement of rock over long periods of time.
What part of the mantle can flow like thick liquid?
The outer core of the mantle can be liquid.
What process causes liquid rock to move?
Liquid rock, or magma, moves through the process of convection within the Earth's mantle. Heat from the Earth's core causes magma to become less dense and rise towards the surface, while cooler, denser material sinks back down. This circular movement of hot magma is what propels the flow and movement of liquid rock beneath the Earth's surface.
How is it possible for mantle rock to flow?
Mantle rock is composed of a type of igneous rock peridotite which has a high iron and magnesium content. This rock is so hard and dense that it is not able to flow like a liquid. However due to the high temperatures and pressures that are present in the mantle it is possible for mantle rock to flow like a plastic-like material. This process is called "plastic deformation". Plastic deformation occurs when temperatures and pressures are high enough to cause the atoms in the rock to rearrange themselves. This rearrangement allows the rock to become more malleable and it is able to bend and flow like a liquid. This process is responsible for many of the changes that occur in the mantle such as convection currents and plate tectonics. The process of plastic deformation is not easily observed as it occurs deep within the Earth. However scientists have been able to determine the amount of pressure and temperature necessary to cause plastic deformation in mantle rock. It is estimated that temperatures must be at least 2000 degrees Celsius and pressures must be at least 10000 times the atmospheric pressure at sea level in order for mantle rock to flow. In summary mantle rock is composed of peridotite a type of igneous rock that is so hard and dense that it is not able to flow like a liquid.

What is the relationship for rock is to stone as puring is to cascading?
The relationship for rock is to stone is that a rock is a larger, natural mineral while a stone is a smaller, processed mineral. Similarly, pouring is to cascading in that pouring is a controlled flow of liquid while cascading is a more uncontrolled, continuous and often descending flow.
