Well, it's made up of compressed rock. Another person asked this question and this is the answer: "The Earth's mantle, other than the uppermost hard, rocky layer, is composed of rock in a pliable solid state." Hope this helps and answers your question.
The lower mantle is primarily solid, although some areas may experience partial melting to create magma. The solid nature of the lower mantle is due to high pressure, which helps keep the minerals in a solid state despite high temperatures.
The lower part of the Mantle is liquid.
The mantle isn't 100% liquid because magma solidifies near the crust and becomes plastic in texture and not fluid but eventually cools down to form the lithosphere. Lower parts of the mantle are not liquid because the high pressure keeps rock from melting.
The upper mantle is solid, but it can behave in a ductile manner over long timescales under high temperatures and pressures. This allows for the slow flow of solid rock over millions of years, a process known as mantle convection.
It's only soft and plastic in that it is not as hard as the brittle rock of the crust and uppermost mantle.
No. The Earth's mantle is a ductile solid.
Magma
Both. The upper mantle is solid and the lower mantle is liquid.
Inner core (probably solid); outer core (probably liquid); mantle, crust.
solid
the lower mantle of earth is a solid
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
Solid.
Solid!
The lower mantle is primarily solid, although some areas may experience partial melting to create magma. The solid nature of the lower mantle is due to high pressure, which helps keep the minerals in a solid state despite high temperatures.
Liquid I Think
The lower part of the Mantle is liquid.
