Because planet earth was liquid when it first formed according to scientists. But the crust solidified first before the others.
it isn't it is just a little liquidy but quite solid the only layer made out of liquid is the outer core.
The Earth's core is liquid because of the great heat down there, which is generated by the immense pressure of all the Earth's other layers which press in on it.
The lower part of the Mantle is liquid.
The outer core of the mantle can be liquid.
It is the ability of the mantle (solid) to flow like liquid.
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. Sanjida Ahmed 752/753
solid
The lower part of the Mantle is liquid.
The outer core of the mantle can be liquid.
Both. The upper mantle is solid and the lower mantle is liquid.
the lower mantle is a soild.
The core is solid metal surrounded by liquid metal, the mantle is liquid rock.
Liquid I Think
It is the ability of the mantle (solid) to flow like liquid.
No. The Earth's mantle is a ductile solid.
