The mantle is primarily solid due to the high pressures and temperatures that keep its minerals in a solid state. However, it can flow like a liquid over geological timescales due to the presence of heat, which causes partial melting and the formation of a viscous, semi-fluid layer called the asthenosphere. This allows for slow, convective movement within the mantle, facilitating tectonic processes such as plate tectonics. The combination of solid-state properties and the ability to deform over long timescales enables this unique behavior.
The mantle is mostly solid, but it can flow slowly over long periods of time, behaving like a very viscous liquid. This movement is what drives plate tectonics on Earth.
It is a solid from the liquid outer core all the way to the crust
No. The Earth's mantle is a ductile solid.
The Moho, short for Mohorovičić discontinuity, is a boundary in the Earth's crust that separates the solid crust from the underlying mantle. So, the Moho is where the solid crust transitions into the solid mantle, but it is not a solid or liquid layer itself.

Both. The upper mantle is solid and the lower mantle is liquid.

the lower mantle of earth is a solid
The crust, mantle, and core. :)
Solid.
Solid!
Liquid I Think
The lower part of the Mantle is liquid.
The liquid core of Earth is surrounded by the solid mantle and crust. This liquid outer core is mostly composed of iron and nickel, and it is responsible for generating Earth's magnetic field through convection currents.
