Yes. Tectonic plates are in fact mostly solid.
solid
The solid portion of the upper mantle which behaves as a brittle solid is known as the lithospheric mantle. This part of the upper mantle along with the crust forms tectonic plates.
The asthenosphere.
Lithospheric plates.
crust idiots
Tectonic plates.
its called tectonic plate
No, it is made of rock but it is made up of many plates that move around the place cause earthquakes. The crust is rock but it is not solid all the way around. The plates are called tectonic plates and if you search "tectonic plates of the world" it should tell you where they are and what they are made up of.
The lithosphere, which includes the uppermost portion of the mantle, forms the solid tectonic plates along with the crust. This layer is divided into massive plates that float on the semi-fluid asthenosphere beneath them.
The solid plastic layer upon which tectonic plates move is called the asthenosphere. It is located beneath the lithosphere and consists of partially molten rock that allows for the slow flow and movement of tectonic plates. This movement is driven by convection currents in the underlying mantle, facilitating the dynamic processes of plate tectonics.
The lithosphere, which includes the rigid outermost layer of the Earth's mantle, is responsible for the movement and formation of tectonic plates. These plates float on the semi-fluid asthenosphere below and interact with each other at plate boundaries, leading to processes like subduction and spreading.
The lithosphere is the layer along the crust that forms the solid tectonic plates. It consists of the crust and the upper part of the mantle and is broken into several pieces that move and interact with each other due to tectonic forces.
