Which layer of earth is made of Tectonic plates:

Tectonic plates are found in the outermost layer of the Earth. The outer layer has also been named the lithosphere. The word tectonic means plate movement. Tectonic plates are slabs of extensive rocks that diverge the Earth's crust. Due to the heat of the earth, these plates move inside, they sometimes come close to each other, and sometimes they move away from each other. Earthquakes are generated by the motion of tectonic plates.
