Q. What are the tectonic plates?
Ans. Do you think that something can actually move you without your permission? You will be puzzled to hear that Lithosphere, the part of the land over which humans live, made of Earth’s crust and mantle is a continuously moving layer of Earth. The lithosphere is divided into big chunks of landmass called Tectonic Plates; which makes the actual movement possible. These plates can be bigger than even a continent.
