Question

what are tectonic plates​

Answer 1

Answer:

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. Tectonic plates are broken pieces made of the Earth's crust or lithosphere. Another name for them is crustal plates. Continental crust is less dense, and oceanic crust is denser. These rigid plates can move in different directions, shifting constantly.
