Question

How many primary tectonic plates make up the surface of Earth?

Answer 1

There are about 7 or 8 primary tectonic plates. The lithosphere is made of about a dozen plates. The plates fit together like the pieces of a jigsaw puzzle. However, the plates can move. This causes earthquakes, volcanoes, and mountains to form.

Hope it helps

Answer 2

There are 15 to 20 primary tectonics that make up the surface of Earth. They are called Lithosphere.
