Plate Tectonics: An Introduction

How many tectonics plates are there?

a) 12

b) 4

c) 18

d) 9

Answer

The correct answer is: c) 18

Plate tectonics is a scientific theory that explains the movement of the Earth's lithosphere, which is divided into several tectonic plates. These plates float on top of the semi-fluid asthenosphere beneath them.

There are a total of 18 major tectonic plates on Earth's surface. These plates vary in size and shape, and they interact with each other at their boundaries, causing geological phenomena such as earthquakes, volcanic eruptions, and mountain formation.

The movement of tectonic plates is driven by the heat generated from the Earth's core, creating a dynamic system that constantly shapes the planet's surface over millions of years.
