Question

What is the theory that earths surface is composed of several rock plates that fit together like pieces of a puzzle

Answer 1

The theory you are referring to is known as **Plate Tectonics**. This scientific theory describes the Earth's outer shell, or lithosphere, as being divided into several large and small tectonic plates that float on the semi-fluid asthenosphere beneath them. These plates can move and interact in various ways, leading to geological phenomena such as earthquakes, volcanic eruptions, mountain-building, and the formation of oceanic and continental features. The concept of Plate Tectonics also explains how the continents have drifted over geological time, which is often illustrated using the metaphor of pieces of a puzzle fitting together.
