Question

What is "theory of plate tectonics"?
Explain in points.

Answer 1

Answer:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

The plates act like a hard and rigid shell compared to Earth's mantle.

The lithosphere includes the crust and outer part of the mantle.

Answer 2

Explanation:

Plate tectonics, theory dealing with the dynamics of Earth’s outer shell—the lithosphere—that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans
