Final answer:
Plate tectonics explains the movement of Earth's lithosphere plates and their interaction, responsible for various geological phenomena.
Step-by-step explanation:
Plate Tectonics
Plate tectonics is a scientific theory that explains how the Earth's lithosphere is divided into several large plates. These plates are not made up of asthenosphere, but rather they float on the semi-fluid asthenosphere layer beneath. The movement and interaction of these plates are responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountains.
For example, the Pacific Plate and the North American Plate meet along the San Andreas Fault in California, which is a transform boundary. The lithosphere plates are constantly moving and can collide, separate, or slide past each other, causing Earth's surface to change over time.
