Exploring the Theories of Plate Tectonics

Theories Behind Plate Tectonics

The theory of plate tectonics explains the movement of Earth's lithosphere, which is divided into large plates that float on the semi-fluid asthenosphere. These plates move due to convection currents caused by heat from the Earth's core. The movement of these plates causes geological phenomena such as earthquakes, volcanic eruptions, and the formation of mountain ranges.

Plate tectonics is a fundamental theory in geology, offering insights into Earth's past, present, and future.

Did You Know?

• Earth's lithosphere is divided into seven major tectonic plates, including the Pacific Plate and the North American Plate.
• The Mid-Atlantic Ridge is a divergent boundary where two tectonic plates are moving apart.
• Subduction occurs when one plate is forced beneath another, often causing earthquakes and volcanic activity.
• The theory of plate tectonics was developed in the mid-20th century, revolutionizing the study of geology.
