Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates. These plates float on the semi-fluid asthenosphere and interact at their boundaries, leading to geological phenomena such as earthquakes, volcanic activity, and mountain building.
Key Concepts
- 1The Earth's lithosphere is divided into tectonic plates.
- 2Tectonic plates move due to convection currents in the mantle.
- 3Plate boundaries can be divergent, convergent, or transform.
- 4Earthquakes and volcanoes are often found at plate boundaries.
- 5The movement of tectonic plates shapes the Earth's surface over time.
Simple Explanation
Plate tectonics is like a giant puzzle made of the Earth's outer layer, which is split into big pieces called tectonic plates. These plates move around slowly, and when they bump into each other or pull apart, they can cause earthquakes and volcanoes. This movement is driven by heat from inside the Earth, creating convection currents in the mantle. Over millions of years, these movements change the shape of the Earth's surface.
Memory Trick
“Remember 'D-C-T' for the types of plate boundaries: Divergent, Convergent, and Transform.”
