Master GCSE Geography Plate Tectonics using simple revision notes, key facts and practice questions — all generated by AI for your exam.
Plate tectonics is the theory that explains how the Earth's outer shell, or lithosphere, is divided into several large plates that move and interact with one another. This movement causes various geological phenomena such as earthquakes, volcanic eruptions, and the formation of mountains.
Key Concepts
- 1The Earth's lithosphere is divided into tectonic plates.
- 2Tectonic plates can move apart, collide, or slide past each other.
- 3Earthquakes often occur at plate boundaries.
- 4Volcanoes are commonly found along convergent and divergent boundaries.
- 5The movement of plates is driven by convection currents in the mantle.
Simple Explanation
Plate tectonics is like a giant puzzle made of pieces called tectonic plates that float on the Earth's surface. These plates can move in different ways, like pushing against each other or pulling apart. When they move, they can cause earthquakes and create volcanoes. Understanding how these plates work helps us know more about the Earth's landscape and natural disasters.
