Fascinating Fact:
Tectonic plates move slowly over the mantle and their interactions create many major landforms, such as mountains, ocean trenches, and rift valleys.
In GCSE Geography, landforms and tectonic plates are studied together to explain how the Earth’s surface is built and reshaped. Pupils learn how plate boundaries create mountains, volcanoes, trenches, and rift valleys, and how these landscapes influence settlement, hazards, and economic activity.
Key Terms
- Tectonic plate: A large, rigid slab of the Earth’s crust and upper mantle that slowly moves over the mantle.
- Mantle: The hot, semi-solid layer of rock beneath the crust that allows plates to move.
- Rift valley: A long, steep-sided valley formed when the Earth’s crust pulls apart along a fault or plate boundary.
Frequently Asked Questions (Click to see answers)
What are tectonic plates in GCSE Geography?
In GCSE Geography, tectonic plates are huge slabs of the Earth’s crust and upper mantle that move slowly over the mantle. Their movement creates landforms and causes earthquakes and volcanoes.
How do tectonic plates create landforms like mountains and trenches?
When plates collide, rocks are pushed upwards to form fold mountains. When one plate sinks beneath another, deep ocean trenches form. At diverging boundaries, rifting creates valleys and mid-ocean ridges.
How do people use landforms created by tectonic plates?
People farm on volcanic soils, build reservoirs in rift valleys, use mountain areas for tourism and hydroelectric power, and exploit minerals found in tectonic zones, despite the natural hazard risks.
