Term | Definition |
---|---|
Earthquakes | Violent shaking of the ground, caused by the movement of tectonic plates. |
Mountains | Formed by tectonic plates pushing together along boundaries and forcing the ground upwards. |
Ocean Rifts | Formed by seafloor spreading, tectonic plates move away causing a rift. |
Volcanoes | Similarly formed to mountains -- but Magma becomes stuck in a chamber and eventually erupts. |
Boundaries | The place where two plates meet. |
Faults | Caused by stress between tectonic plates -- causes the rocks at the surface to break because of the stress. |
Plate Tectonics | The theory of continental drift, tectonic plates -- words like convergent, divergent, and seafloor spreading are used to describe parts of it. |
