| Question | Answer |

| Subduction | Relates to convection currents, gravity and rock density |
| Weathering | Is where the rain, acid rain or wind breaks big rocks into little rocks (sediments) |
| Erosion | Wind or Water carries sediments away to another place |
| Volcano | Erupting mountain which spits out lava |
| Lithosphere | The upper part of the mantle and the crust |
| Igneous Rocks | Rocks that come from the mantle of the earth, which is comprised of molten rock (lava) |
| Sedimentary Rocks | Rocks that are either made of eroded rocks or from coral reefs in the ocean. |
| Metamorphic Rocks | Rocks that have changed by heat and/or pressure |
| San Andreas Fault | A fault in California where the North American and the Pacific tectonic plates meet and slide past each other |
| Continental drift | Create mountains when plates move towards each other & is the movements of continents |
| Syncline | Folds which bend downwards |
| Anticline | Folds which bend upwards |
| Crust | The top layer of the Earth |
| Convection currents | Heat currents within the mantle - they make the tectonic plates move |
| Normal Fault | When forces act in different directions and one part slips downwards |
| Reverse Faults | Pushed together and one part pushes upwards |
