| Mountain | A natural upward projection of the earth’s surface, higher and steeper than a hill. |
| Pressure | Force that builds up in the mantle or crust leading to volcanic eruptions or earthquakes. |
| Tectonic Plates | A large section of the Earth's crust. |
| Tremors | Small vibrations of the earth’s crust that increase in frequency and intensity before or after an earthquake (foreshocks and aftershocks). |
