Earthquake | A shaking of the Earth's crust caused by sudden tectonic movement. |
Fold Mountains | Mountains formed by the Earth's movement. |
Mantle | The molten rock that surrounds the core. |
Margin/Boundary | The line between two plates (two plates can move towards each other, away from each other of slide side by side). |
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). |
