Lithosphere | The upper part of the mantle and the crust |

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 |
