| Term | Definition |
|---|---|
| Lithosphere | Rigid outer part of earth including the crust and upper mantle |
| Aesthenosphere | Part of lithosphere which is mostly a plastic type of substance which is kept warm through the Earths radioactive decay. tectonic plates sit upon this layer |
| Magnetic field | Surrounds the Earth and protects it from solar winds |
| Hydrosphere | Includes all of the water that is present on Earth, both in the surface and air |
| Magnetosphere | The magnetic field |
| Atmosphere | Layer of gasses surrounding the planet, held close by the gravitational field, filters uv radiation, and keeps Earth warm through retention of thermal energy |
| Dynamo Effect | |
| Continental Drift | The hypothesis that the continents on earth are constantly moving away from each other, causing the oceans to expand wider |
| Subduction Zone | |
| Lamproites | |
| Transform Plate Boundaries | |
| Divergent Plate Boundaries | |
| Conduction | Transfer of heat energy through physical contact |
| Convection | Transfer of heat energy where it is similar to boiling water and works with only liquids and gasses |
| Radiation | Transfer of heat energy across vaccum of space, like the sun |
| Plasma | |
| Geomagnetic Reversals | |
| Coriolis Effect | |
| Ophiolite | |
| Global Warming | The "theory" that the Earth is constantly warming up due to the burning of fossil fuels being trapped in the atmosphere, causing a greenhouse effect |
| Plate Tectonics | |
| Doppler Effect | |
| Greenhouse Effect | |
| Mantle | |
| Seismograph | |
| Seismic Waves | |
| Sea-floor Spreading | |
| Xenolith |
