Plate Tectonics
Studying Plate Tectonics
| Question | Answer |
|---|---|
| Boundary of two plates moving away from each other | Divergent |
| Boundary of two plates moving towards each other | Convergent |
| Boundary of two plate slide past each other | Transform |
| Area where the denser plate moves under the lighter plate as they converge | Subduction zone |
| Supercontinent that broke apart and formed the modern day continents | Pangaea |
| Theory that Earth’s crust are broken into sections (plates) that slowly move and interact with each other at their boundaries | Plate Tectonics |
| Hypothesis that the continents were once joined to form a supercontinent which broke into pieces and the continents drifted to their present day positions | Continental Drift |
| Special case to explain the creation of isolated islands in the middle of a plate is known as this | Hotspots |
| Driving force of the movement of plates that occurs with the heating and cooling of magma in the mantle | Convection cell |
| Section of the Earth which mainly consists of solid iron and nickel | Inner core |
| Section of the Earth which consists of superheated iron and nickel in a liquid state | Outer core |
| Section of the Earth with consists of liquid magma that flows with the consistency of asphalt | Mantle |
| Section of the earth that most life resides upon | Crust |
