- 2. divergent boundary occurs when two tectonic plates move away from each other. ... Two plates sliding past each other forms a transform plate boundary
- 4. the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
- 5. results suggest that tectonic plates also need this type of lubrication to keep moving."
- 6. Rocks and Plate Boundaries. Intense igneous activity happens along divergent and some convergent plate boundaries.
- 9. Metamorphic rocks result from the forces active during plate tectonic processes.

- 1. Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.
- 3. Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other.
- 7. divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock).
- 8. of rock) that has formed from sediment deposited by water or air.
- 10. This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate
