Across
- 3. Is an area on Earth where two or more lithospheric plates collide.
- 4. Rising mantle material makes plates move away from the ridge
- 6. Dense plate, sinks, gravity pulls on the rest of the plate with a force.
- 7. Is the sudden release of strain energy in the Earth's crust, resulting in waves of shaking that radiate outwards from the earthquake source.
- 8. Is a three-dimensional surface or zone across which there is a significant change in the velocity (speed or direction) of motion of one lithospheric plate relative to the adjacent lithospheric plate.
- 9. Deep area in the ocean floor between two plates where subduction is occurring.
- 10. Occurs when two tectonic plates move away from each other.
Down
- 1. Is a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.
- 2. Is a fault along a plate boundary where the motion is predominantly horizontal.
- 5. One plate is being pulled down into the mantle.
