Plate Tectonics
Across
- 2. Two or more tectonic plates are pulling apart and new crust is formed
- 6. Tectonic plate that is composed of granite rocks where are lightweight materials such as quartz.
- 7. tectonics
- 8. The point on the surface directly above the earthquake origin.
- 9. Formation of new oceanic crust, which occurs through upwelling of magma at midocean ridges and subsequent outward movement on either side.
- 10. Two plates slide past each other in opposite directions
- 12. Movement of heat; hot materials rise and cool then fall back towards the heat sources in a circular motion.
- 13. Branch of science that studies earthquakes and relate phenomena
Down
- 1. Sudden and violent shaking of the ground that can cause massive destruction, as a result of plate movement of erupting volcano
- 3. Two plates come together, and one subducts under the other creating a long narrow depression on the seafloor.
- 4. Tectonic plate that is composed of heavy and dense material such as basalt.
- 5. Two or more tectonic plates are coming together and will form mountains and/or ocean trench with volcanic mountains.
- 9. Two or more plates come together and one plate sinks beneath the other
- 11. A mountain of hill that has a crater or vent that lava, rock fragments, hot vapor and gas are released from beneath Earth’s crust.
