Plate Tectonics

4. an area on Earth where two or more plates collide
6. a strip of volcanoes mapped out on plate boundaries that looks like a circle
9. Tectonics a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements
10. can be a bone/imprinting of an extinct being/ plant from possibly millions of years ago
11. a mountain like land form, generally over a hotspot, that erupts molten rock
12. occurs when two tectonic plates move away from each other
14. heat traveling through an empty space
15. molten rock that erupts through volcano
17. a spot where sea-floor spreading occurs
20. when the cooler, more dense plate ____, this happens
21. the process of heat transferring from one object to another
22. a chain or group of islands that forms from volcanic activity along a subduction zone
24. the_____in the mantle is what causes plates to move

1. heat traveling through a liquid, naturally evaporating the less dense material, which causes condensation and humidity
2. the process of a continent moving
3. a supercontinent that existed millions of years ago
5. places where plates slide sideways past each other
7. the process of a ocean plate expanding, occurs at mid-ocean ridges
8. a large chunk of rock that makes up our land
12. Mass divided by Volume=?
13. Molten rock that flows out of the volcano
16. this forms when one ocean plate subducts under another
18. an area where the earth's crust is splitting apart
19. a area below a plate that generally a volcano is over, and is also pretty hot
23. a spot where the rock breaks because of an earthquake
