Plate Tectonics Vocab Crossward

2. When Oceanic plates collide if there is a difference in density there is subduction which often creates trenches in the ocean floor.
5. A break in the earth’s crust.
9. When Plates collide and doing so shakes or reshapes the Earth.
10. When continental plates collide the crust gets folded and mountains form.
12. When one plate goes under another because there is a difference in density.
13. solid top most layer of the earth, includes crust and solid part of the mantle.
16. When plates move away from each other
17. A mountain spewing molten rock or lava from the Asthenosphere.
18. Volcanoes- When the Earth cracks far down and hits the asthenosphere creating a volcano inside a fissure in the Earth’s crust.
19. When Oceanic crust goes under continental crust and creates trenches in the sea floor.
20. Core- Solid inner most layer of earth, it is also made up of nickel and iron.

1. mantle- Solid uppermost part of the mantle.
3. Solid outermost layer of the earth subdivided continental crust and oceanic crust, broken into tectonic plates.
4. Gooey melted rock that is located directly under the lithosphere.
6. Events- Natural disasters caused by the movement of tectonic plates.
7. core- Really hot liquid metal and rock primary, metals are iron and nickel, It is also under the asthenosphere.
8. Boundaries- A place where two plates meet or collide.
11. When two plates collide with each other.
14. depression in the ocean floor usually by a subduction zone or fault line
15. currents- Heat transferred through the movement of fluids or gasses, based on density.
