Earth Systems

5. where tectonic plates slide past each other, causing earthquakes
7. Deep, elongated depressions in the ocean, often associated with subduction zones
8. Large, rigid pieces of the earth's lithosphere that move and interact with each other along plate boundaries
9. formed at plate boundaries when plates collide
11. new oceanic crust is formed as when it was all one land mass plates pull apart and magma rises
16. Hot material rises cool material falls It drives plate tectonics
18. Extinction events that occur over a long period of time
19. Includes the crust and the upper part of the mantle, and is divided into tectonic plates
21. Formed after weathering and erosion when sediments compacts and cement

1. An opening to the Earth's crust which through molten rock is pushed out and creates new rock
2. Tectonic plates move towards each other, usually forms mountains and volcanoes
3. tectonic plates move away from each other, usually forms new crust and rift valleys
4. Sudden events that lead to mass extinction
6. Fractures or zones of weakness in the earths crust
10. Instruments used to measure and record seismic waves
12. A group of the same species living in the same place
13. Name of the ancient supercontinent
14. located between the mantle and the outer core
15. The semi-fluid layer of the mantle where convection currents happen
17. Formed as a result of high temperature and pressure deep within the earth changing a rock that already existed
20. Rock form when lava or magma cools and hardens
