Earths System

1. Name of the ancient supercontinent when it was all one landmass
3. Sudden Events that led to a mass extension
9. Tectonic plates move toward each other, usually forms mountains and volcanoes
10. Formed as a result of high temperature and pressure deep within earth changing a rock that already exsisted
13. Deep, elongated dpressions in the ocean, often accosted with subduction zones
14. Forms after weathering and erosion when sediments compact and cement
15. Fractures or zones of weakness in Earth's crust
16. Large, rigid pieces of Earth's lithosphere that move and interact with each other along plate boundries
18. New oceanic crust is formed as tectonic plates pull apart magma rises
19. Instruments used to measure and record seismic waves
20. An opening at earths crust through which molten rock is pushed out and creates new rock

2. The semi fluid layer of the mantle where convection currents happen
4. Located between the mantle and outer core
5. A group of the same species living in the same area
6. Extinction events that occur over a longer period of time
7. Tectonic plates move away from each other, usually forms new crust and rift valleys
8. Includes the crust and upper part of the mantle and divided into tectonic plates
11. Rock formed when lava or magma cools or hardens
12. Formed at plate boundries usually where plates collide
16. Where tectonic plates slide past each other. Causes earthquakes
17. Hot material rises, cooler materials sink. It drives plate tectonics.
