Rock and Earth

3. The outermost and thinnest layer of the Earth. 5-25 miles thick
5. The first step in the process of creating sedimentary rock that is causes rocks to be worn down by the natural elements (ice, water wind)
8. melted rock is below the surface of the earth.
11. the process in which rocks change from one type to the other
12. The accumulation of sediment whether it is physical sediment (rocks and organic matter) or chemical sediment like salt.
14. is created through the process of
15. The process of moving the particles away from the original rock source
17. are located in the mantle and are responsible for the movement of the tectonic plates.
19. melted rock is above the surface of the earth.
20. is made of solid nickel and iron.
21. Erosion, Deposition, Compaction, Cementation

1. are responsible for the our magnetic north and south pole and for the magnetic field that protects us from the sun.
2. Is made up of the crust and the upper mantle. Also make up the tectonic plates
4. Is the middle part of the Mantle and because of the convection currents in its magma, it is responsible for the movement of the tectonic plates.
6. occurs when soil particles are pressed together
7. is created through the process of Melting and then Cooling
8. is created through the process of Heating and Pressure.
9. are produced naturally in earthquakes and can be used by scientists to determine the density and thickness of each layer of the earth
10. is the thickest layer of the earth. 2700 miles thick
13. is made of liquid nickel and iron. It is responsible for the electromagnetic field around the earth.
16. material that is broken down by processes of weathering and erosion
18. The last step in the creation of sedimentary rock that binds all sediment together to form rock
