1. core-interior of the earth.
2. mantle- surrounding the molten outer core is a hot pliable layer of rock.
3. cruts- outter layer of the earth is a cool, light weight, brittle rock that floats on the mantle.
4. tectonic plates- upper layer mantle as a huge convection currents that break the over laying cruts into mosaic huge blocks.
5. mineral- naturally occuring, inorganic soild element or compound with a definate chem comp and reg internal crystal structure.
6.rock- soild cohesive aggreate of one or more minerals.
7. igneous rock- most common rock-type ine the earth’s cruts is solidfied from magma welling up from the earth’s interior.
8.wethering- exposure to air, water changing temperature amd reactive chemicals slowly breaks down
9. sedimentation- particles of rock are transported by wind water ice and gravity until they come to rest again in a new location.
10.sedmentary rock- deposited material that remians in place long enough or is coered with enough material to compact it may once again become rock
11. metamorphic rock- preexisting rocks can be modified by heat pressure and chemial agents to create new forms.
12.smelting- roasting ore to relase metals.
13. heap-leach extraction- invloves piling curshed ore in huge heaps and spraying it with a dilute alcakine soultion.
14. earthquakes- sudden movements in earth’s crust that occur along faults.
15. tsunami- giant sea wells that move away from the center of an earthquake.
16.volcanoes- undersea magma vents produce much of the earths curts
17. mass wasting- geological materials are moved downslope from one place to another.
18. magma- molten rock.
19.rock cycle- ceration destruction and metamorphsis
