Limestone- sedimentary rock
Marble- metamorphic rock
![Page 19: Lecture9 rockcycle](https://reader034.fdocuments.us/reader034/viewer/2022052619/555733c2d8b42a320c8b5048/html5/thumbnails/19.jpg)
How is Turkey Like a Metamorphic Rock?
Transformed in the Solid State

If there is melting, then it’s not metamorphism

Earth’s
Internal structure
1. Core (2200 mi)
2. Mantle (1800 mi)
3. Crust (5-25 mi)
![Page 27: Lecture9 rockcycle](https://reader034.fdocuments.us/reader034/viewer/2022052619/555733c2d8b42a320c8b5048/html5/thumbnails/27.jpg)
Inner CoreMantle
Crust
Outercore
- solid (due to very high pressure)
- composed of Fe & Ni
- 7000-9000°F
![Page 28: Lecture9 rockcycle](https://reader034.fdocuments.us/reader034/viewer/2022052619/555733c2d8b42a320c8b5048/html5/thumbnails/28.jpg)
Outer Core
- molten
- composed of Fe & Ni
- 5400-7000°F
- generates magnetic field due to convective flow
Innercore
Mantle
Crust
![Page 29: Lecture9 rockcycle](https://reader034.fdocuments.us/reader034/viewer/2022052619/555733c2d8b42a320c8b5048/html5/thumbnails/29.jpg)
Mantle
Innercore
Crust
Outercore
- majority of Earth’s volume
- composed of oxides of Fe, Si, and Mg
- data from volcanic material & experimental work
- 3300- 5100°F
- divided into 3 zones
![Page 30: Lecture9 rockcycle](https://reader034.fdocuments.us/reader034/viewer/2022052619/555733c2d8b42a320c8b5048/html5/thumbnails/30.jpg)
3 mantle zones1. Uppermost mantle
- rigid
2. Asthenosphere- plastic
- moves indpt of lithosphere
3. Mesosphere- rigid

Crust- thin, brittle layer
- contains continents & ocean basins
- abundant elements: O, Si, Al, and Fe
Moho = discontinuity between crust & mantle
Lithosphere = crust +
uppermost mantle

Continental vs. oceanic
crust
Continental OceanicThickness thick thin
Composition granite basalt
Elements Si & Al Fe & Mg
Density low high

Isostasy• maintenance of
hydrostatic equilibrium of crust
-AKA buoyancy
• adding weight to crust = sink
• removing weight = rise
