CRUST
1. 2 TYPES-CONTINENTAL AND OCEANIC
2. CONTINENTAL COMPOSITION- GRANITE ROCK,
LESS DENSE THAN OCEANIC, THICKER, OXYGEN,
SILICON AND ALUMINUM
3. OCEANIC COMPOSITION- BASALT ROCK,
THINNER AND MORE DENSE THAN CONTINENTAL
CRUST-HAS MORE IRON, CALCIUM AND
MAGNESIUM
4. TEMPERATURE OF CRUST- 0-1,000 DEGREES C
5. DENSITY OF CRUST- 2.2-2.9 G/CM3
OCEANIC- 2.9
CONTINENTAL 2.2
6. THICKNESS- 5-100 KM
CONTINENTAL- 30-100 KM
OCEANIC- 5KM
MANTLE-3 PARTS
L-LITHOSPHERE
A-ASTHENOSPHERE
M-MESOSPHERE
1. COMPOSITION OF LITHOSPHERE- TECTONIC
PLATES, PART OF CRUST AND MANTLE, SOLID/RIGID
2. COMPOSITION OF ASTHENOSPHERE- SOLID
ROCK FLOWING SLOWLY, STRETCHES, CONVECTION
CURRENTS MOVE TECTONIC PLATES
HERE/TECTONIC PLATES FLOAT ON TOP OF THIS
LAYER
3. COMPOSITION OF MESOSPHERE- STRONG,
LOWER PART OF MANTLE
***MANTLE COMPOSITION HAS MORE
MAGNESIUM AND LESS ALUMINUM AND SILICON
THAN CRUST-SEMI-SOLID ROCK AND MOLTEN
ROCK***
4. TEMPERATURE OF MANTLE- 1,000-3,700
DEGREES C
