Bellwork 11-13-13
Obj: SWBAT describe the layers within the earth.
1.What happens to the temperature as you move from the crust to the core of the earth?
2.What happens to pressure as you move from the crust to the core of the earth.
3.Which layer of the earth is liquid?4.What layer do you think is the most density, or the
heaviest?
Earth Structure- The thickness of the layer-The name of the layer- Temperature- Composition- If it is solid or liquid-
Notetaker setupOn each box include:
Putting temperature into perspective
-Boiling hot water= 212°F or 100°C
-Stove (gas\electric)=1800°F
-Red hot iron= 1,000 °C (1,830 °F)
-Copper= 1084 °C (1983 °F)
-Blowtorch flame= 1,300 °C (2,370 °F)
-Glass=1500 °C (2000 °F)-Iron= 1538 °C (2800 °F)-Diamond= 3,550 °C (6422°F)-Tungsten= 3410 °C (6170 °F)-Surface of the sun= 6000 °C (10,832°F)-Core of the sun= 15,000,000°C
Starting from the outside in... The Earth’s
Crust makes up only ONE percent of its total mass!
Ocean Crust= 5-6 km(3.1-3.7 miles) thick
Continetial Crust=15 -75km thick(9-46 miles)
Ocean Crust= 5-6 km(3.1-3.7 miles) thick
Ocean Crust is mostly made of Basalt
Basalt has an average density
of 3.3 g/cm3
Continetial Crust
15 -75km thick(9-46 miles)
Continetial Crust
is mostly made out of Granite
Average density= 2.7 g/cm3
Crusty Chemistry
The crust is mostly made up of rocks that contain magnesium potassium, iron, sodium, aluminum, silicon, and oxygen.
The Top Four!
Oxygen O 46.60% 100,000,000 tons
Silicon Si 27.72% 3,880,000 tons 5000 tons electronic grade
Aluminum Al 8.13% 30,000,000 tons
Iron Fe 5.00% 1,200,000,000 tons
Upper mantle chemistry
-The upper mantle contains magnesium, iron, aluminum, silicon, and oxygen.
*notice the ”lighter” elements disappear and are left in the crust
Na, K, Ca
The MantleThe Mantle makes up two-thirds of Earth’s
mass and is 2,900km thick (1800miles)!
*Average temperature of the mantle = 1000-2200 C (1832-3992 F)
Outer core-The outer core is 2250 km thick and has an average temperature of 3700°C (6700°F)
-Also responsible for the Earths magnetic field
-Composed of liquid Iron, Nickel, oxygen, and sulfur
