2 Understanding Earths Interior This Activity will allow you to become familiar with the Earths layers and the process that occur within them.

3 Click on the star to Begin Core Follow-Up Exercise

4 Crust Solid Solid Composition: Oxygen, aluminum, Calcium, Iron, sodium, potassium, magnesium, Silicon Composition: Oxygen, aluminum, Calcium, Iron, sodium, potassium, magnesium, Silicon 5-40 km thick but has an average of 32 km 5-40 km thick but has an average of 32 km

5 Earths Crust s/Earths_crust.gif Earths crust is composed of a dozen plates covering earths surface. These dozen are either oceanic or continental crust.

6 Click on the star to continue….. Core

7 Mantle 2800 km thick 2800 km thick Is both solid and liquid Is both solid and liquid Composition: Silicon, Oxygen, Iron, Magnesium Composition: Silicon, Oxygen, Iron, Magnesium There are convection cells in the mantle that cause important forces on the surface. There are convection cells in the mantle that cause important forces on the surface. Next: What are convection Cells?

9 Click on the star to continue…… Core

10 Core Inner Core Composition- Iron and Nickel Composition- Iron and Nickel 1,200 km thick 1,200 km thick degrees Celsius degrees Celsius Solid, because of enormous pressure of overlying matter Solid, because of enormous pressure of overlying matter The core is divided into two layer: the Inner and Outer core Outer Core Composition - Nickel and Iron 870 degree Celsius 2,250 km thick Liquid layer

11 Earth’s Magnetic Field Earth’s rotation causing the liquid iron outer core to spin around the solid iron inner core is believed to cause the formation of Earth’s Magnetic Field.

12 Quick Quiz Earths crust is divided into two types. They are? A.Surface and continentalSurface and continental B.Continental and OceanicContinental and Oceanic C.Oceanic and MantleOceanic and Mantle D.Mantle and SurfaceMantle and Surface

13 Quick Quiz Earth’s inner core is hotter and solid, while the outer core is colder and liquid? Why is this? A.The inner core is made out of material that resists heat better. The inner core is made out of material that resists heat better.The inner core is made out of material that resists heat better. B.The Outer core is not even solid, but is liquid also. The Outer core is not even solid, but is liquid also.The Outer core is not even solid, but is liquid also. C.The inner cores overlying pressure causes it stay solid. The inner cores overlying pressure causes it stay solid.The inner cores overlying pressure causes it stay solid.

14 Quick Quiz Temperature increases with pressure, then this layer has the lowest pressure? A.Core Core B.Crust Crust C.Mantle Mantle

15 Quick Quiz This is formed by movement of mantle material? A.Magnetic Field Magnetic FieldMagnetic Field B.Convection Cells Convection CellsConvection Cells C.Earths rotation Earths rotationEarths rotation

17 That is Correct

18 That is Super

19 That is Awesome

20 You Nerd You

21 AHHHH Try Again!!!!!!
