2 The 3 parts of the earthThe crust is less than 25 mi thick and is rockyThe mantle is a liquid plastic-like layerOuter core liquid Fe-Iron, and S-SulfurInner Core Solid Fe-IronDraw this model and label Crust,Mantle,Inner Core, and Outer Core
4 Earth’s moving platesPlate tectonics-Continental Drift-A theory stating that the crust of the Earth is composed of plates moving on the molten mantle below.Movement of the continents over the Earth's surface.
5 Continental Drift: Check it out! Click on earthWhy do they not fit perfectly back together?
6 The Untold Tragedies of Continental Drift Using continental drift to predict the future!Click cartoon!
7 If Wegener only knew…Go back and look at your drawing of the parts of the EarthConvectionThis is the current theory of how the continental plates drift
8 Convection- The transfer of heat by a moving fluid. Convection currents in the mantle moves the Lithosphere
9 Two types of movementLithosphere- the upper mantle and the crust of the earth together.
10 Asthenosphere- The middle of the mantle containing convection currents
11 Words to Know for tomorrow (Warning: below words have swag!) Continental DriftTectonic PlatesConvection CurrentsLithosphereAsthenosphere
12 Draw itOn the left side….draw AND label the lithosphere and asthenosphere on something else that has layers. It does not have to make sense.ExampleLithosphere= icingAsthenoshpere= cupcakeDoes not have to be food, but something original!Then write a sentence, if this was like the earth then what would the asthenosphere make move……….SPRINKLES!!!
