Forming our Earth. The 3 parts of the earth. The crust is less than 25 mi thick and is rocky The mantle is a liquid plastic-like layer Outer core liquid Fe-Iron, and S-Sulfur Inner Core Solid Fe-Iron. Draw this model and label Crust,Mantle , Inner Core, and Outer Core. Earth’s plates.

Earth’s moving plates Plate tectonics- Continental Drift- Movement of the continents over the Earth's surface. • A theory stating that the crust of the Earth is composed of plates moving on the molten mantle below.
Continental Drift: Check it out! • Click on earth • Why do they not fit perfectly back together?
The Untold Tragedies of Continental Drift • Using continental drift to predict the future! • Click cartoon!
If Wegener only knew… This is the current theory of how the continental plates drift Go back and look at your drawing of the parts of the Earth Convection
Convection- The transfer of heat by a moving fluid. • Convection currents in the mantle moves the Lithosphere
Two types of movement Lithosphere- the upper mantle and the crust of the earth together.
Asthenosphere- The middle of the mantle containing convection currents
Words to Know for tomorrow(Warning: below words have swag!) • Continental Drift • Tectonic Plates • Convection Currents • Lithosphere • Asthenosphere
Draw it • On the left side….draw AND label the lithosphere and asthenosphere on something else that has layers. It does not have to make sense. • Example • Lithosphere= icing • Asthenoshpere= cupcake Does 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!!!
