Forming our Earth
The 3 parts of the earth 1.The crust is less than 25 mi thick and is rocky 2.The mantle is a liquid plastic-like layer 3.Outer core liquid Fe-Iron, and S-Sulfur 4.Inner Core Solid Fe-Iron Draw this model and label Crust,Mantle, Inner Core, and Outer Core
Earth’s moving plates Plate tectonics- A theory stating that the crust of the Earth is composed of plates moving on the molten mantle below. Continental Drift- Movement of the continents over the Earth's surface.
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 Convection Go back and look at your drawing of the parts of the Earth
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 1.Lithosphere= icing 2.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!!!
