Forming our earth

Forming our Earth

The 3 parts of the 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 plates

Earth s moving 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

Continental Drift: Check it out!

  • Click on earth

  • Why do they not fit perfectly back together?

The untold tragedies of continental drift

The Untold Tragedies of Continental Drift

  • Using continental drift to predict the future!

  • Click cartoon!

If wegener only knew

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


Forming our earth

  • Convection- The transfer of heat by a moving fluid.

  • Convection currents in the mantle moves the Lithosphere

Two types of movement

Two types of movement

Lithosphere- the upper mantle and the crust of the earth together.

Forming our earth

Asthenosphere- The middle of the mantle containing convection currents

Words to know for tomorrow warning below words have swag

Words to Know for tomorrow(Warning: below words have swag!)

  • Continental Drift

  • Tectonic Plates

  • Convection Currents

  • Lithosphere

  • Asthenosphere

Draw it

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!!!
