Choose a cookie. Don’t eat it… yet!
· First, carefully remove the top cookie (you must twist it!)
· Next, break the top cookie in half. As you do so, listen to the sound it makes.

Today we are going use an Oreo to learn about tectonic plates. The TOP cookie represents the tectonic plates (which are found on the top of the earth) and the icing/filling represents magma/lava (found under the plates).

Which of the following is true?

The cookie is the earth and the icing is water

The oreo cookie represents the Tectonic Plates and the icing/filling represents magma/lava

The icing/filling represents the Tectonic Plates and the cookie represents magma/lava

What natural disaster would cause a crack in the earth and would make a sound similar to that?

Hurricanes

Floods

Let’s look at divergent plate boundaries. Divergent boundaries are where the two plates MOVE AWAY from each other - like shown above.
What does divergent mean?

Moving together 

Sliding past each other

Moving apart 

Put one pointer finger on each broken half. Now push down (lightly) on the two broken cookie halves and pull them apart. What happens to the icing/filling?

Filling moves up in between the cookies

The edges of the cookie rub together and break apart

The cookies push together and rise up

When tectonic plates move away from each other at divergent boundaries, the magma is pushed up to the surface, hardens and creates new "ground" called sea floor. This is called sea floor spreading - beause the sea floor is literally "spreading out" and becoming larger

What landform is created at divergent boundaries?

New sea floor 

Volcanoes

Earthquakes

Mountains

When tectonic plates move away from each other at divergent boundaries, the magma is pushed up to the surface, hardens and creates new "ground" called sea floor. This is called sea floor spreading - beause the sea floor is literally "spreading out" and becoming larger

What causes the new sea floor at divergent boundaries?

The plates sliding on top of each other

The plates moving towards each other

The magma being pushed to the surface and cooling/hardening

Now let’s look at convergent plate boundaries. Convergent means that two tectonic plates move TOWARDS each other.

Moving together

Moving apart

Sliding past each other

Take the two cookie halves and slowly push them toward each other. Push one half of the broken cookie under the other half of broken cookie. What happens to the filling as the plates slide together?

The filling moves up in between the cookies

The filling changes color

The edges of the cookie rub together and break apart

What happens to the cookies as they push against each other?

The cookies push together and rise up

Filling moves up in between the cookies

The edges of the cookie rub together and break apart

What landforms do you think the cookies represent at this point?

New sea floor crust

Earthquakes

Mountains/volcanoes

What type of plate boundary created mountains and volcanoes?

Convergent (plates moving towards each other)     ->  <-

Divergent ( plates moving away from each other)   <-   ->

Seafloor spreading

Now let’s look at a transform plate boundary. Try sliding the two cookie pieces laterally past one another, over the creamy filling. What do you notice about the cookie edges?

The edges of the cookie rub together and break apart

The cookies push together and rise up

Filling moves up in between the cookies

You can feel and hear that the “plates” do not slide smoothly past one another, but rather stick and then let go. This phenomenon in the real world is described as

Mountains/volcanoes

New sea floor crust

Earthquakes

What type of plate boundary creates earthquakes?

Transform (plates moving opposite/past each other)  ^ v

Divergent ( plates moving away from each other)   <-   ->

Convergent (plates moving towards each other)     ->  <-

Match the name of the plate boundary

What causes tectonic plate movement?

Magma convection cells

They float on top of water

Solar radiation

Tectonic plates do not move

Describe what happens to the plates at a divergent plate boundary and draw the movement with ARROWS in the box.

Describe what happens to the plates at a convergent plate boundary and draw the movement with ARROWS in the box.

Describe what happens to the plates at a transform plate boundary and draw the movement with ARROWS in the box.

A zone of active volcanoes that encircles the Pacific Ocean

Hot death

Volcano islands

Ring of Fire

Ring of Volcanoes

Why do hotspots occur?

Magma is formed at a continental-continental convergent zone

Magma burns through oceanic plate and creates an island chain

Subduction zones cause magma to rise up when a plate is pushed into the mantle

At the boundaries between tectonic plates, sudden movements that are created when the plates slide past each other are called

Earthquakes

Mountains

Trenches

Volcanoes

What happens to magma at divergent boundaries?

Rises up to form new ocean floor

Ocean water falls into the center of the Earth

Tectonic plates never move

Earthquakes

What is the subduction zone?

The more dense continental plate moves under the other plate

The less dense oceanic plate moves over the other plate

The more dense oceanic plate moves under the other plate

Some of Earth’s landforms are created by hotspots where a plate rides over a fixed “plume” of hot mantle, creating a line of volcanoes. Imagine if a piece of hot, glowing coal were imbedded in the creamy filling – a chain of volcanoes would be burned into the overriding cookie. Name a location on Earth where this occurs.
