Answer to the bellringer is:

• A

• B

• C

• D

Layers of the Earth

As depth increases, pressure increases. 

As depth increases, temperature increases. 

As depth increase, density increases.  

Multiple Choice

Which layer has the highest pressure, temperature and density?

• Crust

• Mantle

• Inner Core

• Outer Core

Plate Tectonics

when the lithosphere (part of the crust) slowly moves, carrying pieces of continental and oceanic crust.

Why do plates move?

Convection Currents

Occurs in the Mantle.

Hot liquid/gas travels upward putting pressure on the crust which causes the plates to move.

Multiple Choice

Why does the hot liquid rise and the cold liquid sink in the mantle?

• hot liquids are less dense than cold liquids.

• hot liquids are more dense than cold liquids.

• hot liquids have no density.

• hot liquids move quickly and have a higher density than cold liquids.

Subduction Zone

During convergent boundaries, the oceanic crust is DENSER than the continental crust. Therefore, it will sink or subduct.

Multiple Choice

GOLDEN TICKET: Earth crust is made up of tectonic plates. This diagram shows two plates found under the Himalaya mountains. Which of the following statements best describes the tectonic plates shown in the diagram?

• Two continental crust converging

• Continental and oceanic crust converging

• Two continental crust dividing

• One oceanic crust and continental crust sliding

Multiple Choice

The following represents a rift valley. What occurred during a rift valley?

• Two continental plates dividing

• Two oceanic plates seperating

• Seafloor Spreading

• Plates came together

Open Ended

What type of plate boundary causes a volcano?

Multiple Choice

What plate boundary causes frequent earthquakes?

• divergent

• transform

• convergent

• seafloor spreading

Activities Directions:

• When your teacher says begin, you will grab the cards and the headphones from underneath your desk.

• At this time, you are working with a partner with voice level 1. (teacher needs to hear the sounds)

• If you get stuck, read your GREEN checklist.

• Do not move on to another activity until your teacher tells you to do so.

• You will have 6 minutes per activity.

• You may go back to past activities if you did not finish.

• do not submit we will go over the answers at the end.

Activity 1?

• What force moves the tectonic plate? Convection Currents in the mantle

• How do convergent boundaries move? towards each other

• How divergent boundaries move? Away, seperate

• What happens in convergent boundary during subduction zones? the oceanic crust sinks down because it is more dense

Activity 2

What boundary occurred at A? Transform, plates sliding.

What would happen at A? Earthquakes

What boundary occurred at B? Divergent, plates dividing.

What would happen at B?

Seafloor Spreading

What boundary occurred at C? Convergent, plate colliding.

What would happen at C?

Mountains

Activity 3

which model represents a plate boundary that result in earthquakes? C

What model represents divergent boundary? B

At a divergent boundary, which landform would you expect to find: volcano or mid ocean ridge? Mid ocean ridge
