Take Plate Tectonics Notes

Answer Reflection Questions

Reminder for Notes

• You *may* copy the notes live if you want

• But, you do not have to

• This slides are available in canvas

• You can copy the notes whenever it is the most convenient for you to do so

Multiple Select

What is the evidence for the theory of plate tectonics?(check all that apply)

• locations of earthquakes

• measuring movement of earth's surface

• shape of the continents

• magnetic minerals

• fossil record

Multiple Choice

How does a convection current work?

• material moves due to gravity

• material moves due to electric currents

• material moves due to magnetic fields

• material moves due to uneven heating

Multiple Choice

How are continental plates and ocean plates different?

• ocean plates are cold and sink; continental plates are hot and float

• ocean plates are thick and strong; continental plates are thin and brittle

• continental plates are cold and sink; ocean plates are hot and float

• continental plates are thick and strong; ocean plates are thin and brittle

Multiple Choice

Why is a convergent plate boundary called a destructive boundary?

• old crustal material is pushed down and melted at this plate boundary

• old crustal material is dissolved by the ocean at this plate boundary

• new crustal material replaces older rocks at this boundary

Multiple Choice

Why is a divergent plate boundary called a constructive boundary?

• new continental crust absorbs old continental crust at this boundary

• old continental crust sinks and is covered by new crust at this boundary

• old continental crust breaks open and is filled with new crust at this boundary
