Plate Tectonics Test

What is the thinnest layer of the earth’s composition?

• mantle
• inner core
• crust
• outer core

What evidence did Wegener use in his theory?

• Continents and fossils fitting together/matching-up like puzzle pieces 
• glacier scars and other climate evidence from temperature
• mountain ranges and rocks line up across continents
• all of the above

Convection occurs in the _________________ and causes the plates to move.

• crust

• core

• mantle

• molten

The theory that pieces of the Earth's lithosphere are in constant motion, driven by convection currents in the mantle is called:

• Radiation
• Plate Tectonics
• Pangea
• Continental Divide

The San Andreas Fault in California is an example of a ________.

• the continents are all moving together and will soon collide

• the continents are floating around on a large ocean

• Earth is expanding

Continental drift is the idea that

• continents move over time

• some continents subduct under others

• Earth's magnetic pole has reversed

• earthquakes occur at plate boundaries
