Sea Floor Spreading and Plate Tectonics

What is this a picture of?

• plate tectonics
• continental drift
• pangea
• glacier scaring

The Theory of Continental Drift states that Pangaea broke apart and the continents "drifted" away from each other

• True
• False

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary

A collision between two pieces of continental crust at a converging boundary produces a

• mid ocean ridge
• deep ocean trench
• rift valley
• mountain range

An underwater mountain chain caused by a divergent boundary, where new ocean floor is formed.

• mid ocean ridge

• volcano

• rift valley

• trench

A collision between a continental crust and an oceanic crust at a converging boundary produces a

• mid ocean ridge
• deep ocean trench
• rift valley
• mountain range

What are the two types of crust

• continental and oceanic
• ocean and upper
• lower and upper
• pizza and subway

Which layer has convection currents?

• Inner Core
• Outer Core
• Mantle
• Crust
