Tectonic Plates

What is Pangaea?

• The name of a German Scientist
• the name of the supercontinent that existed millions of years ago
• another name for continental drift
• the name of an ancient fossil

What are mid-ocean ridges?

• A chain of underwater waterfalls 
• A chain of underwater volcanos
• A chain of underwater mountains
• A chain of underwater rocks

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

Who is the person credited with developing the theory of continental drift?

• Harry Hess
• Galileo
• Alfred Wegener
• Newton

The source for convection currents in the mantle comes from these layers...

• inner core and crust
• outer core and crust
• mantle and crust
• outer core and mantle

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

• True
• False

Which piece of evidence did Wegener use to prove continental drift?

• The shape of the continents
• Similar fossils found on separate continents
• Tree fossils found in odd places
• All of the above

Why did no one believe Wegener's thoery?

• He could not explain HOW the continents moved
• He didn't have evidence
• His data was wrong
• He didn't use the right technology to gather data

The movement of Earth's crust along plate boundaries produces

• earthquakes
• volcanoes
• mountains
• All of these options. 

This layer of Earth is solid Iron and Nickel

• Outer Core
• Mantle
• Inner Core
• Crust
