ES UA #2 Plate Tectonics 22-23

What is tectonic plate theory?

• The idea that the earth is broken into pieces that move.
• The theory that the continents were once connected.
• Continents are drifting.
• I heart eating dinner on plates. 

What is continental drift theory?

• Continents are sinking into the ocean.
• Continents were once connected and have drifted apart.
• The lithosphere is broken into large pieces that move.
• The ocean waves move the continents around. 

What scientist proposed continental drift theory?

• Harry Hess
• Albert Einstein
• Alfred Wegener
• Mike and Sully

Which of the following is evidence for plate tectonic theory?

• Fossils match up across continents.
• GPS can measure continents moving each year.
• Glacier grooves match up on different continents.
• All of these

What causes the tectonic plates to move?

• Convection currents in the mantle.
• Convection currents in the crust.
• Conduction currents in all layers of the earth.
• The wind and the ocean waves. 

What is the importance of the location of these earthquakes on this map?

• They are randomly located.
• Some areas will never get an earthquake. 
• They are mostly located at plate boundaries.
• They are very predictable.
