• Mountains

• Mid-Ocean Ridges

• Rift Valley

• Dormant Volcano

At what type of plate boundary do mid-ocean ridges form? What process happens?

• Convergent and seafloor spreading

• Divergent and seafloor spreading

• Convergent and subduction

• Divergent and subduction

What supports Continental Drift and Plate Tectonic Theory?

• Earth's crust is made of plates that are slowly moving over, against, and apart

• Fossils, rock and mountains ranges are evidence that support these

• All the continents once formed a supercontinent

• All the statements support the theories

Did most scientists believe Wegener's Theory of Continental Drift? Why or Why Not?

• Yes, there was much evidence to prove how the continents moved.

• No, there was a lack of technology to prove how continents moved.

• Yes, technology was great back then, so it was very clear it was true.

• No, Wegener had zero evidence and it was just an idea he imagined.

With new technology, what did scientists discover that supported Continental Drift Theory?

• That the seafloor is actually spreading and creating new oceanic crust which forces old crust in opposite directions.

• Scientists climbed volcanoes and measured how tall they were and the magma.

• Scientists traveled to the center of the earth and saw convection currents.

• Scientists measured earthquakes to understand

What is the correct order of Pangaea breaking up.

• 1. 1. 7 separate continents 2. slowly started to moving together 3. connected as 1 supercontinent

• 1. 1. continents connected as 1 supercontinent 2. slowly started to separate 3. 7 separate continents

• 1. 1. some continents together 2. slowly all connected into Pangaea 3. separated into 7 continents

• 1. 1. only South America and African connected 2. slowly started to separate 3. 7 separate continents

What are most volcanoes and earthquakes caused by?

• Hotspots (not associated with plate boundaries)

• Tectonic plate boundaries (plates interacting with each other)

• Volcanoes and earthquakes are caused by totally different natural events

• None of the above

At some plate boundaries, magma comes to the surface to make new crust/rock. What causes this movement of magma?

• Conduction Currents in the Mantle

• Convection Currents in the Mantle

• Conduction Currents in the Crust

• Convection Currents in the Crust

What is the name of the fossil that was found on 5 continents and provided evidence to Pangaea?

• Tyrannosaurus Rex (a dino)

• Trilobite (a marine arthropod)

• Glossopteris (a fern)

• Ptychodus (a shark)
