• Atlantis

At which boundary do oceanic plates move across in a process called sea-floor spreading?

• Convergent

• Transform

• Divergent

• Subduction

At which plate boundary do tectonic plates move past each other causing earthquakes?

• Divergent

• Convergent

• Transform

• Subduction

Which is NOT a piece of evidence that supports continental drift?

At which boundary does an oceanic crust move below a continental crust forming a subduction zone and formation of volcanoes?

• Divergent Boundaries (Oceanic-Oceanic)

• Transform Boundaries

• Convergent Boundaries (Continental-Oceanic)

• Divergent Boundaries (Continental-Continental)

What is forming at B?

How does this image prove that all the continents were once together (aside from them fitting together like puzzle pieces)?

• The same fossils are found on continents that are now separate.

• The continents have similar climates.

• There are identical mountain ranges on different continents.

• The ocean currents are the same across all oceans.

What is forming at A?
