1 point

The Andes Mountains are a result of the Nazca Plate (oceanic) and South American Plate (continental) interacting. What are these two plates doing to create a mountain range?

South American plate subducts under the Nazca plate

the plates create a transform boundary

Nazca plate subducts under the continental plate

the plates are diverging

12.

1 point

If new crust is being produced at the mid-Atlantic Ridge, what happens to older crust?

makes Earth larger

sinks into mantle at subduction zones

melts at transform boundaries

sinks into mantle at seafloor spreading

13.

1 point

Wegener discovered that the Appalachian Mountains are the same as the Scottish Highland mountains thousands of miles away on a different continent. How did this evidence support his theory?

proves Pangaea never existed

means the mountains were always separate
