plate

lithosphere

tectonic

pangeae

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

proves Pangaea existed

means the mountains were always separate

What would happen if convection currents in the mantle stopped?

increase the number of earthquakes

create more volcanoes

tectonic plates would stop moving

create new crust

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?

the plates are diverging
