Nine Week Science

The Appalachian Mountains stretch from Mississippi up to Newfoundland, Canada. What is the best explanation for how this mountain range formed?

• Wind has pushed rocks and soil into valleys that have built up over time

• Volcanoes erupted for long periods of time and slowly built up the mountains.

• Rivers and streams flowing down from Canada deposited soil in large amounts until the mountains formed

• Parts of Earth's crust slowly collided until one part was on top of the other and pushed upward.
