How Noth America go its shape

Continents, countries, and even mountain ranges didn't always look the way they look now. Millions of years ago, every continent had a different shape. The force that changes continents and mountains is called tectonics, and each continent sits on a tectonic plate.

Read pages 28 and 29 in the textbook, and answer the questions.
Also think about why tectonic plates, volcanoes, and earthquakes are connected. link

After watching the video, answer:
  • What happens when one plate goes underneath another? 
  • What did the continents look like  millions of years ago? 
  • What does "rift" mean? 
  • Name the different tectonic plates in this region
