Did Continents move away from each other?

Pangea, our first continent

Keywords: continental drift, Pangea, Alfred Wegner, Atlantic Ocean.
Continental drift states that the earth’s continents were joined as a single landmass that broke apart and was sent away from each other. The matching of landmasses on continents on opposite sides of the Atlantic Ocean states that one day these two continents were once joined together. Wegner supported the concept of drifting continents, were he observed that some of the rocks of the Appalachian Mountains in the United States shared similar features with rocks in Greenland and Europe. He also mentions similar fossils and ancient climatic data of the same type on continents that are today away from each other.
Questions:
  1. What is a continental drift ?
  2. What is pangea?
  3. What are the two different continents that we found simalar rocks on?
