What is the continental drift theory?

• The layout of the continents is the same today

  as it has always been.

• All the continents were once one continent that

  broke up and drifted apart over hundreds of

  millions of years

• new continents are continually being created

  and destroyed.

• The continents have always been separate but

  may one day drift together to form a single

  continent.
