Continental Drift and Plate Tectonic Theory

What is the Theory of Continental Drift?

• New continents are continually being created

  and destroyed.

• The layout of the continents is the same today

  as it has always been

• The continents have always been separate but

  may one day drift together to form a single

  continent

• All the continents were once one continent that

  broke up and drifted apart over hundreds of

  millions of years
