Plate Tectonics

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

Originally the Continental drift theory was not well received by other scientists. Why?

• There was a competing theory at the time that was more believable.

• There was no data showing the continents ever moved.

• Wegener could not explain the mechanism that made continents move

• The scientist presenting the data was unreliable.
