 * continental drift**: Wegener's theory that the continents were once joined and slowly moved over Earth's surface.


 * fossil**:Any trace of an an ancient organism that has been preserved in rock.

Outline
=The Theory of Continental Drift=
 * Evidence from landforms- features on different continents match or line up
 * Evidence from fossils- similar fossils have been found on opposite sides of oceans
 * Evidence from climate- fossils show that climates were different in the past, possibly because the continent moved.

=**Scientists Reject Wegener's Theory**=
 * He could not provide a satisfactory explaination for the force that pushes or pulls the continents.
