Continental Drift vs. Plate Tectonics
(Similarities and differences)
Continental Drift
-
Describes continents
-
Continents rearrange
( join together and
drift apart)
-
Original idea
-
Proposed by Alfred
Wegner in 1915

Describes the earth’s
plates (including crust

-
Lithosphere is destroyed
and formed at plate
boundaries
-
Modern theory
supported by additional
evidence such as
satellite measurements
of continental movement.

Helps explain earthquak

Test on Thursday (10.18.2012)
• Ms. Kim is not available on Wednesday
10.17.2012 (Wednesday, the day before
the test).
• If you have questions, ask me before
Wednesday.
• Study ahead of time.
• We will review on Monday (Content
covered – everything since day 1)
