True or False: Continental Drift is an appropriate name for the phenomenon that Wegener was trying to explain.

Back

True

Front

Which feature is the oldest in a sequence of rock layers?

Back

The oldest feature is typically the one at the bottom of the sequence.

Front

What is the Law of Superposition?

Back

A principle stating that in undisturbed rock layers, younger rocks lie above older rocks.

Front

What evidence supports the theory of Continental Drift?

Back

Fossils of Mesosaurus found on multiple continents suggest they were once connected.

Front

Why did most geologists reject Wegener's idea of Continental Drift?

Back

He didn't have a good explanation of what would cause continents to move.

Front

What is relative dating in geology?

Back

A method of determining the age of rocks by comparing them to other rocks.

Front

What is the significance of Mesosaurus fossils in the study of Continental Drift?

Back

They indicate that continents were once connected, as Mesosaurus could not swim across oceans.

Front

What does the term 'unconformity' refer to in geology?

Back

A gap in the geological record where rock layers have been eroded or not deposited.

Front

What is the role of fossil evidence in supporting geological theories?

Back

Fossils provide clues about past environments and the movement of continents.
