The new volcano that is currently forming off the coast of Hawaii is known as _______.

Which type of plate boundary results from two or more plates coming together?

According to Wegener's work,Glossopteris thrived in a warm environment.

In the diagram below,which two are the best examples of the "puzzle-piece" argument?

According to the figure below,the Caledonides in Scotland and Scandinavia are also part of the _______ in North America.

The point on the surface directly above an earthquake occurrence is called the _______.

Paleomagnetic data provide evidence for the geographic position of continents in the past.

In the figure below,how many magnetic reversals occurred between 2.0 and 1.5 million years ago?

How did the presence of Glossopteris fossils support Wegener's idea of continental drift?

A hypothesis develops into a theory if it is repeatedly proven through further testing.
