Question
Fossil corals about 370 million years old have been discovered
along much of the length of the Appalachian mountain system
in the United States-as shown by the red stars on the map to
the right. Today corals are generally found in tropical and sub-
tropical climate zones, between 30°N and 30° S latitudes, and
rarely as far north as the northern part of the Appalachians.
(a) What does the presence of these coral fossils suggest
about the location of North America 370 million years ago?
(b) The east coast of the United States today is oriented nearly
straight north-south.
• Do you think the orientation of the east coast was the same 370 million years ago? Why or why not?
• When they were alive, were the corals closer to or farther from the equator than the fossils are today?
