The ocean basins, on the other hand, are all less than 150 million years old.
What has changed, is the shape and the distribution of continents across the globe.
The second goal is to illustrate the changing distribution of mountains, lowlands, shallow seas, and deep ocean basins through time.
The past positions of the continents can be determined using the following five lines of evidence: paleomagnetism, linear magnetic anomalies, paleobiogeography, paleoclimatology, and geologic history.
The Earth's climate is primarily a result of the redistribution of the Sun's energy across the surface of the globe.
It is warm near the Equator and cool near the Poles.The similarity or dissimilarity of faunas and floras on different continents can be used to estimate their geographic proximity.
