Plate
tectonic theory, which developed from the hypothesis that continents on
opposite sides of the Atlantic Ocean had drifted apart, is one of the most
revolutionary concepts developed in all of science during the last century.
As with any great theory, it has developed geologists understand considerably
more than its original intent, which was to explain the obvious puzzle-like
fit between continents on opposite sides of the Atlantic Ocean. Development
of the theory has progressed to the extent that it allows geologists to
better understand earthquakes, volcanic activity, the origin of rocks and
mineral deposits, mountain building, the distribution of fossil remains,
the origin of features on the ocean floor, and much more.
There
are only few aspects of the broad spectrum of geological phenomena that
are not linked or explained in some way by this theory. |
