Mar 21, 2013 · In 1977, after decades of tediously collecting and mapping ocean sonar data, scientists began to see a fairly accurate picture of the seafloor emerge. The Tharp-Heezen map illustrated the geological features that characterize the seafloor and became a crucial factor in the acceptance of the theories of plate tectonics and continental drift. Today, these theories …

Theory of Plate Tectonics. When the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth’s surface. Like the scientists before us, we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics.

3. Compare the map of the world today (such as the real-time earthquake map) to a map of the world 250 million years ago (called Pangaea). Use the interactive continental drift map to watch the change in the Earth’s landforms over millions of years. As you watch the animation, record at least three examples of how the continents have changed

Plate Tectonics. Plate tectonics is the study of the lithosphere, the outer portion of the Earth consisting of the crust and part of the upper mantle. The lithosphere is divided into about a dozen large plates which move and interact with one another to create earthquakes, mountain ranges, volcanic activity, ocean trenches and many other features.

Plate tectonics describes the motions of the 15 to 20 large rigid and brittle tectonic plates into which the Earth's outermost layer (called the "lithosphere") is broken. ...
