Plate tectonics, or plate movements, have changed the way geologists think about the Earth. The area where two plates meet is called plate boundaries.
Antarctica was most likely near the equator millions of years ago. This also explains the evidence of glaciers in the Sahara Desert. Science Inquiry—You will conduct online research in which you will collect information, make observations, and Plate tectonics essay rubric your results in written form.
When the continents and oceans move about the surface, it is similar to passengers on a raft. Sand and gravel in long rows showed that the middle of the Sahara Desert was once covered in a glacier.
Plate tectonics is a combination of two ideas, sea-floor spreading and continental drift. This section contains words approx. When you have finished, submit your work to your teacher. Rubric This rubric will be used by your teacher to grade your assignment.
Now, write a to word essay about the processes involved in plate tectonics. One plate is destroyed when continental and oceanic plates collide. Overtime, scientists realized that fossils were found in places where they should not be.
Directions Write a response for each of the following activities. Be sure to include examples and evidence supporting the concept of plate tectonics. Sea-floor spreading is also the movement of crust away from the mid-ocean ridges.
Inspreading plate margins became part of the theory of plate tectonics. Both volcanic and seismic activty when plotted on a map can be seen to follow certain patterns and it is this distribution that helps explain the plate theory.
He then said that Pangaea had drifted apart through the movement of plates to give us the current places of continents we have today.
That made them begin to wonder. This theory explains not only about how ancient crust is destroyed along destructive plate margins, but it also explains how new ocean floor is created.
In the rocks at the top of the Himalaya Mountains, scientists found many fossils. Whereas seismicity is where the build up of pressure in the crust is released. Type your response here: The distributions of earthquake events are found in broad, uneven belts around plate margins and it is the movement of the plates that cause the seismic events.
This means that although volcanic and seismic events help to prove the plate tectonics theory valid, there is also a range of other factors involved. Details major plates and how the theory helps predicts earthquakes. Describes the theory of plate tectonics and how the theory has changed the way geologists think about the Earth.
The plate tectonics theory was put forward by Alfred Wegener suggesting that the continents were at one point all conjoined in one supercontinent known as Pangaea.

Convection currents will "carry" the oceanic plate back to the mantle, after going under the continental plate. Those people thought that it was exactly like it has always been. There are nine major plates. In Antarctica, fossils of trees, ferns, and plant-eating dinosaurs were found.Plate Tectonics Essay Words | 3 Pages.
A plate tectonic is defined as a solid rock mass that builds up the Earth’s surface. The plate tectonic theory is a theory that geologists use to help explain the surface processes and events. Plate tectonics is the unifying theory of geology, said Nicholas van der Elst, a seismologist at Columbia University's Lamont-Doherty Earth Observatory in Palisades, New York.
