Internal processes continually build up the surface of the earth, while __________________ processes break it down.
Atmospheric
Hydrogeological
External
Volcanic
Earth's internal processes are driven primarily by what?
Heat and convection currents
Ocean currents
Weathering and erosion
Earthquakes and volcanoes
Why was the theory of plate tectonics initially rejected?
It didn't explain how continents move
It did not explain formation of islands
It was based upon false statements
There was no data to support the hypothesis
Which of the following is NOT evidence of continental drift?
Continents fit together like puzzle pieces
Volcanic activity
Fossil evidence
Mineral, rock, and glacial deposit evidence
Present day fossils of similar organisms are found on different continents. This supports the theory of continental drift how?
The environment of these organisms was once connected when continents were joined
The organisms were avian and could live in a wide range
The organisms often migrated
The organisms had a large population that was widespread
Which of the following is evidence that mountain ranges on different continents were once connected?
They have the same climate
They are inhabited by similar wildlife
They are the same age
They have no trees beyond a certain height
At what rate do continents continue to move?
About 7 feet a year
About 2 centimeters per year
They are not moving
About 15 feet per year
Why don't present day continents fit perfectly together?
Weathering and erosion of coastlines
They have been twisted by earthquakes
Fossils
Human actions have changed the shape of coastlines
