Plate Tectonics

Front

Earth's internal processes are driven primarily by what?

Back

Heat and convection currents

Front

Who first developed the Theory of Plate Tectonics?

Back

Alfred Wegener

Front

Why was the theory of plate tectonics initially rejected?

Back

It didn't explain how continents move

Front

Which of the following is NOT evidence of continental drift? Continents fit together like puzzle pieces, Fossil evidence, Mineral, rock, and glacial deposit evidence

Back

Ring of Fire

Front

Present day fossils of similar organisms are found on different continents. This supports the theory of continental drift how?

Back

The environment of these organisms was once connected when continents were joined

Front

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

Back

They are the same age

Front

Some fossils found on Antarctica required a tropical climate to live. How does this support the theory of continental drift?

Back

The climate at the poles of the earth is cold, meaning that Antarctica used to be closer to the equator.

Front

At what rate do continents continue to move?

Back

About 2 centimeters per year

Front

Why don't present day continents fit perfectly together?

Back

Weathering and erosion of coastlines

Front

What kind of plate boundary is shown here? Options: divergent, convergent, transform, submergent

Back

transform
