Plate Tectonics/Continental Drift

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

Weathering and erosion are driven either directly or indirectly by what?

• Wind

• Water

• The sun

• Climate change

Who first developed the Theory of Plate Tectonics

• Alfred Einstein

• Carl Jung

• Thomas Edison

• Alfred Wegener

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

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

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

• The climate at the poles of the earth was once warm

• The equator used to be at the poles of the earth

• The earth's orientation was once such that the poles of the earth were closer to the sun

Glacial deposits are found in what areas, indicating a different climate at one time?

• Oceans

• Tundras

• Deserts

• Deciduous forests
