TEST Plate Tectonics

Where is the Ring of Fire located? Use map 2

• It is located along the Mid-Atlantic Ridge
• It surrounds the Pacific & Nazca plates
• It is on the western side of the Indo-Australian plate?
• It surrounds the South American plate

What type of boundary exists between the western side of the North American plate and the eastern side of the Pacific plate? Use map 3

• Convergent
• Divergent
• Transform
• Subduction

What type of boundary is located between the Philippine & Pacific plates? Use map 3

• Convergent
• Divergent
• Transform
• Subduction

Which boundary will cause sea floor spreading? Use map 4

• Nazca Plate & South American Plates
• Indian Plate & Eurasian Plate
• South American Plate & African Plate
• Australian Plate & Pacific Plate

At which boundary would a subduction zone be found? Use map 4

• Indian & Eurasian Plates
• South American & Nazca Plates
• North American & Pacific Plates
• African & Indian Plates

What causes plates to move along the surface of the earth?

• Dense rock floating the surface of the crust
• Convection currents in the mantle 
• The sinking of the asthenosphere
• The plasticity of the lithosphere

What causes convection currents?

• Hot materials rise to float above cooler, denser materials
• Hot materials sink below cooler materials
• Cold rock rises to float above less dense rock
• Cold rock becomes less dense than the center of the earth 

At a divergent boundary where is the youngest rock found?

• Far away from the boundary.
• On the boundary.
• A few hundred feet from the boundary.

Why wasn't Alfred Wegener's idea of continental drift accepted before his death?

• Wegener needed more evidence of continental drift.
• Wegener couldn't explain how continents move, which we now know are convection currents.
• Wegener did not have rock evidence.
• Wegener could not explain how plants grew in Antartica.

Who proposed their hypothesis of the continental drift in 1912?

• Albert Einstein

• Alfred Wegener

• Dmitri Mendedleev
