Plate Tectonics Evidence Quiz

What is the main focus of this video?

• The evidence for plate tectonics

• The history of plate tectonics

• The mechanism of plate tectonics

• The exploration of the ocean floor

What did Alfred Wegener propose in his theory of continental drift?

• Continents are stationary and do not move

• Continents have always been in their current positions

• Continents were once joined together in a supercontinent called Pangaea

• Continents move randomly and independently

What is the first piece of land-based evidence for plate tectonics?

• Fossil distribution

• Rock age type and structure

• Climatology

• Mountain chain formation

What does the matching age, type, and structure of rocks on different continents suggest?

• The continents were formed at different times

• The continents were formed by different processes

• The continents were once joined together

• The continents have always been separate

What is the significance of finding the same fossils on different continents?

• It suggests that animals can travel long distances

• It proves that evolution is a random process

• It supports the theory of continental drift

• It shows that continents have always been separate

What does the distribution of polar plants suggest about the movement of continents?

• Continents have always been in their current positions

• Polar plants can survive in any climate

• Continents were once located near the equator

• Polar plants can migrate long distances

What did Harry Hess discover about the ocean floor?

• The ocean floor is made of different types of rock

• The ocean floor is completely flat and featureless

• The ocean floor has a continuous mountain range

• The ocean floor is covered in fossils

What is the pattern observed in the topography of the ocean floor?

• Random and unpredictable

• Aligned with the continents

• Symmetrical around the equator

• Irregular and chaotic

What is the main mechanism of plate tectonics?

• Continental drift

• Volcanic eruptions

• Seafloor spreading

• Tectonic plate collisions

What is the age of the seafloor farthest from the mid-ocean ridge?

• Younger than the seafloor near the ridge

• Older than the seafloor near the ridge

• The same as the seafloor near the ridge

• Impossible to determine
