Plate Tectonics video remediation Quiz

Who proposed the idea of continental drift and the supercontinent Pangaea?

• Marie Tharp

• Alfred Wegener

• Robert Dietz

• Harry Hess

What evidence did Alfred Wegener use to support his theory of continental drift?

• Fossils, rock types, and mountain ranges

• Seafloor mapping, paleomagnetism, and crust subduction

• Satellite data, plate motion, and continental collisions

• Physiographic map, echo sounder, and seismic surveillance

Who published the first physiographic map showing the physical features of the Atlantic ocean floor?

• Robert Dietz

• Alfred Wegener

• Marie Tharp

• Harry Hess

What did Harry Hess propose about the seafloor in 1960?

• The seafloor is formed by subduction of oceanic crust

• The seafloor is created by continental collisions

• The seafloor is like a giant conveyor belt with seafloor spreading

• The seafloor is a flat featureless plain

What evidence did Fred Vine and Drummond Matthews use to confirm the theory of seafloor spreading?

• Fossils, rock types, and mountain ranges

• Seafloor mapping, paleomagnetism, and crust subduction

• Magnetic barcode of black and white stripes

• Satellite data, plate motion, and continental collisions

What is the name of the boundary where plates are moving away from each other?

• Subduction zone

• Divergent boundary

• Transform boundary

• Convergent boundary

What type of boundary is the San Andreas Fault along the west coast of North America?

• Subduction zone

• Divergent boundary

• Transform boundary

• Convergent boundary

What happens when two continental plates collide?

• The plates slide horizontally past each other

• One plate is subducted beneath the other

• Both plates are subducted into the mantle

• The crust is compressed, folding and pushing up mountain ranges

What technology is used to detect plate motion by recording changes in Earth's surface?

• Echo sounder

• Physiographic map

• Seismic surveillance system

• Satellites

What is the main focus of current research on plate tectonics?

• Comparing Earth's plate tectonics with Venus

• Exploring the cause of the outer shell cracking

• All of the above

• Studying the evolution of complex life
