QUIZ A--Unit 2: L.1-3: Plate Tectonics/Earth's Dynamic Processes

Who proposed the hypothesis of continental drift?

• Alfred Wegener

• Isaac Newton

• Marie Curie

• Charles Darwin

What evidence did Alfred Wegener observe to support his continental drift hypothesis?

• Similarities in the shapes of clouds and rivers

• Similarities in the shapes of continents and continental shelves

• Similarities in the shapes of stars and galaxies

• Similarities in the shapes of animals and plants

What evidence supported continental drift from rock formations and mountain chains?

• Similar ages, structures, and chemistry of rock formations on different continents

• Similar ages, structures, and chemistry of rock formations on different asteroids

• Similar ages, structures, and chemistry of rock formations on different planets

• Similar ages, structures, and chemistry of rock formations on different moons

What evidence from glacial features and coal deposits supported continental drift?

• Tsunamis and landslides

• Earthquakes and fault zones

• Volcanic eruptions and lava flows

• Glacial grooves and sediments

What did the fossils of Glossopteris plant found on separated continents support?

• The theory of relativity

• The cell theory

• Wegener's hypothesis of continental drift

• The law of gravity

Why were scientists initially skeptical of Wegener's continental drift hypothesis?

• Too many tools and advanced technology

• Too much evidence and clear explanations

• Lack of measurable speed and unknown driving forces

• Too many measurements and known driving forces

When did scientists explore the seafloor using echo sounders?

• Late 1960s

• Late 1940s

• Early 1900s

• Mid 1950s

What did scientists discover on the seafloor using echo sounders?

• Lakes and rivers

• Mountains and valleys

• Deserts and forests

• Mid-ocean ridges and ocean trenches

What did scientists use rock samples to create, revealing stripes on the seafloor?

• Topographic maps

• Isochron maps

• Political maps

• Weather maps

What process explains the formation of new oceanic crust and its spreading along mid-ocean ridges?

• Volcanic eruptions

• Seafloor spreading

• Plate tectonics

• Continental drift
