What does Wegener's hypothesis of continental drift state?

• the continents do not move

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass

• Earth's surface is made up of seven major landmasses

What is Pangaea?

• the name of the supercontinent that existed millions of years ago

• the name of a German scientist

• the name of an ancient fossil

• another name for continental drift

What type of evidence did Alfred Wegener NOT use to support his continental drift theory?

• evidence from fossils

• evidence from human remains

• evidence from climate

• evidence from landforms

Why did most geologists reject Wegener’s idea of continental drift?

• they were afraid of a new idea

• Wegener could not identify the force that could move the continents

• Wegener used several different types of evidence to support his hypothesis

• Wegener was interested in what Earth was like millions of years ago

In what process does molten material rise from the mantle and erupt along mid-ocean ridges?

• continental drift

• seafloor spreading

• volcanic eruption

• earthquake

How did scientists discover that rocks farther away from a mid-ocean ridge were older than the rocks near it?

• by observing eruptions of molten material on the ocean floor

• by measuring how fast seafloor spreading occurs

• by determining the age of rock samples by drilling on the seafloor

• by mapping rocks on the seafloor using sonar
