Exam 3 Review

How do scientists know the seafloor is spreading? Choose the best answer.

• Earthquakes occur at mid-ocean ridges.

• The ocean floor is covered in fossils.

• Magnetic patterns in oceanic crust mirror each other on either side of mid-ocean ridges.

• Volcanoes erupt only in the middle of the ocean.

In a divergent plate boundary, plates move: Choose the best answer.

• Towards each other

• Away from each other

• Side by side

• Overlapping one another
