What causes seafloor spreading to occur?

• Old crust is destroyed at divergent boundaries.
• New crust forms at divergent boundaries, pushing old crust outwards.
• Old crust pushes new crust towards divergent boundaries.
• New crust forms as plates move over hotspots.

What feature forms near divergent boundaries between two pieces of oceanic crust?

• Mid-ocean ridge
• Non-volcanic mountain
• Continental rift valley
• Trench

What causes paleomagnetic stripes to form on the ocean floor?

• Different types of rock form in different locations on the ocean floor.
• Earth's magnetic field reverses while seafloor spreading occurs.
• Earth's magnetic field has been getting stronger over millions of years.
• Earthquakes cause Earth's magnetic field to reverse.

What feature forms near divergent boundaries between two pieces of continental crust?

• continental rift valley
• non-volcanic mountain
• mid-ocean ridge
• canyon
