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

• Mid-ocean ridge

• Non-volcanic mountain

• Continental rift valley

• Trench

where two plates are moving apart under the ocean, magma comes up to create new crust

• ridge

• divergent boundary

• convergent boundary

• plate boundary

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.

When a divergent boundary occurs underneath the ocean, it's called a:

• Rift Valley

• Ocean Ridge

• Subduction Zone

• Fault Block Mountain
