Describe the ages of rocks on the ocean floor around a mid ocean ridge.

• The rocks are the same age across the ocean floor.

• The rocks are younger closer to the ridge and older farther away.

• The rocks are older closer to the ridge and younger farther away.

• There is no pattern to the ages of rocks around a mid ocean ridge.

Why does the age of rocks get older the farther away from the ridge they are?

• New crust is less dense and floats on top of the ridge.

• Older crust is thicker so it moves toward the continents.

• Older crust forms at the continents then moves toward the ridge and melts to form new crust.

• New crust forms at the ridges and then moves away from the ridges as new crust continues to form.
