What is the process in which the sea floor separates and moves in opposite direction is known as?
divergent
How do strip of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
How do rocks along the central valley of the mid-ocean ridge provide evidence of the sea-floor spreading?
Magnetic field direction.
Seafloor spreading occurs because?
Because as the sea-floor spreads apart, magma is forced upward and flows from the cracks. It becomes solid as it cools and forms new sea-floor. As new sea-floor moves away from the mid-ocean ridge, it cools, contracts, and becomes denser.

Is mid-ocean ridge is how the direction of sea-floor spreading?
It spreads away form the ridges
