the tectonic plates under the earths surface
tsunami
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.
sea floor spreading or divergent boudary
The ocean floor moves in a horizontal direction due to tectonic plate movements. This movement can be divergent (moving apart), convergent (moving towards each other), or transform (moving past each other). This movement is driven by underlying mantle convection currents.
Mid ocean ridges are the direct result of sea floor spreading.
The mid-ocean ridge is almost in all of the oceans
The topography of the ocean floor
which landforms are on the ocean floor
As the oceanic lithosphere moves away from a mid-ocean ridge, it cools and thickens. This process causes the ocean floor to become older and denser, resulting in its gradual subsidence. The farther it gets from the ridge, the deeper the ocean floor becomes due to the increased thickness and weight of the lithosphere.
The ocean floor is not smooth.The ocean floor is made up of rocks, ledges and ditches.
No, the mid-ocean ridge is actually where new oceanic crust is formed through volcanic activity. As the crust moves away from the ridge, it becomes older. The oldest oceanic crust is found near the edges of the ocean basins.
blank are found on the ocean floor
