New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.

What causes ocean floor features to form
Sea-floor Spreading through a mid ocean ridge.
sea-floor spreading
what is the loose material that settles on the bottom of the ocean called
Sedimentation.
The uplifted sea floor results from convection currents which rise in the mantle as magma at a linear weakness in the oceanic crust, and emerge as lava, creating new crust upon cooling.
