In plate tectonics a spreading boundary is where two geological plates are moving in opposite directions. The gap is filled with magma from below, an example is the Mid Atlantic ridge
Spreading is generally thought of when speaking of sea-floor spreading. Sea-floor spreading takes place at the mid-ocean ridge where two oceanic plates are spreading/pulling apart from one another.
Typical rates of spreading average around 5 centimeter (2 inches) per year.
rate of spreading for stripe = width of stripe / time duration If a magnetic strips is 60 km wide and formed over 2 million years, then the rate at which spreading formed the was 30 km/m.y. The rate is equivalent to 3 cm/year. Spreading added an equal width of oceanic crust to a plate on the other side of the mid-ocean ridge, so the total rate of spreading across the ridge was 60 km/m.y. (6 cm/year), a typical rate of seafloor spreading.
Oceanic currents themselves do not directly cause seafloor spreading. Seafloor spreading is primarily driven by tectonic forces, specifically the movement of tectonic plates away from each other at mid-ocean ridges. This movement leads to the upwelling of magma from the mantle, creating new oceanic crust at the spreading center. Ocean currents can affect the distribution of heat and nutrients in the ocean, but they do not play a direct role in the process of seafloor spreading.

spreading rumours
it is spreading because of the effect on it
'Spreading' is a verb because it is an action.
sea floor-spreading..;)
Neither is spreading faster. They are both spreading at the same rate.
The spreading of a desert is called desertification.
we can stop spreading by giving tt to a child
They proved that the seafloor was spreading.
Spreading boundaries are places where two plates move apart.
