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.

No, it is actually one of the slowest spreading ridge on Earth. The slowest ridge is the Southwest Indian ridge, while the East Pacific Rise is the fastest.
If true, it would indicate that the divergent plates of the eastern Pacific are spreading at a faster rate than the plates of the Mid-Atlantic Ridge.

Very slowly on the order of tens of millimetres per year. For example the Mid Atlantic Ridge is spreading at around 25 mm/yr where as spreading centres in the Pacific tend to be faster with rates up to around 100 mm/yr.

Pacific Ridge School was created in 2007.
The Mid-Atlanic Ridge is the divergent boundary that is responsible for seafloor spreading. Consisting mostly of divergent boundaries, with transform faults as well, this is the site where new oceanic crust is added, increasing the size of the ocean. This location is dotted with underwater volcanoes as igneous basaltic magma is added to fill in the gap left as the oceanic plates drift away.
Iceland is a volcanic island on the midatlantic ridge, separating the North American Plate to the west from the European Plate to the east.
A spreading ridge, where two plates diverge.
