Seafloor spreading at midocean ridges produces and adds new area to the oceanic lithosphere. Thus, plate change size over time. Some grow, some shrink and even disappear if mostly oceanic. Since areas of continental do not shrink and some oceans open, some area must be lost because the Earth isn't changing size
