The new rocks don't form from nothing. They form either from material from older rocks that were broken down, or magma that originates inside Earth. As magma rises and erupts as lava from volcanoes the crust will sink down slightly, filling in the space left behind. New oceanic crust is formed as lava erupts at mid-ocean ridges, but at the same time old oceanic crust slides down into the mantle at subduction zones.
