Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
A Divergent Boundary.

New oceanic crust is created at spreading centres. These may also be termed divergent or constructive plate boundaries or Mid-Ocean-Ridges.
No. Many plate boundaries are on the seafloor far from continents and several are well within continents.

Because it only gets larger in one direction by getting smaller in another. In the case of ocean ridges, the 'other place' is wherever the crust has subducted into the natle at a plate boundary.

On the seafloor. Yes, the mid oceanic ridges are all divergent boundaries.

Seafloor Spreading

No. Many plate boundaries are on the seafloor far from continents and several are well within continents.
At divergent plate boundaries the spreading of the tectonic plates results in the reduced pressure of the underlying magma. As the spreading continues, lava fills in the area of spreading and cools, becoming the newest addition to the seafloor. This process occurs at a steady rate ranging from a few centimeters to several centimeters of new sea floor each year. However, at a different location opposite the newly formed seafloor are convergent plate boundaries where land and seafloor is destroyed to make room for new seafloor.
