ยง Submersions and immersions

Who in the world decided their names? I remember which is which based on the sound. "Submersion" is "surjective", "immersion" is "injective". But really, the naming makes no sense. I can intuitively submerge a ring (a 1D object) into the ocean (a 3D object). so if anything, I'd expect submersions to be locally injective. You can only submerge XX into YY if YY is "larger" than XX. The definition asks for the precise opposite!
