A "derivative work" is a work based upon one or more preexisting works, such as a translation, musical arrangement, dramatization, fictionalization, motion picture version, sound recording, art reproduction, abridgment, condensation, or any other form in which a work may be recast, transformed, or adapted. A work consisting of editorial revisions, annotations, elaborations, or other modifications which, as a whole, represent an original work of authorship, is a "derivative work".Your second, third, and fourth pictures of the sunset are not based on the first picture, they're based on the sunset which, presumably, nobody has claimed the copyright to. They're not derivative works just because they're pictures of the same thing, or really similar pictures, derivative works actually incorporate the original work in some meaningful way. For example, if you were to take your first sunset photograph and then draw a pterodactyl onto it, the new (prehistoric) sunset could be a derivative work.

If it has a license it's not "public domain"
As the copyright owner you can do pretty much what ever you want with the licensing of your photos.
For example you could pick a CC-Non-commercial license as the default licenses for pictures you post, but also make it clear you will also license the same photo for commercial purposes if so desired.
You could also put photos in the true public domain except for the photos that you wish to keep commercial terms on.
1) To answer your questions, pretty much each action you do creates a new copywritten work, even if they are almost exactly the same.
2) Why would someone buy your photo if a really similar one was in the true public domain?
Many times someone want to have clear ownership or licensing rights, that's something people will pay for.
