I agree in most of the potential tag synonyms @bon sugested to merge in 2016.
mineralogyIt is anoying to enter both tags each time a mineral is related to the question. And we banned id-my-mineral questions.
rocks. Same, I would merge with
fossilsSame, I would merge with
climateSame, I would merge with
crystalsSame, I would merge with
oceanSame, I would merge with
oceanography. (this is in the list to vote)
plate-tectonicsare not the same.
seismologyare the same, but not the same as
glacierI wouldn't merge it with
glaciollogyas glaciollogy is a science that covers more things than glaciers and the tag would be more specific for questions about glaciers around the world.
ice-ageare the same if I am not wrong. Not sure the one should be used.
mountain-buildingis an unnecesary tag, as it is
orogenythe correct term, but
mountainsis usefull for questions about mountains and not his genesis.
hidrogeologyare separated disciplines.
petrographyis used in microscope images and
petrologyis a more global science.
- Not sure for the others.
Most of these sugestions of merging are not in the synonym tags queue.
I have not the privilege to sugest merges and I am not sure if they were sugested and disaproved in 2016, but if not, should someone do it and we start to vote as bon's post has 5 upvotes?
The problem to do effective the merges is that to vote you need to reach 1,250 reputation points and: "...a total answer score (total upvotes minus total downvotes) of 5 or more on the tag". We have not people with both requisites and active in the site for all the merges enough to do the merges quickly, but in my opinion it would be nice the sugestions were in the queue to be merged progressivelly in the future if the community agree.
