At this point land appears! (3,5)

I believe the answer is:

sea level

I'm a little stuck... Click here to teach me more about this clue!

'at this point land appears' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'at this point' is the wordplay.
'at' becomes 'sea' (I am not sure about this - if you are sure you should believe this answer much more).
'this point' becomes 'level' (synonyms).
'sea'+'level'='SEA-LEVEL'

Can you help me to learn more?

(Other definitions for sea level that I've seen before include "It's used in reckoning land elevation" , "0 feet?" , "Altitude reference point" , "Standard for measuring map heights" , "Base from which height of aircraft is measured" .)
