Isostatic sea level change help

hi <3
Can somebody help me with isostatic sea level change?
I know that
- when the height of the land increases the sea level locally decreases and visa versa
but i dont understand how
wouldn't high land make less room for the sea and therefore increase the sea level? like if you put your hand in a cup of water the water rises
any help appreciated :smile:

I'm not sure if this will make sense but I'll try my best. so basically although the height of the land is increasing, there isn't a change in the mass or amount of land it is just lifting upwards, kinda like a seesaw. when you put your hand in a cup you displace the water bc you are occupying more space. hope that helped!! :smile:
