When describing an everyday item or shape, are there any significant differences between dome and hemisphere/semi-sphere, or they are interchangeable?
From my understanding, dome is more an architectural term and hemisphere is more a geological term. But outside their specialties, I found the line between the two is vague when describing everyday items or shapes. Can I use them interchangeably for general use?

If I were going to be picky about it, I'd say that a hemisphere must be half of a sphere, while a dome can be any reasonable percentage of a hemisphere. (I.e. big enough to be clearly rounded; if you take a super-small slice off the top of a sphere, it will look basically flat.) For instance, the Astrodome and the Metrodome were both very clearly much less than half of a sphere (the Metrodome wasn't even entirely round!). In ordinary usage, though, I try not to be too picky. :-)

A dome doesn't even need to be spherical; it might be parabolic for instance.

Another difference is that we call it the Western Hemisphere, not the Western Dome. I'm not sure if there's a circumstance where both words can be used equally. In what situation do you think they could be used interchangeably?

I think of a dome as enclosing a hollow space, whereas a hemisphere just describes the outside shape and says nothing about what’s inside.

@Hellion & Spencer Good call-outs, essentially you guys are saying dome doesn't to be spherical or exact half of a sphere.
