hemispherical
Like a dome
Hemispherical describes something shaped like half a sphere—a dome or bowl form created by cutting a ball in two.
The term applies to physical objects like hemispherical domes on buildings or hemispherical bowls, as well as to conceptual divisions like the Earth's hemispheres.
In technical contexts, it often describes the geometry of lenses, mirrors, or acoustic spaces designed to distribute light or sound evenly.
