Discussion
Which requirement must hold for pressure to serve as a vertical coordinate?
Answer: A
A quantity can replace height as a coordinate only if it varies monotonically along the vertical, and hydrostatic balance with positive density guarantees exactly that for pressure. Isothermality, geostrophy and a particular temperature gradient are all irrelevant to the requirement. The monotonic decrease is why hydrostatic balance is a prerequisite for the whole pressure coordinate framework. Working one numerical case through both cases side by side fixes the distinction better than any rule of thumb.
