What would happen if gravity suddenly doubled on Earth, but the mass of the
atmosphere did not change?
(a) Surface pressure would stay the same but the density would increase.
(b) Surface pressure would increase but the density would stay the same.
(c) Surface pressure and density would both increase.
(d) Surface density and pressure would stay the same because the atmosphere is
in hydrostatic balance.
