Atmospheric pressure changes .

a. more rapidly in the vertical direction than in the horizontal
b. more rapidly in the vertical direction over land than over the ocean
c. at the same rate in the horizontal and vertical directions
d. more rapidly in the horizontal direction than in the vertical

b. more rapidly in the vertical direction

Explanation:

Atmospheric Pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation.

Pressure decreases with increasing altitude because at higher altitudes both the height of overlying air column and its density decreases. Hence the answer.

1/0.14nm = 10^10/1.4 a lot

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
