Why is it colder on top of a mountain than it is at a beach?
A. The air on the mountaintop is at lower pressure.
B. The mountaintop is closer to the sun.
C. The gas molecules collide less at the beach.
D. The air on the mountaintop is at higher pressure.
E. The gas molecules collide more on top of the mountain.

The earths atmosphere keeps heat in and the cold out. However, the higher you go the colder it gets. That's because the atmosphere is thinner the higher you go. The atmosphere is made of several layers but the one that deals with your question is the Troposphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. As you climb higher in this layer, the temperature drops from about 17 to -52 degrees Celsius. Almost all weather is in this region.

ummm....A makes sense but so does B.. if it has less pressure then the molecules wouldnt be as active either.. thusly making it colder because of less molecular friction... Right?
Hm. School needs to start again.

None of your proposed answers A through E is correct.
The temperature of the atmosphere is not a function of the pressure.
The temperature gradient of -6.5°C / -6.5K per 1000 meters of altitude is not influenced by pressure.
The temperature gradient is -3.57°F per 1000 ft of altitude for the nation which did not make it to think in international units of measurement in daily life.

Hmmm...
FIRST: Assume that one of the answers is correct.
(This is not a scientifically sound assumption BTW.)
D & E are scientiffically incorrect.
re: C - Less collision implies less motion implies lower temperature.
B is scientifically correct but it doesn't account for cooler temperature.
THEREFORE:
The answer must be A if our assumption is correct.

A is your answer by the ideal gas law: PV = nRT
B is false as the difference between the distances is insignificant.
C, D, and E are all false.
