What causes the air to be thinner the higher you go?

    The air is denser at sea level because air compresses and the weight of all the air above us compresses all around us. As you go up a mountain the air becomes less compressed and thus the air is thinner. There is less pressure because for a volume of air there are a number of molecules (including oxygen) present and with less volume of air there are less molecules.
