You really mean that there are less oxygen and other gas particles in the same space then when you are lower. This happens because the higher you are, the less air you have on top of you, therefore the weight (pressure) is lower and the gas is compressed less, which is why it occupies more space.
yes, the higher the altitude the thinner the air, thus the less oxygen in the air.
air grows thinner so it gives less pressure on the earth's surface
air gets thinner > harder to breathe
At high altitude the air is thinner because of the gravitational pull of the Earth that draws air molecules towards its centre. This making the air denser near the surface and thinner as altitude increases. The less dense the air is, the less oxygen the air contains.
the altitude. At higher altitude it is harder to breather because the air is thinner.
Better fuel economy. The air is thinner at higher altitudes.
because as we go up wards from the surface of the earth,air becomes thinner.
Air is compressed (squeezed) by the air above it (due to gravity), the higher you go, the less air there is above you.
air grows thinner so it gives less pressure on the earth's surface
It decreases because as you move up in altitude the air becomes thinner making it colder.
There is less drag at altitude than at sea level. The air is thinner at altitude.
As at higher altitudes the density of air decreases, which means that air is thinner. As a result golf ball travels farther at a higher altitude because of decreased drag on the ball.
