yes, as you go farther up from the sea level, the air will become thinner.
From what I recall, the air at the bottom of a mountain is usually warmer, wetter, and more oxygenated. The air at the top gets less of these three depending on as high up as you go.
Yes, as you go up a mountain, the air pressure will become less. This is because the weight of the air above decreases as you gain elevation, resulting in lower atmospheric pressure.
The air pressure slowly decreases as you rise in altitude.
No, but there is less oxygen. This makes breathing harder.
When an air mass encounters mountains it cannot go through them, nor down into the ground, so the only direction left to go is up.
Most often, the air at higher elevations is cooler than the air at lower elevations. The act of your climbing the mountain has no effect on it.
Air pressure at any altitude is determined by how strongly gravity forces the surrounding air molecules together and downward. The higher the altitude the less pull gravity exerts on the air molecules, and consequently, the air pressure decreases. So, as you climb a mountain, the higher you go, the lower the ambient air pressure.
As you go up a mountain, the air pressure decreases, which can lead to lower oxygen levels. This may cause difficulties breathing and can lead to altitude sickness. The temperature also tends to drop as you ascend.
At higher altitudes, the air pressure surrounding the bag of chips decreases while the air pressure inside the bag remains the same. This pressure difference causes the bag to expand and appear inflated like a balloon.
A 1inch by 1inch column of air from the edge of the atmosphere to sea level weighs 14.7 pounds, 80% of that is in the Troposphere. As you go up, the air within that column has less mass, making the air "thinner", and air pressure goes decreases.
As you drive up a mountain, air pressure decreases because atmospheric pressure decreases with higher altitude. As you drive down the mountain, air pressure increases because the weight of the air above you increases as you descend to lower altitudes.
The temperature changes as you go up a mountain due to the reduction in atmospheric pressure with increasing altitude. This drop in pressure causes the air to expand and cool, resulting in colder temperatures at higher elevations.
