How would gas exchange be affected at the top of a tall mountain where air pressure is lower and there is less oxygen then lower elevations?
At high altitudes, atmospheric pressure is lower. Therefore, the partial pressure (partial oxygen) is lower. As partial pressure of oxygen goes down, the body's desire for oxygen goes up.
Is air pressure greater at the top of a mountain than at lower elevations?
No, it is greater at the lower elevations.
Is air pressure greater at the top of a mountain than at the lower elevations?
No, it is greater at the lower elevations.
What has higher pressure a mountain or a valley?
A valley typically has higher pressure compared to a mountain. This is because air tends to sink into valleys due to gravity, leading to slightly higher air pressure at lower elevations. In contrast, mountains have lower air pressure at higher elevations due to the thinner atmosphere.
How would gas exchange be affected at the top of a tall mountains where air pressure is lower and there is less oxygen than at lower elevations?
trees can't survive on a mountain beacuase trees need carbon dioxide and because the most mamamls don't live in the mountains because of low oxgen levels there is less carbon dioxide. As a result, there wouldn't be mush gas exchange and the tree most likely would die. People who live in the mountains have more
Why is air pressure on a high mountain is less than on the lowland?
Air pressure decreases with altitude because there are fewer air molecules at higher elevations. As you climb a high mountain, the weight of the air above you decreases, resulting in lower air pressure.
What is affected by surface elevation water vapor and temperature?
Surface elevation can affect air pressure, which in turn influences the amount of water vapor the air can hold. Higher elevations typically have lower pressure and cooler temperatures, leading to lower water vapor capacity. This can result in drier and less humid conditions at higher elevations compared to lower elevations.
Is the air pressure greater at the peak of the mountain or the base?
The air pressure is greater at the base of the mountain compared to the peak. This is because the weight of the column of air above decreases as you move higher up in the atmosphere, leading to lower air pressure at higher elevations.
Why does the temperature change when you go up an mountain?
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.
Why does the top of a mountain have greater air pressure?
The top of a mountain has lower air pressure, not greater air pressure, compared to lower elevations. This is because the higher you go in elevation, the thinner the atmosphere becomes, leading to lower air pressure due to decreased atmospheric density.
How would gas exchange be affected at the top of of a tall mountain where air pressure is lower and there is less oxygen than at lower elevations?
At higher elevations with lower air pressure, there is less oxygen available for gas exchange in the lungs. This can lead to decreased oxygen saturation in the blood, causing difficulty breathing and potentially leading to altitude sickness. To compensate, the body may increase breathing rate in order to try to obtain more oxygen.
Is there really less oxygen at higher elevations?
Yes, the air pressure decreases at higher elevations which results in a lower concentration of oxygen molecules per unit volume of air. This can make it more difficult for people to breathe at higher altitudes.
