How do changes in atmospheric pressure affect people at high altitudes?
It keeps us all from blowing up and popping like balloons, and it also makes it possible for us to breathe.
The words high altitudes harsh climate and only cold hardy species describe which US ecosystem?
It describes the Alpine Tundra.
What type of air mass forms off the southeast coast of the us?
An air mass that forms off the southeast coast of the us is referred to as Bermuda High. This happens in summer and in fall.
How much us high relative humidity?
Relative humidity is 100% of water vapor in the air. When that happens dew forms.
What is it called when air presses on us?
air has mass
Why must airplanes be pressurized?
At the high altitudes which airliners fly in, there is less dense. Since air is good for us humans, the cabin is pressurized in order to provide enough air to breathe.
Why are airplanes pressurized?
Most air planes are pressurized, because at high altitudes, the air pressure is less than humans can handle, which causes us to black out. Bad vacation when your pilot blacks out at 30,000 feet!
How do changes in atmospheric pressure affect people at high altitudes?
It keeps us all from blowing up and popping like balloons, and it also makes it possible for us to breathe.
Why is there less oxygen in higher altitudes?
The higher you go the thinner the air gets. If you go to high, you could die from lack of air. > Jet fighters dont have pressurised cabins ( as commercial flights do) 25,000 feet is the crucial point, the lungs are incapable of absorbing oxygen at such low air pressure, a pressure demand mask overcomes this problem.
The words high altitudes harsh climate and only cold hardy species describe which US ecosystem?
It describes the Alpine Tundra.
How high is an aircraft in US before you see the white smoke?
That isn't white smoke, it's water vapor that is condensed out of the air by the passing of the aircraft. This is called a "contrail," which stands for condensation trail. The altitude depends upon the relative humidity and the temperature, which vary from hour to hour. Generally, this only occurs at very high altitudes.
What type of precipitation does cirr us clouds form?
Generally, none. Cirrus cloud is formed of ice particles at high altitudes so there is no precipitation which reaches the ground.
How does the air force affect the lives of us citizens?
they help us by protecting us by air. just like the navy, army, air force, marines, etc.
At higher altitudes there is less oxygen in the air How might the composition of blood in people living in these higher altitudes differ from the blood in people living at sea level?
In an effort to take in as much Oxygen is available to us, the human body increases the number of RBCs in the system, which also would reflect in a higher Haemoglobin count for such people.
Can someone finished high school outside US join air force?
No
What precautions do pilots have to take if they fly above 45000 m?
Precautions when flying at high altitudes would be a pressure suit and oxygen /masks. But civilian flights do not ascend over 43,000 feet in the US.
Why the pressure vareis from moutanins to land?
High up on the mountains, there is less air above us. It is the air that causes the pressure.
