In general as elevation increases from the ground up what happens to atmospheric pressure?

Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.

What happens to temperature and available moisture as elevation increases?
In general they both decrease.
Is it true that air pressure increases as altitude increases?
No, in general the opposite is true.
When the air pressure is low the freezing point of water decreases or increases?
According to my General Science book I think it increases.
How air pressure is a factor for predicting weather?
In general High Pressure promotes atmospheric stablity (clear sunny weather) and warmer temperatures, while Low Pressure promotes atmospheric instablity (storminess) and somewhat cooler temperatures. In low pressure systems in the northern hemisphere air rotates in a counterclockwise direction and moves upward. This promotes cloud formation cooler temps and sometimes storms. In high pressure systems in the northern hemisphere air rotates in a clockwise direction and moves downward (subsidence). This inhibits cloud formation and usually increases temperatures.
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
What is the relationship between elevation and temperature?
As a general rule in the atmosphere, the higher the elevation the lower the temperature. However, certain atmospheric conditions may produce an 'inversion', where temperature increases with elevation.
What is atmospherical pressure at higher and lower altitude?
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)

What is function of a barometer?
To measure atmospheric pressure. In general, higher atmospheric pressures (also called "higher barometric pressure") is generally associated with good weather, while low or falling pressure is generally linked to rain or bad weather.
What general statement can be made about the relationship between air pressure and altitude?
Air pressure decreases as altitude increases.
When the air pressure is low the freezing point of water decreases or increases?
According to my General Science book I think it increases.

How does the boiling temperature of water change with altitude?
Depending on the altitude the boiling point will differ. This calculator will give you the boiling point of the altitude that you desire to discover: http://www.csgnetwork.com/h2oboilcalc.html
Defined as the point as which liquids vapor pressure equals the atmospheric pressure?
The normal boiling point(also called the atmospheric boiling point or the atmospheric pressure boiling point)is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere.The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa).General Useful Information:The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure, but the environmental pressure may or may not be equal to the atmospheric pressure at sea level, 1 ATM.If the surrounding environmental pressure is less than atmospheric pressure, then the boiling point is less than the normal boiling point.If the surrounding environmental pressure is greater than atmospheric pressure, then the boiling point is greater than the normal boiling point.At the boiling point, adding enough heat to the liquid will cause the liquid to vaporize (that is boil or form a gas).
Why does atmospheric pressure start to decrease around midnight when with the temperature decrease pressure should increase?
The reason for temperature being lower in high altitude regions (as compared to places at sea-level) is due to the decrease in atmospheric pressure as we go up in altitude. So decrease in atmospheric pressure causes the temperature to decrease, which might be a reason for the decreased pressure at night. --- Diurnal temperature fluctuations vary by location, but follow a twice-daily cycle of general rise and fall, corresponding to the "atmospheric tide" induced by the eastward rotation of the planet.
