Why do surface pressure for inland stations need to be corrected before making a weather map?
They need to be adjusted for altitude, so that all stations report an equivalent sea level pressure. If the raw station pressures are mapped the synoptic features can be obscured by topography. The pressure in Amarillo is always lower than the pressure in Dallas because of the difference in altitude. By correcting both to sea level, significant information about state of the atmosphere can be seen.
Why is air pressures greatest at ground level?
It is not, air pressure is greatest at sea level. This is because the air pressure is caused by the weight of the air above you and at sea level the depth of the air column above you is at its maximum.
What range does sea level pressure values generally fall in?
980 mb to 1045 mb (Those are the values for deep low-pressure systems and strong high-pressure systems). The average sea-level pressure is 1013 mb. The highest and lowest sea level pressures record are 1084 mb and 870 mb.
What is uncorrected barometric pressure?
Uncorrected barometric pressure is essentially BP at sea level. When you see a weather report (Weather Network etc.) the BP you see is corrected for elevation.
Stable molecules that contain carbon and are formed below sea level under low temperatures and high pressures are called?
You're probably thinking of methane hydrate-clathrate.
Weather pressure line?
An isobar is a line of equal pressure on a map . In meteorology, the barometric pressures shown are reduced to sea level, not the surface pressures .
The strongest hurricanes have central sea level pressure around 500 mb. True or false?
False - the strongest hurricanes have pressures a little bit under 900mb (average sea level pressure is 1013mb).

Can water boil 100 degrees Fahrenheit?
Yes, if you lower the pressure to about 6.6 kPa (normal atmospheric pressure at sea level is around 101 kPa; you'd find pressures like this at an elevation of about 12 miles above sea level).

980 mb to 1045 mb (Those are the values for deep low-pressure systems and strong high-pressure systems). The average sea-level pressure is 1013 mb. The highest and lowest sea level pressures record are 1084 mb and 870 mb.

At sea level do you find low atmosphere pressure?
Low pressure and high pressure are not absolute. You find those pressures at any place. http://en.wikipedia.org/wiki/Atmospheric_pressure
Stable molecules that contain carbon and are formed below sea level under low temperatures and high pressures are called?
You're probably thinking of methane hydrate-clathrate.
What animals live in the high pressures on the sea bed?
The kraken
When water becomes a gas?
Water becomes a gas when it reaches the boiling point, which is 100 C at sea level. The boiling point is different at lower air pressures / higher elevations.
What is the opposite of below sea level?
above sea level
