Due to evaporation of water from the surface of the sea! The most dense gases in the atmosphere are naturally at the bottom. Also, with so much air being directly above all the way up about 100 Km being pulled down onto the lower air, the atmosphere is denser.
The layer of the atmosphere at sea level is known as the troposphere. This is where most weather phenomena occur and it extends from the Earth's surface up to an average height of about 8 to 15 kilometers.
No, Scotland is not under sea level. The country's elevation varies, with some low-lying areas near sea level, but the majority of Scotland's landmass is above sea level.
In some places Yuma is at sea level.
The tropopause is the boundary between the troposphere and the stratosphere. Its height asl varies with latitude (highest near the equator). 12-15 km approx.
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
Denser, heavier air.
A pressure measurement, in comparison to atmospheric pressure on Earth, at sea level, near sea level, at standard temperature, usually expressing an absolute pressure (but does not have to be). 1 atmosphere absolute = 1.01325 bar absolute 1 atmosphere absolute = 101,325 pascal absolute 1 atmosphere absolute = 14.69595 psi absolute
probally near sea level
The air we breathe near sea level is approximately 78% nitrogen, 21% oxygen, and 1% other. The exact composition changes at different levels in the atmosphere.
At sea level
1 atmosphere is equivalent to approximately 10 meters above sea level.
The average pressure exerted by the atmosphere at sea level is about 101.3 kilopascals, or 14.7 pounds per square inch.
The layer of the atmosphere at sea level is known as the troposphere. This is where most weather phenomena occur and it extends from the Earth's surface up to an average height of about 8 to 15 kilometers.
Closest to the surface of the earth at Sea level or any portion of land that lies below Sea level.
The atmosphere is more dense at the ocean than at the top of a mountain. As altitude increases, atmospheric pressure and density decrease, meaning that the air is thinner at higher elevations. Therefore, at sea level, such as at the ocean's surface, the atmosphere is denser compared to the air found at the summit of a mountain.
1 atmosphere, at sea level.
No. It may be denser than the ocean, but nowhere near dense enough.
