Why is air pressure greatest at sea level?

Answer 1

Air is like water in that the deeper you go down the higher the pressure. Think of a circle on the ground and imagine a column of Air above it. As you increase in height the pressure decreases. For water, the further a diver goes down, the higher the pressure becomes.

Answer 2

Air Pressure has to do with the Weight of Air in the Atmosphere. Imagine that the Atmosphere is like the Ocean. The 'Deeper' you go the greater the Pressure because there is more Fluid Volume above you pushing down. In the Atmosphere the LOWER the Altitude the greater the Pressure.

SEA LEVEL is an established STANDARD for Pressure measurements. But there are many areas on land below sea level and those areas have an even greater pressure than at Sea Level.

It is not.

Answer 3

Air pressure is greater because as you descend, you have more air (above you) pushing down on you. But this was not exactly a fair question, as the greatest air pressure occurs naturally at the shores of the Dead Sea.

It's just like when you go down in water; the water pressure increases. The weight of the atmosphere is pressing on the water surface, and the weight of the air and water above you is pressing on your skin.

When you go down into the atmosphere, just the weight of the air increases. If you go to the shore of the Dead Sea, which is dry land farthest below sea level, the air pressure is the greatest.

However, there are deep mines we can go into and measure even greater air pressures...

Answer 4

Air pressure decreases with increasing altitude because there is more air pressing down on you at lower altitudes. This is because the weight of the air above exerts more pressure on the air below at sea level compared to higher altitudes.
