Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
Half the mass of the atmosphere is found below an altitude of about 5.6 kilometers because the air is compressed by the weight of the overlying atmosphere, leading to higher density at lower altitudes. The pressure decreases with altitude due to the decreasing thickness of the air column above.
As seawater temperature decreases, its density increases until it reaches its maximum density at around 4 degrees Celsius. Further cooling below this temperature causes the density to decrease due to the formation of ice, which is less dense than liquid water.
Altitude is the distance above ground-level that an object is, in a vertical direction (that is, directly away from the centre of the Earth). If this is negative then the object is below ground-level, so it is underground.
The Earth's density increases with depth because of the increasing pressure from the layers of material above. As you move deeper into the Earth, the weight of the material above compresses the layers below, causing them to become more compact and increase in density. Additionally, the heavier elements tend to sink towards the center of the Earth, further contributing to the overall increase in density with depth.
Badwater Basin in California is located at an altitude of 282 feet (86 meters) below sea level, making it the lowest point in North America.
It increases by 1 atmosprere every 33 feet.
The atmosphere becomes less dense with altitude. Atmosphere, thin though it is, has weight, and it is the weight of the air above which compresses the air below it, to greater density.
If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
The thermosphere has lower density than the layers below it but higher than the exosphere above it.The density of the Earth's atmosphere decreases nearly exponentially with altitude. At 400 km altitude the density is typically about 6g/m3 . This changes considerably when there is a solar storm.The air density is so low in this layer that most of the thermosphere is what we normally think of as outer space. In fact, the most common definition says that space begins at an altitude of 100 km (62 miles), slightly above the mesopause at the bottom of the thermosphere.
The density of the gases in space is so low that we would not term them "air". As you increase in altitude from Sea Level the density of air gradually decreases right up until you reach space. There is no point where there is a sudden change so that someone can say that air has stopped and space has begun. Quite simply, the upper reaches of the atmosphere have been defined by picking an altitude. Below that altitude is "air"; above it is "space".

This characteristic is called altitude or elevation.
At the Tropic of Capricorn (approximately 23.5 degrees south latitude), Polaris, the North Star, is not visible and is located below the horizon. Polaris can only be seen in the Northern Hemisphere and its altitude above the horizon increases the further north you go.
It is the altitude.
Yes, that is correct. Altitude above sea level, for example, is negative or positive - if you are below sea level, a negative number will be used.
