Changes in pressure, such as those experienced by mountaineers or deep-sea divers, can lead to serious medical conditions like altitude sickness or decompression sickness. It drives wind, dictates climate zones, and ensures that liquids like water remain in a fluid state across the planet's surface.

Because of this mass, the atmosphere behaves like a dense fluid, exerting a force of approximately 101,325 Pascals (or 101. Invented in the 17th century, this instrument uses mercury or aneroid cells to detect subtle changes in weight.
The air is composed of nitrogen, oxygen, argon, and trace amounts of other gases, all of which have mass. High and Low Pressure Systems Meteorologists track these variations through isobars on weather maps, which connect points of equal pressure.

Cold air is denser and sinks, creating areas of high pressure, while warm air rises, leading to zones of low pressure. Without this protective cushion, the world would be a frozen, airless void, similar to the conditions found on the Moon.
