Invented in the 17th century, this instrument uses mercury or aneroid cells to detect subtle changes in weight. At the summit of Mount Everest, for instance, the pressure is less than a third of what it is at sea level, making survival impossible without supplemental oxygen.
Weight of Our World Atmosphere: How It Presses Down on Us
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. 325 kilopascals) at sea level.
Without this protective cushion, the world would be a frozen, airless void, similar to the conditions found on the Moon. Conversely, low-pressure systems are characterized by rising air, which cools and condenses to form clouds and precipitation.
Weight of Our World Atmosphere: How Much Pressure It Exerts
Measuring the Invisible To quantify this invisible force, scientists rely on the barometer. High and Low Pressure Systems Meteorologists track these variations through isobars on weather maps, which connect points of equal pressure.

Looking at Earth's atmosphere pressure from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on Earth's atmosphere pressure can make the topic easier to follow by connecting earlier points with a few simple takeaways.
