Detailed explanation-1: -All unprotected plant and animal life on the Earth’s surface would die. We can’t survive long in a vacuum, which is what we’d have if the atmosphere suddenly vanished. It would be much like being “spaced’ or shot out of an airlock, except the initial temperature would be higher.
Detailed explanation-2: -Pressure is greatest at sea level and decreases with height. Air is heaviest at sea level because the air molecules are compressed by the weight of the air above them. Air becomes lighter farther away from Earth’s surface as the air molecules become separated by more space.
Detailed explanation-3: -"No human can survive this-death is likely in less than two minutes, ‘’ Lehnhardt said. According to NASA’s bioastronautics data book (opens in new tab), the vacuum of space would also pull air out of your lungs, causing you to suffocate within minutes.
Detailed explanation-4: -In the International Space Station, the density of the air is maintained so that it is similar to the density at the earth’s surface. Therefore, the air pressure is the same in the space station as the earth’s surface (14.7 pounds per square inch).
