Because the weight is pressing on your entire body, from all directions at once, it doesn't press you toward the Earth. It's the same reason the weight of the water over them doesn't crush fish.
Most organisms are able to take oxygen from the atmosphere through respiration. Plants are able to take in carbon dioxide from the atmosphere during photosynthesis.
Gravity
the sky would be black because if there was no atmosphere then light would be able to get in easlily. you would be able to see stars during broad daylight.
They might not be able to because of their weight
Basically according to the planets mass and whether it has an atmosphere. You weigh less on the Moon and Mars but much heavier if you were able to walk on the surface of Jupiter because it is so massive. Venus is about the same size as the Earth but it has a very dense atmosphere which would squash you flat.
A meteorologist needs to understand the atmosphere and how it works in order to be able to forecast weather.
imagine, what may happen if a stone to weigh 5 billion billion kilograms fall down on earth? The one who holds that atmosphere is Allah as He exploited the rules by his unlimited power, for example if the density of the atmosphere is less than it is ,so it may evaporates and run away in the space and if gravity is less than it is the earth may not be able to hold the atmosphere. Hence Allah almighty selected the right size and weight for earth to keep the atmosphere tenacious
Neon is an element you extract from the atmosphere.
the stratosphere
How the foot is able to support the weight of the body is all dependant on geometry. The arch of the foot supports the most weight. It is angled in such a weigh that the weight is distributed through the legs.
Earth was able to retain an atmosphere due to its gravity, which is strong enough to prevent the gases in the atmosphere from escaping into space. The presence of a magnetic field also helps in protecting the atmosphere from being stripped away by solar winds. Additionally, the continuous process of outgassing from volcanic activity has contributed to replenishing the atmosphere over time.
