Atmosphere

Presentations | English

"The atmosphere is the mass of gases that are attracted to a cosmic object of sufficient mass around it. None of the other known planets has a similar atmosphere as Earth. The atmosphere acts as a shield against the ultraviolet rays of the sun. It is the presence of the atmosphere that protects the earth from overheating. The region at the bottom of the atmosphere that is chemically uniform is called the homosphere, but the surface is not uniform. This is called the heterosphere. Atmospheric pressure is the force felt perpendicular to a surface located in the air. Atmospheric pressure is determined by the gravitational force of the object and the weight of the gas column above the measured area. It decreases with increasing height. Pascal is the unit currently used to measure pressure. A pascal is a pressure exerted by a Newtonian force on a surface area of ​​one square meter. Atmospheric pressure at the Earth's surface is about 100 ps. The formerly used unit, the bar, and the one-thousandth, the millibar, are still widely used."
