The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention (greenhouse … See more The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere by mass. The concentration of water vapor (a greenhouse gas) … See more Pressure and thickness The average atmospheric pressure at sea level is defined by the International Standard Atmosphere as 101325 pascals (760.00 Torr; 14.6959 psi; 760.00 mmHg). This is sometimes referred to as a unit of standard atmospheres (atm) See more On October 19, 2015, NASA started a website containing daily images of the full sunlit side of Earth at See more In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile with altitude, and may remain relatively … See more Solar radiation (or sunlight) is the energy Earth receives from the Sun. Earth also emits radiation back into space, but at longer wavelengths that humans cannot see. Part of the incoming and emitted radiation is absorbed or reflected by the atmosphere. In May … See more Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is … See more Earliest atmosphere The first atmosphere consisted of gases in the solar nebula, primarily hydrogen. There were probably … See more WebThe Earth, with a thinner atmosphere, has a mild 33 K warming. However, this warming of the Earth above the freezing point of water (273 K) has profound consequences, because life, as we know it, would not be possible on a planet where the water is permanently frozen—the snowball Earth instead of the “blue marble” shown in the figure.

At sea level this air produces a pressure on our bodies of 1.0 atm., 1.01 10 5 Pa, or 14.7 PSI. The area on the face of an average adult's hand is about 0.0116 m 2 or 18.0 square inches so there is about 1200 N (270 pounds) of force bearing down on an average adult human hand. knitting store downtown minneapolis
