Planetary atmospheres are layers of gas that surround planets and some smaller bodies in our solar system. They can extend thousands of kilometers into space. Atmospheres are part of the complex processes that make each planet unique. They reflect the history and evolution of that particular place. For example, Earth's atmosphere is life-supporting, but it was also shaped by life. Here are some examples of planetary atmospheres: Earth: Life-supporting, composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases Venus: Thick and blanketing,...

Each of the outer planets is composed of hydrogen and helium. A standard atmosphere is a unit of pressure that is equal to the average atmospheric pressure at sea level. It is also known as an atmosphere or standard sea-level pressure. The standard atmosphere is defined as 101325 Pa and is sometimes used as a reference pressure or standard pressure. It is equivalent to 101,325 pascals and corresponds to the pressure exerted by a vertical column of mercury that is 760 mm (29.9213 inches) high. The Earth's atmosphere has five major layers: Troposphere: The lowest layer of the Earth's atmosphere, extending from the Earth's surface to an average height of about 12 km. Stratosphere: Extends from the top of the troposphere to the bottom of the mesosphere, and contains the ozone layer. Mesosphere: One of the major layers of the Earth's atmosphere. Thermosphere: Located above the mesosphere, the temperature in the thermosphere generally increases with altitude. Exosphere: One of the major layers of the Earth's atmosphere. The U.S. Standard Atmosphere is defined as a temperature of 288.15 K (15 degrees Celsius, 59 degrees Fahrenheit) at a sea level 0 kilometer geopotential height and pressure of 1 atm. Show less
