The atmosphere grows thinner less dense and lower in pressure as one moves upward from Earth's surface. It gradually gives way to the vacuum of outer space. There is no precise "top" of the atmosphere. Air becomes so thin at altitudes between and km miles up that for many purposes that range of heights can be considered the boundary between the atmosphere and space.
There are several different regions or layers in Earth's atmosphere. Each has characteristic temperatures, pressures, and phenomena. We live in the troposphere , the lowest layer, where most clouds are found and almost all weather occurs. Text on this page is printable and can be used according to our Terms of Service.

The atmosphere protects life on earth by shielding it from incoming ultraviolet UV radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world. Teach your students about the Earth's atmosphere with the resources in this collection. We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet.
Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.

Key Points Atmospheric stratification describes the structure of the atmosphere, dividing it into distinct layers, each with specific characteristics such as temperature or composition. Dry air contains roughly by volume The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and warming the surface through heat retention the greenhouse effect.
In general, air pressure and density decrease with altitude in the atmosphere. Show Sources Boundless vets and curates high-quality, openly licensed content from around the Internet. Licenses and Attributions.
