The 27 pages that link to Atmosphere of Earth, each with the reason it gives.

• Hydrostatic equilibriumBroader topic: Its pressure generally decreases with altitude because the air above supports the air below.

• X-ray astronomyCompared with: Its absorption forces most astronomical X-ray observations onto spacecraft or high-altitude platforms.

• EarthBroader topic: Its composition regulates temperature and shields the surface from radiation.

• Planetary atmosphereBroader topic: Earth's atmosphere is a familiar case with a surface, active weather, and abundant liquid water.

• AtmosphereBroader topic: It is the familiar case, with abundant surface liquid water and life-altered composition.

• SpaceflightRelated: Its thinning boundary distinguishes atmospheric flight from spaceflight in practical definitions.

• MoonlightRelated: Atmospheric scattering changes moonlight’s color, contrast, and reach at the ground.

• StratosphereNarrower topic: The stratosphere is one major layer of Earth’s atmosphere.

• ThermosphereNarrower topic: The thermosphere is one of its major layers.

• XenonRelated: Earth’s atmosphere contains only trace xenon, far less than its abundance in some meteorites.

• Early EarthRelated: Its early composition differed sharply from today’s oxygen-rich atmosphere and evolved through degassing and chemical change.

• Riccardo GiacconiCompared with: Atmospheric absorption forced Giacconi's instruments onto rockets and satellites rather than ground-based observatories.

• ArgonRelated: Argon is the atmosphere’s third most abundant gas, after nitrogen and oxygen.

• Atmosphere of MarsCompared with: Earth’s denser, nitrogen-rich atmosphere provides a sharp comparison with Mars’s low-pressure carbon dioxide air.

• Atmosphere of TitanCompared with: Both atmospheres are nitrogen-rich, but Titan’s is colder, denser at the surface, and oxygen-poor.

• OutgassingBroader topic: Volcanic and mantle outgassing contributed gases to the evolving early atmosphere.

• Atmosphere of JupiterCompared with: Its heavier composition and solid surface distinguish its weather system from Jupiter’s deep gas envelope.

• MesosphereNarrower topic: The mesosphere is one layer within this gaseous envelope.

• NeonRelated: Trace neon in the atmosphere is the principal natural source for commercial extraction.

• Volcanic outgassingRelated: Volcanic emissions have contributed gases to the atmosphere over geological time.

• AirplaneNarrower topic: Air density and pressure in the atmosphere shape airplane performance and operating limits.

• Atmosphere of VenusCompared with: Unlike Earth’s atmosphere, Venus’s is overwhelmingly carbon dioxide and far denser at the surface.

• Blue hourNarrower topic: Its gases and particles scatter the sunlight that remains after sunset or before sunrise.

• Kármán lineNarrower topic: The atmosphere has no sharp upper edge, unlike the neat boundary implied by the line.

• Outer spaceCompared with: Its gradual transition into space makes any boundary between atmosphere and space conventional.

• Earth’s shadowRelated: Unlike an airless shadow boundary, Earth’s atmosphere refracts and filters light within the umbra.

• Interplanetary mediumCompared with: Unlike the interplanetary medium, it is dense, mostly neutral, and retained by a planet’s gravity.
