Atmosphere Homework Describe the composition of the air Air is a mixture of gases and aerosols that compose the atmosphere surrounding Earth. The primary gases of air include nitrogen (78%) and oxygen (21%). Trace gases and aerosols make up the remaining 1% of air. The trace gases include the noble gases argon‚ neon‚ helium‚ krypton and xenon‚ hydrogen and the greenhouse gases. The aerosols are solid or liquid particles having diameters in the region of 0.001 to 10 microns‚ and include dust

Composition of the Atmosphere The Earth is surrounded by air—a mixture of various gases that reaches up to a height of many kilometers. This envelope of air makes up our atmosphere. It is held in place by the Earth’s gravity. Almost all the atmosphere (97 percent) lies within 30 km (19 mi) of the Earth’s surface. The upper limit of the atmosphere is at a height of approximately 10‚000 km (about 6000 mi) above the Earth’s surface—a distance that is nearly as large as Earth’s diameter. The proportion

its small gravity)‚ it has no substantial atmosphere. Its extremely thin atmosphere mostly consists of a small amount of helium and traces of sodium‚ potassium‚ and oxygen. These gases derive from the solar wind‚ radioactive decay‚ meteor impacts‚ and breakdown of Mercury’s crust. Mercury’s atmosphere is not stable and is constantly being refreshed because of its atoms escaping into space as a result of the planet’s heat. The earths atmosphere compared to mercury is much MUCH better in terms of protection
