In this way, Earth's atmosphere can be divided (called atmospheric stratification) into five main layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The altitudes of the five layers are as follows: Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) See more 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 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 constant or even increase with altitude in some regions (see the temperature … 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 … See more Earliest atmosphere The first atmosphere consisted of gases in the solar nebula, primarily hydrogen. There were probably simple hydrides such as those now found in the gas giants (Jupiter and Saturn), notably water vapor, methane and 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) varies significantly from around 10 ppm by … See more Pressure and thickness The average atmospheric pressure at sea level is defined by the International Standard Atmosphere as 101325 pascals (760.00 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 WebOur planet is surrounded by an invisible shell of air, called the atmosphere, held in place by the Earth’s gravitational field.
