The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
There are five main layers that make up the atmosphere, differentiated by factors such as temperature, chemical composition, and air density. An illustration of the five different layers of Earth’s atmosphere. NASA GSFC/Mary Pat Hrybyk-Keith. 1. Troposphere. The troposphere is the lowermost atmospheric layer.
What is Earth's atmosphere made of? Earth's atmosphere is made of mainly nitrogen (~78%) and oxygen (21%), with trace amounts of other gases such as argon, water vapor, carbon...
Earth's atmosphere profile. The atmosphere of Earth is composed of layers with different properties, such as specific gaseous composition, temperature, and pressure. The troposphere is the lowest layer of the atmosphere. This extends from the planetary surface to the bottom of the stratosphere.
Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Earth’s atmosphere is bounded at the bottom by water and land—that is, by the surface of Earth. Heating of this surface is accomplished by three physical processes— radiation, conduction, and convection —and the temperature at the interface of the atmosphere and surface is a result of this heating.
The atmosphere is a mixture of gases that surrounds the Earth. It helps make life possible by providing us with air to breathe, shielding us from harmful ultraviolet (UV) radiation coming from the Sun, trapping heat to warm the planet, and preventing extreme temperature differences between day and night.
Earth is surrounded by a relatively thin atmosphere (commonly called air) consisting of a mixture of gases, primarily molecular nitrogen (78 percent) and molecular oxygen (21 percent).
Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, 0.9% argon, and 0.1% other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up that remaining 0.1%.
