An atmosphere is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth’s gravitational attraction. Argon, oxygen and nitrogen from the three main constituents of the atmosphere. Definition.
An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam', and σφαῖρα (sphaîra) 'sphere') is a layer of gasses that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
Jun 3, 2024 · Atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice-covered surface of a planet outward into space. The density of the atmosphere decreases outward, because the planet’s gravitational attraction, which pulls the gases and aerosols inward, is greatest close to the surface.
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.
Oct 19, 2023 · Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
May 13, 2024 · “The Earth’s atmosphere allows life to exist. . . like a protective bubble that surrounds the planet,” stated Ueyama. Although we cannot directly see the atmosphere, it provides the air we breathe and protects us from harmful ultraviolet (UV) rays.
Earth is surrounded by a mixture of gases called the atmosphere. The composition of the atmosphere is 78 % nitrogen and 21 % oxygen, with the remaining 1 % consisting of water vapor, argon, carbon dioxide, and small amounts of other gases.
Dec 11, 2019 · Earth’s atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. A jacket for the planet Earth is a great planet to live on because it has a wonderful atmosphere around it.
An atmosphere is made of the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
Part One sidebar: Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
