Atmosphere The current composition of the Earth's atmosphere is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms. The term stellar atmosphere describes the outer region of a star and typically includes the portion above the opaque photosphere.

Atmosphere An atmosphere is more likely to be retained if the gravity is high and the atmosphere's temperature is low. The atmosphere of Earth is mostly composed of nitrogen. It also contains oxygen used by most organisms for respiration and carbon dioxide used by plants, algae and cyanobacteria for photosynthesis.It protects living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays.ars's thin atmosphere. The layers of Earth's atmosphere. An atmosphere (New Latin atmosphaera, 17th century, from Greek ἀτμός [ atmos ] vapor and σφαῖρα [ sphaira ] sphere) is a layer of gases surrounding a planet or other material body of sufficient mass that is held in place by the gravity of the body.

Earth's Atmosphere: Composition, Climate & Weather Earth is the only planet in the solar system with an atmosphere that can sustain life. The blanket of gases not only contains the air that we breathe but also protects us from the blasts of heat and radiation emanating from the sun. It warms the planet by day and cools it at night.

- Air is a mixture of gases and aerosols that composes 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.

Atmosphere Mars's thin atmosphere. The layers of Earth's atmosphere. An atmosphere (from Greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'sphere') is a layer of gases surrounding a planet or other material body, that is held in place by the gravity of that body.

- The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space. 1) The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer.

Atmosphere of Earth Earth's atmosphere is the layer of gases around the Earth. The atmosphere is held in place by Earth's gravity. It is made up of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (~ 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun.

Layers of Earth's Atmosphere The Earth's Atmosphere. The atmosphere surrounds Earth and protects us by blocking out dangerous rays from the sun. The atmosphere is a mixture of gases that becomes thinner until it gradually reaches space. It is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%).he troposphere is the lowest layer of the Earth's atmosphere. The air is very well mixed and the temperature decreases with altitude. Air in the troposphere is heated from the ground up. The surface of the Earth absorbs energy and heats up faster than the air does.

Introduction to the Atmosphere The general concepts found in this section are: 1  The earth's atmosphere is a very thin layer wrapped around a very large planet. 2  Two gases make up the bulk of the earth's atmosphere: nitrogen (), which comprises 78% of the atmosphere, and oxygen (), which accounts for 21%. Various trace gases make up the remainder. Based on temperature, the atmosphere is divided into four layers: the troposphere, stratosphere, mesosphere, and thermosphere.

Earth's Atmosphere: Composition, Climate & Weather The troposphere is the layer closest to Earth's surface. It is 4 to 12 miles (7 to 20 km) thick and contains half of Earth's atmosphere. Air is warmer near the ground and gets colder higher up. Nearly all of the water vapor and dust in the atmosphere are in this layer and that is why clouds are found here. The stratosphere is the second layer. It starts above the troposphere and ends about 31 miles (50 km) above ground.

- The atmosphere is made up of several layers: the troposphere, stratosphere, mesosphere, ionosphere, and exosphere. Closest to Earth is the troposphere. Most of the clouds you see in the sky are found in the troposphere, and this is the layer of the atmosphere we associate with weather.Extending up to 10 miles above Earth's surface, the troposphere contains a variety of gases: water vapor, carbon dioxide, methane, nitrous oxide, and others.his is the outermost layer of the atmosphere, the transition zone into space. The greenhouse effect. The gases in the atmosphere that help retain heat are called greenhouse gases. These gases, primarily carbon dioxide (CO2), absorb heat instead of allowing it to escape into space.

Composition of Earth's Dry Atmosphere (as of 2009) The Earth's Atmosphere. Source: NASA. The majority of the Earth's atmosphere is composed of a mixture of only a few gases-nitrogen, oxygen, and argon; combined these three gases comprise more than 99.5% of all the gas molecules in the atmosphere.

- The structure of the atmosphere dictates the way the atmosphere behaves and controls how weather develops near the surface of the earth. I should already be familiar with: Humidity, Temperature, Pressure, Density. The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere.

To the Edge of Space Most familiar of these to us, because we live in it, is the troposphere. Most massive (about 80% of the atmosphere), warmest and most turbulent of the atmosphere’s layers, the troposphere starts at ground level and extends about a dozen kilometres on average above our head.

oce ch6 Describe the physical properties of the atmosphere, including its composition, temperature, density, water vapor content, pressure, and movement. The atmosphere is composed almost entirely of nitrogen and oxygen. The lowest portion of the atmosphere is the troposphere, which is the area where temperature gets cooler with altitude. Warm air is less dense and so it rises. Cold air is denser, so it sinks.
