Layers of the atmosphere

Earth and Titan are known to have liquids at their surface and terrain on the planet suggests that Mars had liquid on its surface in the past. This layer is mainly composed of extremely low densities of hydrogen, helium and several heavier molecules including nitrogen, oxygen and carbon dioxide closer to the exobase.

Atmosphere of Earth

However, atmospheres are not uniform Layers of the atmosphere temperature, so estimation of the atmospheric pressure at any particular altitude is more complex. The temperature of the thermosphere gradually increases with height. The mesosphere is also the layer where most meteors burn up upon atmospheric entrance.

The Layered Atmosphere Stand outside and look up. Atmospheric pressure Atmospheric pressure at a particular location is the force per unit area perpendicular to a surface determined by the weight of the vertical column of atmosphere above that location.

The height of the thermopause varies considerably due to changes in solar activity. Average temperature profile for the lower layers of the atmosphere. This outer region surrounding the earth, where charged particles spiral along the magnetic field lines, is called the magnetosphere.

Unsourced material may be challenged and removed. Thermosphere Between about 53 miles 85 km and miles km lies the thermosphere. However, polar stratospheric or nacreous clouds are occasionally seen in the lower part of this layer of the atmosphere where the air is coldest.

So air higher up is cooler than air lower down.


By comparison, the summit of Mt. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! It has basically all the weather-associated cloud genus types generated by active wind circulation, although very tall cumulonimbus thunder clouds can penetrate the tropopause from below and rise into the lower part of the stratosphere.

The atmospheres of the planets Venus and Mars are primarily composed of carbon dioxidewith small quantities of nitrogenargonoxygen and traces of other gases. This increase in temperature with height means warmer air is located above cooler air. The five basic layers of the atmosphere Exosphere This is the outermost layer of the atmosphere.

Common examples of these are CO2 and H2O. These planets have hydrogen—helium atmospheres, with trace amounts of more complex compounds.

The exosphere is located too far above Earth for any meteorological phenomena to be possible. Now humans have stopped making most of the harmful CFCs we expect the ozone hole will eventually recover over the 21st century, but this is a slow process.Layers of the Earth's Atmosphere 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.

Our atmosphere is the layers of gases surrounding the earth. There are five layers, called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. An atmosphere (from Greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.

An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low.

Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical composition, movement, and density occur. The five basic layers of the atmosphere Exosphere. This is the outermost layer of the atmosphere.

It extends from the. The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.

A further region at about km above the Earth's surface is called the exosphere. Aug 07,  · Earth's Atmospheric Layers. Diagram of the layers within Earth's atmosphere. Troposphere The troposphere starts at the Earth's surface and extends 8 to kilometers high (5 to 9 miles).

This part of the atmosphere is the most dense. Almost all weather is in this region.
