- The term 'aerosphere' [air-oh-sfeer] refers to the part of the earth's atmosphere that contains air and water vapor. It is where weather occurs and is important for sustaining life on Earth.

Mar 24, 2018 · The aerosphere is a fluid and rapidly evolving medium, which provides habitat for an abundance of organisms. The evolution of life on earth is replete with examples of key adaptations that enable all forms of life to use the atmosphere to move in ways that are simply impossible otherwise.

The troposphere is the lowest layer in the atmosphere. It extends upward to about 10 km above sea level starting from ground level. The lowest part of the troposphere is called the boundary layer and the topmost layer is called the tropopause. The troposphere contains 75% of all air in the atmosphere. Most clouds appear in this layer because 99% of...
Above the troposphere lies the stratosphere which extends from the top of the troposphere to about 50 km (31 miles) above the ground. The ozone layer lies within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun and convert it into heat. Because of this, unlike the troposphere, the stratosphere g...
Above the stratosphere is the mesosphere and it extends to a height of about 85 km (53 miles) from the ground. Here, the temperature grows colder as you rise up through the mesosphere. The coldest parts of our atmosphere are located in this layer and can reach –90°C.
Thermosphere lies above the mesosphere and this is a region where the temperature increases as you go higher up. The temperature increase is caused due to the absorption of energetic ultraviolet and X-ray radiation from the sun. However, the air in this layer is so thin that it would feel freezing cold to us! Satellites orbit Earth within the therm...
Exosphere is the final frontier of the Earth’s gaseous envelope. The air in the exosphere is constantly but gradually leaking out of the Earth’s atmosphere into outer space. There is no clear cut upper boundary where the exosphere finally fades away into space.
The ionosphere isn’t a distinct layer unlike other layers in the atmosphere. The ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules.
May 21, 2008 · Ecologists who study species that use the aerosphere face three important challenges: (1) to discover how best to detect the presence, taxonomic identity, diversity, and activity of organisms that use this space, (2) to identify ways to quantify relevant environmental variables at different temporal and spatial scales, and (3) to determine how ...

Air is the invisible mixture of gases that surrounds Earth. Air contains important substances, such as oxygen and nitrogen, that most species need to survive. Grades. 5 - 8. article. Parts of the Atmosphere. Chemistry, Earth Science, Astronomy, Meteorology, Geography, Physical Geography.
Definition. The atmosphere is a layer of gases surrounding a planet, held in place by gravity. It plays a crucial role in supporting life, regulating temperature, and protecting the surface from harmful solar radiation.
Atmosphere: Definition. The atmosphere can be described as a layer of gases surrounding the earth. These gasses are oxygen, carbon dioxide, nitrogen, argon and other gases. Other component of atmosphere which is of great importance is the water vapor.
