Troposphere: The layer of atmosphere closest to the Earth, extending seven to ten miles above the surface, containing most of the clouds and moisture.
Troposphere - The lowest layer of the Earth's atmosphere, ranging from the ground to the base of the stratosphere with a altitude of 10-15 kilometers depending on the latitude. This is where all weather occurs.
Troposphere: Layer of the atmosphere that contains about 95 per cent of the Earth's air and extends about six to 17 km up from the Earth, depending upon latitude and season.
Troposphere - the layer of the atmosphere nearest the earth's surface. The troposphere extends outward about 5 miles at the poles and 10 miles at the equator

troposphere The layer of the atmosphere from the earth's surface up to the tropopause, characterized by decreasing temperature with height (except, perhaps, in thin layers - see inversion, cap), vertical wind motion, ...

Troposphere stems from the Greek word tropos, which means turning or mixing. The troposphere is the lowest layer of the Earth's atmosphere, extending to a height of 8-15 km, depending on latitude.
Troposphere The lower atmosphere, from the earth's surface to approximately 12 km. This portion of the earth's atmosphere contains about 95 percent of the atmospheric gases. The temperature gradually declines through this region.

tropopause The boundary between the troposphere and the stratosphere (about 8 km in polar regions and about 15 km in tropical regions), usually characterized by an abrupt change of lapse rate.
Ozone (O3): Found in two layers of the atmosphere, the stratosphere and the troposphere.
The layer nearest the Earth is the troposphere, which reaches up to an altitude of about 8 km (about 5 miles) in the polar regions and up to 17 km (nearly 11 miles) above the equator. The weather we experience takes place within the troposphere.
Our concern is mainly with layers of air near the ground, called the troposphere. The troposphere has an altitude of about 7 to 9 kilometres in the polar regions and about 16 kilometres in the equatorial regions.
In the troposphere, it is created both naturally and by photochemical reactions involving gases resulting from human activities (photochemical smog). In high concentrations, tropospheric ozone can be harmful to a wide range of living organisms.
Water vapor in the troposphere, unlike the better-known greenhouse gases such as CO2, ...
Troposphere The troposphere is the layer of atmosphere closest to the ground.Tsunami A wave caused by an underwater earthquake or landslide which can rise to great heights and cause catastrophic damage to the coast.
In the troposphere - at ground level - it is created both naturally and by photochemical reactions involving gases resulting from human activities (photochemical smog).
There are two opposed effects: reduced ozone allows more solar radiation to penetrate, thus warming the troposphere. But a colder stratosphere emits less long-wave radiation, tending to cool the troposphere.
Although chemically inert in the lower atmosphere (troposphere), they are taken to very high altitudes where they are broken down into their components by the stronger sunlight (UV) at these altitudes.
The man-made ozone that forms in the troposphere is extremely toxic and corrosive. People who inhale ozone during repeated exposure may permanently damage their lungs or suffer from respiratory infections.
Global Warming: Global warming is an average increase in the temperature of the atmosphere near the Earth's surface and in the troposphere, which can contribute to changes in global climate patterns.
Ozone (O3) - Ozone is a greenhouse gas present in the stratosphere and the troposphere. In the stratosphere, ozone provides a protective layer shielding the earth from harmful ultraviolet radiation.
The gases are mainly nitrogen and oxygen, together with elements of inert gases hydrogen, ozone, radon, and carbon dioxide. There are different layers - the troposphere nearest the earth, then the stratosphere up to 50 kilometres, ...
The result of photochemical reactions of nitric oxide in ambient air; major component of photochemical smog. Product of combustion from transportation and stationary sources and a major contributor to the formation of ozone in the troposphere and to ...
Chemical compounds, such as carbon monoxide, methane, non-methane hydrocarbons, and nitrogen oxides, which in the presence of solar radiation react with other chemical compounds to form ozone, mainly in the troposphere.
