1. troposphere
   The lower regions of a planetary atmosphere where convection keeps the gas mixed and maintains a steady increase of temperature with depth. Most clouds are in the troposphere.

2. troposphere
   The inner layer of the atmosphere below about 15 km, within which there is normally a steady decrease of temperature with increasing altitude. Nearly all clouds form and weather conditions manifest themselves within this region, and its thermal structure is caused primarily by the heating of the Ear...

4. Troposphere
   The lowest part of the atmosphere, from the ground or ocean surface to about 10-15 km up. Noteworthy for containing the vast majority of atmospheric moisture, and the location of nearly all weather phenomena. Above is the stratosphere.

7. Troposphere
   The lowest layer of the Earth's atmosphere, lying at an average height of up to 11km (6.5 miles). Above the troposphere lies the stratosphere, above that the ionosphere, above that the exosphere. In the troposphere the temperature drops steadily except for localised layers of temperture inversion.

8. Troposphere
   The region of the atmosphere closest to the Earth, extending from the surface up to about 10 km in altitude. Almost all weather takes place in the troposphere.

10. troposphere
    Troposphere is the lowest part of the earth's atmosphere, extending to 110 km to 15 km above the surface. It is characterized by a decrease in temperature with increasing altitude. The exact height varies with latitude and season.
