tro·po·sphere

 (trō′pə-sfîr′, trŏp′ə-)
n.
The lowest region of the atmosphere between the earth's surface and the tropopause, characterized by decreasing temperature with increasing altitude.

tro′po·spher′ic (-sfîr′ĭk, -sfĕr′-) adj.

troposphere

(ˈtrɒpəˌsfɪə)
n
(Physical Geography) the lowest atmospheric layer, about 18 kilometres (11 miles) thick at the equator to about 6 km (4 miles) at the Poles, in which air temperature decreases normally with height at about 6.5°C per km
tropospheric adj

trop•o•sphere

(ˈtrɒp əˌsfɪər, ˈtroʊ pə-)

n.
the lowest layer of the atmosphere, varying in height from 6 to 12 mi. (10 to 20 km), within which nearly all clouds and weather conditions occur.

tro·po·sphere

(trō′pə-sfîr′, trŏp′ə-sfîr′)
The lowest region of the atmosphere, bounded by the Earth's surface and the tropopause and characterized by temperatures that decrease with increasing altitude. Weather and most cloud formations occur in the troposphere.

troposphere

The lower layers of atmosphere, in which the change of temperature with height is relatively large. It is the region where clouds form, convection is active, and mixing is continuous and more or less complete. See also atmosphere.

troposphere

the region of the earth’s atmosphere between the surface of the earth and the stratosphere.

troposphere

The layer of the atmosphere lying nearest the Earth which varies in thickness from 11 mi (18km) at the equator to 6.2 mi (10km) at the poles.
