The troposphere is the lowest and thickest layer of the atmosphere. In contact with Earth's surface, the troposphere is heated by solar illumination and conduction. The tropopause is the boundary layer between the troposphere and the...

From the Greek word tropos, meaning turning, troposphere is the zone of moisture-laden storms between the surface and the stratosphere above. Because ice crystals must form before precipitation can begin, the troposphere rises to 10–12 mi...

That layer of the atmosphere closest to the earth and lying immediately below the STRATOSPHERE. It is characterised by a decrease in temperature of around 6.5°C per kilometre increase in height rather than by definite depth, being around 18 km...

The lower level of the atmosphere, extending to about 8 km at the poles and 16 km at the...

The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 75% of the atmosphere's mass and almost all of its water vapor and aerosols. The average depth of the troposphere is about 11 km in the middle latitudes. It is deeper...
