The prefix tropo-denoting turning, a change, is derived from the Greek word tropos, a turning. The troposphere is the lowest level of atmosphere in which the temperature fall â¦ s as height increases.ropo-comes from the Greek tropos which means turning.. Meso-comes from the Greek mesos which means middle.. Thermo-comes from the Greek thermos which means hot.. Exo- â¦ comes from the Greek exÅ which means outside..
The troposphere is the lowest part of the atmosphere of the Earth. It is shallower near the polar regions and is denser in the tropics. Observable day-to-day weather phenomenoâ¦n occur here. The temperature of the troposphere decreases with increase in height and hence water vapour content decreases with height. An imaginary line at the boundary of the troposphere and the stratosphere is known as tropopause. The troposphere constitutes 80% of the total mass of the atmosphere and almost all of the water vapour and atmospheric particulate matter are concentrated in this layer.
