Answer:
E. the troposphere has a homogenous composition of all gasses and vapors including water.
Step-by-step explanation:
- The troposphere being a region of mixing is the homogenous composition of gases and water vapor that can be found in abundance in this layer above the surface of the earth.
- It is the stage for 99% of all the weather phenomenon and is well defined from the equator to poles. It is less dense near the equator and denser near the poles.
- About 75 % of the atmosphere is found below this layer above which lies the tropopause where the mixing stops and no changes in temperature at this layer. The layer extends from 0 to 20 kilometers in height.
- Apart from this dust particles are also found in this layer of the atmosphere.
