Question

Which is true?

Answer 1

Answer:

E. the troposphere has a homogenous composition of all gasses and  vapors including water.

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.
