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.
<span>ore
An ore is a type of mineral or rock which has a high enough concentration of a desirable element such that it's economical to extract that desired element. This means that the actual concentration of metal in an ore varies quite dramatically depending upon the metal. For instance, Bauxite, which is the ore for aluminum contains approximately 15% to 25% aluminum. But for gold, it's not uncommon to profitably extract 1 ounce of gold from several tons of rock.</span>
