Why does evaporation cause water vapor to be enriched in light isotopes in comparison to liquid water? а. light isotopes move faster than heavy isotopes and thus are more readily condensed b. heavy isotopes move faster than light isotopes and thus are more readily condensed с. light isotopes move slower than heavy isotopes and thus are more readily evaporated d. light isotopes move faster than heavy isotopes and thus are more readily evaporated

The correct option is: d. light isotopes move faster than heavy isotopes and thus are more readily evaporated

Explanation:

Evaporation is the process by which water present in liquid state changes into water vapor.

Since, oxygen has two isotopes: ¹⁶O (light isotope) and ¹⁸O (heavy isotope). Therefore, water molecule that consists of ¹⁶O is known as light water (H₂¹⁶O). Whereas, water molecule that consists of ¹⁸O is known as heavy water(H₂¹⁸O).

Since evaporation of heavier water molecules (H₂¹⁸O) is difficult than evaporation of light water molecules (H₂¹⁶O).

Therefore, the water vapor formed by evaporation is rich in light water (H₂¹⁶O).

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
