Interpretation: To determine why water bodies with large surface areas such as lakes and oceans do not evaporate easily.
Concept Introduction: Evaporation is considered a process in which water will turn into liquid. The conversion of liquid to vapor is considered evaporation. Evaporation is a natural phenomenon that absorbs heat from the surrounding liquid. This phenomenon takes place at the surface of the liquid.

Answer to Problem 31A
The water in water bodies with large surfaces is in more quantity, therefore, it is difficult for evaporation to take place as it is a slow process.
Explanation of Solution
When water bodies with large surfaces are considered, there is a huge amount of water. Evaporation is a slow process and takes place at the surface of the water. Since there is a huge amount of water in the lakes and oceans and evaporation is a slow process, it is difficult for evaporation to take place rapidly.
Evaporation of liquid decreases with an increase in the humidity of the atmosphere. Similarly, when the temperature of the atmosphere increase, evaporation will also increase. Since evaporation is a slow process, it does not occur rapidly.
