Over rocky surfaces with no plant cover, the potential evaporation is, then the actual evaporation a) equal to b) much greater than c) less than

The correct option is : B) much greater than    

Explanation:

Potential evaporation is defined as the ability of the atmosphere to carry out the process of evaporation from the surface of the earth.

Actual evaporation is the amount of water actually evaporated from the surface into the atmosphere.

Transpiration is the evaporation of water from the leaves, stems and the flowers of the plants into the atmosphere.

In the absence of plants, transpiration becomes zero and thus, the ability of the atmosphere to carry out the process of evaporation increases.

Therefore, potential evaporation is much greater than the actual evaporation, in the absence of plants.

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
