Question

Evaporation and transpiration are the only two processes that return water to the atmosphere. Since oceans cover approximately 70% of the Earth's surface, explain why evaporation places more water into the atmosphere than transpiration. (Answer must be at least one sentence long)

Answer 1

Answer:

See the answer below

Explanation:

Evaporation places more water into the atmosphere than transpiration because the water in the oceans has a larger surface area than the plants put together. Also, there is no barrier between the surface of the various oceans and the atmosphere, meaning that evaporation can occur directly without any hindrance - other things being equal. However, in plants, transpiration is controlled by the guard cells of the stomata. The opening/closing of the stomata is regulated by homeostatic processes.
