the ocean because of the fact that in an aquarium if its indoors the sun wont hit it at al even if its outdoors the ocean is way to huge and its because of the ocean that we have clouds. Pond, same thing the ocean beats it
The answer is Ocean. Oceans are larger than ponds and or an aquarium. Hence they possess wider exposed surface with more number of free surface molecules.Greater the number of surface molecules, greater number of molecules may escape from the surface easily..and hence greater will be the rate of evaporation. The rate of evaporation depends even on the external climatic conditions such as Temperature, Wind, Pressure etc. Higher the temperature. higher will be the rate of evaporation.
