Why are oceans important for evaporation?

Correct answer: They are a huge source of water

Correct answer: D. Oceans cover a very large part of Earth’s surface and contain an enormous quantity of water. Solar energy heats their surface, and some of this water changes into water vapour by evaporation. Winds can then transport the vapour, and it may later condense and contribute to clouds and precipitation. A is incorrect because oceans contain salts but are not important for evaporation only because of salt. B is incorrect because oceans do not simply stop wind; air moves over them and often carries moisture away. C is incorrect because mountain formation is not the reason oceans supply vapour. D is correct because the availability of a large water surface provides the major source of atmospheric moisture. This does not mean land water is unimportant; lakes, rivers, soil, and plants also contribute. Memory cue: oceans are the water cycle’s largest moisture reservoir.
