Answer:
Because the volume of water is higher in oceans than atmosphere
Step-by-step explanation:
Critically looking at water cycle, we could infer that water can exist for a few days in the atmosphere because it also resides on land as well.
The atmosphere is basically a way for the ocean water to run back on land and run off right back into the oceans. It won't come back right away depending squarely on where it goes, but there is a lifetime out of the ocean that balances these times out.
The contributing factor factor to this difference is mainly the volume of water in ocean is higher and evaporation occurs slowly.
