    water does evaporates, goes into the atmosphere and comes down again as rain somewhere else. basically no water leaves the planet because the gravitational field is strong enough to retain practically all of it, even over billions of years.

    typically, due to trade winds, winds generally blow towards the west in mid-latitudes. so if water evaporates in new york, it probably rains down over the midwest. if it evaporates over the midwest, it comes down in the great desert west of the midwest. in these cases, water isn’t lost as it falls down again over soil.
