The rate of evaporation depends on several factors, including the temperature of the water, the humidity of the air, and the wind speed. Evaporation is more rapid when the water temperature is higher, humidity is lower, and the wind speed is higher.
In the case of ocean, rivers, and lakes, evaporation occurs constantly. However, the rate of evaporation is usually balanced by the rate of precipitation (rain, snow, or sleet), so the levels of these bodies of water remain relatively constant. However, in some cases, such as during a drought, the rate of evaporation may exceed the rate of precipitation, leading to a decline in the water levels of these bodies of water.
Overall, ocean, river, and lake can turn into gas through the process of evaporation, but the rate of evaporation is usually balanced by the rate of precipitation, maintaining the levels of these bodies of water.
