Detailed explanation-1: -In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.
Detailed explanation-2: -When water at the ocean’s surface is heated by the Sun it gains energy. With enough energy, the molecules of liquid water change into water vapor and move into the air. This process is called evaporation.
Detailed explanation-3: -Seawater absorbs heat from the sun rays. This leads to conversion of water into its vapour. Thus, heat from the Sun causes evaporation of seawater.
Detailed explanation-4: -When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation. Water vapor (steam) mixes with the air and seems to disappear.
