Sunlight plays a crucial role in the water cycle by providing the energy needed for evaporation. When the sun heats up water in rivers, lakes, and oceans, it turns into water vapor and rises into the atmosphere. Sunlight also helps ...

Water can evaporate on cool days because evaporation depends on the movement of water molecules. Even on cool days, some molecules in the water have enough energy to escape into the air as vapor. The process of evaporation happens as ...

Precipitation is the process where water falls from the clouds to the Earth. It occurs when water vapor in the air cools down and condenses into droplets, forming clouds. When these droplets combine and become heavy, they fall as rain, ...

The water level in a closed container remains constant because the water cannot escape. In a closed container, no water can evaporate or be added from outside. The amount of water stays the same, so the water level does not ...

When water vapor cools, it changes into tiny water droplets, a process called condensation. The cooling causes the water vapor to lose energy, and as it cools, it turns from a gas back into a liquid. This is how clouds, ...

Water vapor can be turned back into liquid water through a process called condensation. When warm water vapor cools down, it loses energy and changes into tiny water droplets. This happens when the water vapor comes into contact with a ...
