How Does Rain From and What Is The Water Cycle?

    Let's look at the size of rain and how raindrops fall first. We’ll need the Sun when the Sun shines on water on the Earth's surface, the heat of the Sun warms the water turning it into an invisible gas called water vapour.

    This process the changing of water into a gas is called evaporation because gases are lighter than liquids. Water vapor rises up into the sky and the further you move up and away from the Earth's surface the colder temperature gets, so in the sky the water vapor cools and changes back into tiny water droplets. This change is called condensation, and it is the opposite of evaporation.

     Clouds are made up of tiny water droplets so when condensation occurs in the sky clouds form and grow. When water droplets bump into one another they stick together and grow in size they continue to grow until they are too heavy and fall as rain. They even grows they bump into one another on their journey fromthe cloud to the ground and every single raindrop that reaches the ground is made up of 1 million of the original tiny water droplets.

    Raindrops fall on the ground surface or the Sun can shine on them and the whole process happens again. This is called the water cycle and keeps water moving from the ground to the sky providing the water needed for plants animals and people to survive.
