The water cycle is a process that goes between land sea and atmosphere. The water cycle changes state in the process into gas, liquid and solid. The steps in the water cycle are evaporation, condensation, precipitation and runoff/groundwater.
One very important part of the water cycle is evaporation. Evaporation is when the sun draws up water to the sky and then turns into a gas and as we know a cloud. The water cycle is an invisible process so when the sun draws up water you can't see it. On hot days more water gets evapt because the hotter the sun the more water gets draw up to the sky and turned into a gas. When warm air with lots of water vapour in it moves into a colder place it causes the water vapour to turn into water which we know as rain. The steps in the water cycle are evaporation, condensation, precipitation and runoff/groundwater but the all need each other.
Condensation is when the water vapour is stuck outside in the cold and can't get drawn up to the sky so it tries to get inside where it is warm and that is condensation we see on our windows. And precipitation is when it rains, when the evaporation water/gas gets too full and starts falling and when it gets closer to the ground it turns into water and when it's higher up it might turn into snow or ice, because it's colder up. After condensation/precipitation is runoff/groundwater.
Runoff/groundwater is nothing more than water running off the land surface. Some water soaks into the ground but most goes over the land. Runoff is also important because the water that goes under the ground could water some roots of a tree and keep it from dying and keeping the environment healthy. Once the water that went over the land goes back into the sea this process starts again.
In the water cycle there are 3 key facts about it, number 1 is that water is always recycled we never get new water because when it rain it's from the sea and the sea water is from when it rains! Number 2 is that the water cycle never ends or starts it just keeps going around like a circle. Number 3 is that there are 3 forms in the water cycle liquid, solid and gas. The gas is when it's a cloud in the sky, the liquid is when it's raining or in the sea, and it's a solid if it snows or ice.
