The water cycle (or hydrological cycle) is the cycle that water goes through on Earth. Then, the water falls from the sky as rain, snow, sleet or hail. This is called precipitation. The water sinks into the surface and also collects into lakes, oceans, or aquifers. It evaporates again and continues the cycle. Water cycle is defined as the way that water moves between being water vapor to liquid water and then back to water vapor. An example of water cycle is when water evaporates from oceans and then returns to the land in the form of rain. There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. 1) Evaporation. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air. We have already learnt about transpiration, did...
