  1. What is do you mean by the Water cycle? The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.

  2. What are the 4 stages of the water cycle? There are four main parts to the water cycle: • Evaporation • Condensation • Precipitation • Collection

  3. Evaporation:When the sun heats the surface of seas, lakes, rivers and streams, some of the water changes state and becomes water vapour, mixing with the air. Warm air rises so the water vapour rises too. • Condensation:When the air cools down, the water vapour condenses back into water droplets. These water droplets collect together and form clouds. • Precipitation:The water droplets in clouds attract other water droplets to them and they grow bigger. When they get too big and heavy they fall to ground as rain. If the air is cold enough the droplets remain frozen and fall as snow or hail.

  4. Collection: When the water falls to Earth it collects as streams, rivers or lakes. When it falls on land in can filter in to the Earth and become groundwater or it can flow over the land as run off to meet existing bodies of water. Some of the water may be taken up by plants and animals. Plants take up water from the ground through their roots. They then ‘breathe’ the moisture out of their leaves into the air. Evaporation accounts for about 90% of the water in the air with transpiration accounting for most of the other 10%.

  5. Why the water cycle is important? • The hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.

  6. Why is the water cycle important to life? • The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is essential to life.
