Answers
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. ... Condensation: This is when water vapour in the air cools down and turns back into liquid water. Precipitation: This is when water (in the form of rain, snow, hail or sleet) falls from clouds in the sky.
Answer:
Water from ocean, river, ponds and lakes evaporates all the time. Water evaporates even in winter, when the temperature is low. The water vapour that is formed mixes with the air. The warm summer air being lighter, carries the water vapour upwards. The higher the air go, the cooler it becomes. After reaching a certain height, the air condenses into extremely small water droplets. These droplets together form clouds. As the clouds raise higher, more vapour condenses and collects on the tiny water droplets. the water droplets grow bigger, becomes heavy and ultimately fall downwards as rain. If the temperature close to the land
