34.Have you ever wondered where the rain comes from,or how the clouds are formed?Well,this is what the water cycle(循環(huán)) is all about. When the sun heats up the rivers and oceans,water becomes water vapour(蒸汽) and it rises up in the air.This process is called evaporation.It is the first step of the water cycle.You can also see water vapour at home!Just tell your mommy to heat some water.And as the water gets heated,you'll be able to see the water vapour rising up in the air. When the water vapour reaches up in the sky,it turns into tiny droplets(小滴) of water.These water droplets,along with various gases and dust particles(塵粒),come together to form clouds.This is known as condensation.Now,hold a cold lid over the vessel(容器) in which you heated water.When you open the lid after some time,you'll be able to see water droplets on the lid.That's exactly what condensation is! When the cloud becomes too heavy and it cannot hold any more water inside,it bursts open to give out rain,hail or snow.This is known as precipitation. As it rains,water gets collected in oceans,lakes and rivers.It even seeps(滲透) through the soil and becomes ground water.Thus the water cycle is a continuous process of evaporation,condensation and precipitation.
