Weather changes when the temperature and the amount of water in the
atmosphere change. We can see and feel water coming from the atmosphere when we
have rain. But the water must somehow get back to the atmosphere.
Meteorologists call this the water cycle.
There are many stages
in the water cycle. Rain falls when water vapour in clouds condenses(凝结). Drops of water
form and fall to the ground. The water soaks into the ground and feeds streams
and rivers. A lot of rain falls into the sea. The heat of the sun evaporates
some of the water in the ground and in the rivers, lakes, and the sea. It
changes the liquid water into water vapour. The vapour rises onto the air.
Water vapour is normally invisible. On a very damp or humid day, however, you
can sometimes see water vapour rising from a puddle(水坑) or pond in a
mist(薄雾) above the
water. Water vapour also gets into the air from living things. Trees and other
plants take in water through their roots and give off water vapour from their
leaves. People and land animals drink water and breathe out water vapour. In
all these ways the water returns to the air. There it gathers to form clouds
and condenses to form rain. The rain falls to earth, and the cycle starts
again. It continues even if snow or hail(冰雹) fall instead because both
eventually melt to form water. The amount of water vapour in the air depends on
the temperature. The air is more moist(潮湿) in the tropics(热带) than in the
cold polar regions.
