THE WATER CYCLE

WHAT IS THE WATER CYCLE?

There is the same amount of water on earth now as there was when dinosaurs hung out at the local pond millions of years ago. The water keeps moving in a cycle; it evaporates from rivers, lakes, and oceans. The vapor from evaporation and condensation forms the clouds in the sky and then returns to earth as rain, snow, sleet, or hail.

PRECIPITATION!! When water falls back to earth as

precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land.  When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts

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.

Do plants sweat? Well, sort of.... people perspire (sweat) and

plants transpire.  Transpiration is the process by which plants lose water out of their leaves.  Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.

CONDENSATION!!! Condensation is a process in which water

vapor turns into water droplets it comes in contact with a cooler surface.

FUN FACTS ABOUT THE WATER CYCLE!!!

Water is essential to our planet’s life without it we couldn’t survive. The globe is two-thirds covered by water but 93% is ocean water which is toxic to humans , plants , and animals.
