The Water Cycle

The Water CycleBy Melissa Alsip

Correct!!!Evaporation, condensation, and precipitation are all steps in the water cycle.

Learning ObjectiveIn this lesson we will be learning to identify the basic features of the water cycle and describe their importance to life on earth. We will also be able to recognize the major components of the water cycle.

QUIZEXITWhat is the Water Cycle?The cycle of evaporation and condensation controls the distribution of the earths water as it evaporates from bodies of water or land. The water evaporates, condenses, precipitates, runs-off, infiltrates, transpires, and finally returns to bodies of water or land. The water cycle is an important part of our everyday lives! With out the Water Cycle the earth could not reproduce water for us to survive!

QUIZEXITFun Fact!!Almost all of the water on the planet has been here since the earth was formed!We may even be drinking water that Dinosaurs drank!!

QUIZEXITThe Stages of the Water CycleEvaporation/TranspirationCondensationPrecipitationRun-offInfiltration

QUIZEXITEvaporationThe Sun plays an important part in the water cycle, without it there would be no water cycle!The Sun causes water on the surface of oceans, rivers, lakes, and ground to evaporate in to the sky. Evaporation causes the air to cool.

QUIZEXITTranspirationWater is absorbed through the roots of plants and moves up through hollow tubes to the leaves. Leaves have small holes in them through which they can absorb carbon dioxide and release oxygen. Water vapor is also lost through evaporation from the pores of the leaves.

QUIZEXITCondensationAs the air containing the water vapor rises, it cools and the vapor begins to condense into clouds. The process of condensation releases heat back into the atmosphere moving the clouds to new locations, the heat is redistributed across the earth. The water drops on a glass can be identified as condensation.

QUIZEXITPrecipitationClouds can produce rain, hail, snow, or sleet. Water that falls from the atmosphere in these forms is called, Precipitation.

QUIZEXITRun-OffA lot of the water falling as rain can run off the ground surface either into rivers, lakes, or into the ocean. Any additional water will be forced to run over the surface as Run-Off. Nearly 40% of all precipitation flows back across the land to seas and oceans.

QUIZEXIT12InfiltrationWhen so much water has infiltrated the ground that no more can soak in, then it is said that the ground has reached saturation point. Some of the water which infiltrates into the ground ultimately returns to the surface as springs or lakes and can also drain into river systems below the surface of the river flow. Some of the infiltration water will remain underground as Groundwater.

QUIZEXITQuick ReviewWater falls either into rivers, lakes, into the ocean or on the ground.Ground has reached saturation point.Causes the air to cool.Releases heat back into the atmosphere.Is absorbed through the roots of plants.Water that falls from the atmosphere in forms of rain, hail, snow, or sleet.QUIZEXITNow that you have be come a Water Cycle Master:

Lets Test Your Knowledge!!

QUIZEXITSorry.Try Again!!Look for an answer that is something that provides heat.

Question 2What is evaporation?

A. Water freezesB. Water vapors meet cold air and changes back into liquidC. Water gets warm and changes from liquid water to water vaporD. Plants take in water from the soilSorry.Try Again!!Think about what water becomes when it evaporates.

Question 3What is the correct term for moisture that falls to the ground from clouds?

A. CondensationB. PrecipitationC. HibernationD. EvaporationSorry.Try Again!!This can be in the form of rain, hail, sleet, or snow.

Question 4Which are three stages of the water cycle?

A. Evaporation, condensation, precipitationB. Condensation, precipitation, hibernationC. Precipitation, dehydration, evaporationD. Transpiration, dehydration, condensationSorry.Try Again!!All three stages involve water.

Question 5What is the correct term for plants releasing water from their leaves, which then evaporates?

A. EvaporationB. PrecipitationC. TranspirationD. CondensationSorry.Try Again!!Remember the water is taking a ride through the plant.

Question 6Rain that returns to lakes or oceans is referred to as_________.

A. PrecipitationB. RunoffC. CondensationD. Evaporation

Sorry.Try Again!!Think about what the water does when it rains.
