Water: Its Important!Mr. EllisDo NowWhy do you think water is important? What does it do for you?How Much Water?So, the planet is made of 70% water, that means that we have SO much? Right?Well, not necessarily.Although we have a lot of water, not all of it is readily available for use. A lot of this water is trapped.Question 1Write down how you think the water is trapped?Ocean WaterApproximately 97% of all water is found in the Oceans of the world. Is this water usable*?Question 2What does usable mean?Salt WaterSalt Water97% of the Earths waterWe cannot drink this water, or use it to water most plant life.We can only use this water if we use a very expensive process called Desalination*.Fresh Water*3% of the Earths waterWe know that we can drink fresh water. But theres still some problems with fresh water. Some of it is trapped*. Lets find out how its trapped.Most Fresh is FrozenSo we have 3% fresh water. But most of this is trapped.Most of the fresh water is trapped in Ice.This includes Glaciers, Snow, and Ice Caps.Of the 3% of Fresh Water, Running Out of WaterOK, so I think we might have a problem.If most of the fresh water is trapped in ice, how much do we have for drinking, agriculture, and life in general?So where do we get our fresh water from?Ground Water*Some fresh water is found in the ground.Does anyone have a well at home?Has anyone dug a whole in the ground, and water started to come up?Of the Surface Water*Surface water is water that is readily available for use. Examples: Ponds, Lakes, Rivers, Streams, PuddlesOf the 3% of fresh water, .3% is Surface water. .3%So what have we learned?Even though Earth has a lot of water, we cannot use most of it.Most of it is trapped in the oceans, ground, or is frozen. Only a very small amount, .3%, is able to be used by life (fresh water). So we need to preserve as much water as possible!ConclusionThe Earth is 70% Water97% is Salt Water (we cant drink this)3% is Fresh Water
