BUT WHERE DOES THE WATER GO????Subtitle Here
![Page 3: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/3.jpg)
BUT where does water go???• All of these water sources are
connected through the WATER CYCLE…
• But they are also connected through something called DRAINAGE…

WHERE DOES THE WATER DRAIN TO?

Drainage Basins/Watersheds
![Page 6: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/6.jpg)
Drainage Basins/Watersheds
• An area of land where all water flows to a central river and then eventually to the ocean
But how does it know which way to go?
Divide = high ridge of land from which water will flow in different directions
(from high elevation to low)
![Page 7: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/7.jpg)
Which Drainage Basin are we in?
• Catawba River Wateree River Santee River Atlantic Ocean!

Watershed Activity:
• Create your group’s village on the white piece of paper showing the following things:− Black marker: main streets and buildings− Blue marker: rivers or creeks− Green marker: grass and trees− Brown marker: exposed soil that could
erode− Red marker: pollutants from cars, people,
and animals• Crumple up piece of paper & open to represent your village• Add water source with mist of water!

Watershed Discussion:• If this is a model of a
watershed…−What do the creases in the
paper represent?−What happens to the ink from
the markers as the water flows?−Where will the water eventually
go?−Where will the ink eventually
go? Highest or lowest place?− Are there any problems you see
with this watershed?

DOES ALL OF THIS WATER THAT DRAINS AWAY ALWAYS STAY ON THE SURFACE?
![Page 11: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/11.jpg)
Groundwater:• Groundwater:
− is water that soaks into the soil and collects underground
• Water Table: • - the top layer of • ground water
![Page 12: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/12.jpg)
HOW DOES THE WATER GET IN THE GROUND?
![Page 13: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/13.jpg)
Groundwater:• Through ___________, water
soaks into the ground, but groundwater can only occur closer to the Earth’s surface.
Why?
![Page 14: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/14.jpg)
Groundwater occurs in the layers of the Earth where there are spaces between the rock.Permeable:• A substance that
allows water to flow through it
• loose rock & sediment
Impermeable:
• A substance that does NOT allow water to flow through it
• solid rock
![Page 15: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/15.jpg)
Permeable vs. Impermeable:

WHERE IS GROUNDWATER STORED?
![Page 17: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/17.jpg)
Groundwater is stored in AQUIFERS…
• Aquifer:−A permeable rock layer that
stores water and allows water to flow through it
![Page 18: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/18.jpg)
HOW DOES GROUNDWATER COME TO THE SURFACE?
![Page 19: Where does water go?](https://reader035.fdocuments.in/reader035/viewer/2022081520/56816202550346895dd2271a/html5/thumbnails/19.jpg)
Groundwater comes up!
• Spring:− Water that
naturally flows out of the ground because it is below the water table
• Well:− A hole in the
ground that reaches down to the groundwater in aquifers
(Can be natural or synthetic)

Tie it together!• WATER CYCLE tells us where water
comes from. Today, we discussed where water goes.
• Dear Diary… – Imagine you are a water molecule and you are writing in your diary. Explain the journey you take through the water cycle and what is happening to you along the way.
• Must include watershed, groundwater, and
aquifer AND the steps of the water cycle.
