Idenify surface water around us!

Open Ended

Where do you think you would find surface water around the world?

The Water Cycle

• We need the Water Cycle to survive

• How water circulates through air, land, and oceans

Multiple Choice

Which of the following do you think is part of the water cycle that we have not talked about?

They are found near the poles

Icebergs break off and melt as they move towards warmer water

Lakes and Rivers

• transportation

• drinking water

• hydroelectric power

Poll

• Water is shed from the land after a rainfall or snow melt

Open Ended

Looking at the image, which watershed do you think has the most impact on us, where we live?

Continental Divide

Wetlands

• An area covered in water for part of all of the year.

• Water is trapped in low areas and fill up in warmer months

• Where groundwater can come to the surface

• They help filter water (yay microbes!)

• Provide Habitat
