When it Rains it Pours Todays Goal: To understand how water is absorbed into the ground. To be able to explain the difference between pervious and impervious surfaces. To learn about watersheds and storm-water runoff.
When it Rains it Pours When it rains, water can do one of three things. It can… on vegetation and evaporate soak into the ground over the surface of the ground
When it Rains it Pours The rains ability to absorb into the ground depends on if the ground is pervious or impervious In other words,... Can the rain get through the surface or not?
When it Rains it Pours If the ground is pervious, such as a grassy lawn, a forest, or a field, the rain can easily soak into the ground
When it Rains it Pours If the ground is impervious, such as concrete driveways and sidewalks, asphalt roads and parking lots, and rooftops of houses, the rain cannot soak into the ground
When it Rains it Pours When water soaks into the ground, the grounds sand and soil act as a natural filter
When it Rains it Pours When water runs over impervious surfaces, it picks up all kinds of pollution along the way
When it Rains it Pours Everyone lives in a watershed
When it Rains it Pours A watershed is the land where all of the water drains to a specific location
Mississippi Cumberland Big South Fork Ohio Bear Creek, Roaring Paunch Creek and Big Creek are part of the Big South Fork Watershed.... Which is part of the Upper Cumberland Watershed... Which is part of the Ohio River Watershed.... Which is Part of the Mississippi River Watershed. BIG SOUTH FORK TO THE MISSISSIPPI RIVER
When it Rains it Pours 41% of the United States eventually drains into the Mississippi Watershed which then empties into the Gulf of Mexico Thats almost HALF of the entire United States! Wow! Mississippi
When it Rains it Pours The key idea is that EVERY drop of rain flows somewhere
When it Rains it Pours Kentucky is divided into 8 major watersheds.
When it Rains it Pours Whether or not our watershed becomes polluted is largely up to US...... because if its on the ground, its in your water Protect Our Water
