Bell Ringer List 2 landforms we discussed yesterday.
I can describe where a river begins. I can name the watershed in which I live. I can describe how a watershed works.
Recall yesterday • We used the Frayer vocabulary model to discover our definition for landform. • We jogged your memory using the KWL chart. • Today we continue with landforms (list next slide) • Page 240-241 in your text
What is the difference? Earth landforms Earth’s water features Ocean Coast Tributary River Waterfall Lake Estuary Delta Inlet • Mountain • Hill • Valley • Canyon • Cliff • Plain • Plateau • Desert • Beach • dune
What is a watershed? • A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place.
Watershed Locator • Your watershed • To find your watershed click the link above.
Next ProjectDesign and make a watershed! • 12-16-09 *DUE DATE* Individual or group • 12-02-09 Paper work for your watershed. (instructions, rubric (how you will be graded, hints on materials) • 12-04-09 Diagram of your watershed! • 12-08-09 Written description (How will you make your water shed?)
Where do rivers all begin? • Runoff- • Rain (some evaporates immediately, some soaks into the soil, the remaining flows over the ground surface) • Snow melting • Ice melting
What affects runoff? • 1. the type of ground surface • 2. the rate of rainfall • 3. the slope of the land
What do all of these photo’s have in common? All of the water is running downhill.
Let’s start small • Tributaries—are the smaller streams and rivers that feed into a larger river. • River systems—a river and all its tributaries together make up a river system. • Flow downhill to the pull of gravity
Think about a bathtub • Where does the water go when you pull the plug???
Exit Question---- • Choose 1 to answer • A. Describe where a river begins. • B. Describe a watershed.
