Do Now

Describe the relationship between the factors listed below

1. Stream Velocity and Slope

2. Stream Velocity and Discharge

3. Stream Velocity & Sediment Size

How can we go downhill faster? On a bike, rollerblades, sleds,

ski’s…

Who will move FASTER? Why_____________

1. SLOPE / GRADIENT( steepness):

Slope _______;Stream Velocity ( ) ____;Kinetic ( ) Energy _____;Transported particle size _____.

Where do rivers travel FASTEST?At the Source or the Mouth?

FASTEST = SOURCE ;

STEEPER= EROSION

SLOWEST = MOUTH

FLATTER=DEPOSITION

DELTA /
