DO NOW: Take our LIE Hurricane Article and Notes from Friday.

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 / ALLUVIAL FAN forms

The other factor affecting Stream Velocity is: _____________________ Discharge

Stream Velocity ___ Discharge Slope Stream Velocity ___ Kinetic EnergyStream Velocity ___ Particle Size Stream Velocity ___

State the relationship between Erosion and Deposition. Erosion- Deposition-

Factors That Affect Deposition:

Which will be deposited First?

Sediment Shape: Which will be deposited FIRST? Why?

Which Mineral will be deposited First? Why? MineralDensity Quartz2.65g/cm3 Halite2.16g/cm3 Galena7.60g/cm3

RELATIONSHIPS Deposition Increases when …. Sediment Size ___ Roundness ___ Density ___ Velocity ___ Slope ___ Discharge ___
