  1. Deposition

  2. Deposition • Once material is picked up and ___________ it must be __________. Deposition is the ___________ of sediments from an erosional system. Deposited eroded release

  3. Deposition • Factors that affect deposition are ___________, _____________, __________ and the __________ of the transporting medium. particle size particle shape density velocity

  4. Deposition • Particle Size-All factors being equal, _________ particles settle ___________ than smaller ones. • In running water smaller particles will stay in _________ longer. • As the water slows, ________ particles will settle __________. Larger faster suspension larger first

  5. Deposition vertical • This is called _____________ sorting. Particles will settle as follows: smallest largest

  6. Deposition What would 3 series of depositional events look like?

  7. Deposition • Particle Shape-If all other things are equal, ________ particles will settle _________ than _________ objects. round flat faster fast slow

  8. Deposition denser • Particle Density- The ________ the particle the __________ the particles will settle. faster

  9. Deposition • Stream Velocity- The _______ the stream is moving, the ________ the larger particles will stay in suspension. • On your ESRT there is a stream velocity chart. _______ size particles are the _________ and boulders are the _________. faster longer clay smallest largest

  10. Deposition • Different stream velocities will deposit different size sediments. • As a stream reaches a lake the velocity of the water _________. Particles will get deposited according to the criteria above. slows

  11. Deposition Boulders, pebbles silt clay precipitates and sand horizontal Here we see ____________ Sorting. This has the larger, heavier particles settle ______. first

  12. Deposition • How a stream deposits sediment depends on shape and velocity. • As a stream turns around a bend, the ___________ moving water is on the __________ edge. • Here we see greater erosion. faster outside

  13. Deposition slower • The inside edge has ___________ moving water and greater _______________ rate. deposition Outside edge-Erosion is greater than deposition LAKE Inside Edge-Deposition is greater than erosion

  14. Deposition • There will also be __________ where the __________ meets the lake because the water velocity is ____________. Here we see _____________ sorting. • If this process continues over many years, an __________ lake will form. deposition stream decreasing horizontal oxbow

  20. Deposition • Glacial deposition is slightly different. Glaciers are so big, that they have the ability to carry any amount of any size particle. When the glacier melts, the material left behind is ________________. unsorted
