  1. Chapter 9 Erosion and Deposition

  2. Review terms and ideas • ______________ is the material moved by erosion. • SEDIMENT • What materials does sediment consist of? • PIECES OF ROCK/SOIL AND PLANT AND ANIMAL REMIANS

  3. REVIEW TERMS AND IDEAS • ______________ OCCURS WHERE THE AGENTS OF EROSION, DEPOSIT, OR LAY DOWN, SEDIMENT. • DEPOSITION • ____________,_____________, &______________ ACT TOGETHER IN A CYCLE THAT WEARS DOWN AND BUILDS UP EARTH’S SURFACE. • WEATHERING, EROSION, AND DEPOSITION

  4. ______________ IS THE FORCE THAT PULLS ROCK AND OTHER MATERIALS DOWN HILL. • GRAVITY • THE FOUR TYPES OF MASS MOVEMENT INCLUDE __________,____________,____________, &____________ • LANDSLIDES, MUDFLOWS, SLUMPS, AND CREEPS.

  6. Moving ___________ is the major agent of erosion that has shaped Earth’s land surface. • WATER • _____________is water that moves over Earth’s surface that carries particles with it. • RUNOFF

  7. The amount of runoff in an area depends on 5 main factors which are? • AMOUNT OF RAIN, VEGETATION, TYPE OF SOIL, SHAPE OF THE LAND, HOW PEOPLE USE THE LAND

  8. MORE RUNNOFF=MORE? • EROSION!

  9. FEATURES CREATED BY RUNOFF: THESE ARE?

  10. THIS FEATURE IS?

  11. THIS FEATURE IS?

  12. THIS FEATURE IS?

  13. THIS FEATURE IS?

  14. EROSION BY RIVERS • THROUGH EROSION, A RIVER CREATES VALLEYS, WATERFALLS, FLOOD PLAINS, MEANDERS, AND ____________ LAKES. • OXBOW

  15. THIS IS AN EXAMPLE OF?

  16. THIS IS AN EXAMPLE OF?

  17. WATERFALLS • HOW ARE WATERFALLS FORMED? • A RIVER FLOWS OVER AN AREA OF HARD ROCK THAT ERODES SLOWLY, THEN OVER A SOFT ROCK THAT ERODES MORE QUICKLY.

  18. WHAT IS THIS AN EXAMPLE OF?

  19. THIS IS AN EXAMPLE OF?

  20. MEANDER • WHAT CAUSES A MEANDER? • WATER FOLLOWS THE COURSE OF LEAST RESISTANCE. IT WILL FLOW FIRST WHERE ROCK/SEDIMENT IS EASIER TO ERODE.

  21. WHAT IS THIS AND WHY DID IT FORM?

  22. OXBOW LAKE • USUALLY FORM DURING FLOODS WHEN WATER FINDS AN EASIER WAY DOWNSTREAM AND CUTS OFF THE OLD MEANDER.

  23. WHAT IS THIS AN EXAMPLE OF?

  24. ALLUVIAL FANS • STREAMS FLOW OUT OF A STEEP NARROW MOUNTAIN VALLEY AND SUDDENLY SPILL INTO AN OPEN, FLAT AREA OR WATER SOURCE

  25. WHAT AND WHERE?

  26. DELTA • EXPLAIN HOW A DELTA IS FORMED. • SEDIMENT THAT IS DEPOSITED BY A RIVER THAT FLOWS INTO A LAKE OR OCEAN BUILDS UP INTO A LAND FORM.
