Chapter 9Erosion and Deposition
Review terms and ideas______________ is the material moved by erosion.SEDIMENTWhat materials does sediment consist of?PIECES OF ROCK/SOIL AND PLANT AND ANIMAL REMIANS
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
______________ IS THE FORCE THAT PULLS ROCK AND OTHER MATERIALS DOWN HILL.GRAVITYTHE FOUR TYPES OF MASS MOVEMENT INCLUDE __________,____________,____________, &____________LANDSLIDES, MUDFLOWS, SLUMPS, AND CREEPS.

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
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
MORE RUNNOFF=MORE?EROSION!
FEATURES CREATED BY RUNOFF: THESE ARE?

EROSION BY RIVERSTHROUGH EROSION, A RIVER CREATES VALLEYS, WATERFALLS, FLOOD PLAINS, MEANDERS, AND ____________ LAKES.OXBOW
THIS IS AN EXAMPLE OF?
THIS IS AN EXAMPLE OF?
WATERFALLSHOW ARE WATERFALLS FORMED?A RIVER FLOWS OVER AN AREA OF HARD ROCK THAT ERODES SLOWLY, THEN OVER A SOFT ROCK THAT ERODES MORE QUICKLY.
WHAT IS THIS AN EXAMPLE OF?
THIS IS AN EXAMPLE OF?
MEANDERWHAT CAUSES A MEANDER?WATER FOLLOWS THE COURSE OF LEAST RESISTANCE. IT WILL FLOW FIRST WHERE ROCK/SEDIMENT IS EASIER TO ERODE.
WHAT IS THIS AND WHY DID IT FORM?
OXBOW LAKEUSUALLY FORM DURING FLOODS WHEN WATER FINDS AN EASIER WAY DOWNSTREAM AND CUTS OFF THE OLD MEANDER.
WHAT IS THIS AN EXAMPLE OF?
ALLUVIAL FANSSTREAMS FLOW OUT OF A STEEP NARROW MOUNTAIN VALLEY AND SUDDENLY SPILL INTO AN OPEN, FLAT AREA OR WATER SOURCE
WHAT AND WHERE?
DELTAEXPLAIN 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.
