Upper course, middle course, lower course

Vertical (downward) erosion

Lateral erosion and transportation

Deposition

High, mountainous areas

Where a tributary meets the main river

River winds around harder rock, erodes softer rock

Meander cut off from main river

Fresh water mixes with saltwater

Force of water erodes, pressure breaks rock apart

Rocks grind against bed/banks like sandpaper

Rocks break into smaller, smoother pieces

Smaller particles bounced along riverbed

Natural embankments made of alluvium (sediment)
