5 Erosion  moves rock particles
Sediment = rock particles Deposition = when sediment is laid down/deposited from erosion Deposition Landform Weathering Sediment Erosion Deposition

6 Erosion  moves rock particles
Sediment = rock particles Deposition = when sediment is laid down/deposited from erosion Examples: WWGM – “What would G-ma make?” Wind  Water (runoff, rivers, waves) Glaciers Mass Movement (landslides, mudflows, slumps and creeps)

7 Wind Erosion – wind carrying sediment

8 Water Erosion – waves, rivers, streams, waterfalls
wave erosion

9 Glaciers glaciers

10 Mass Movement Examples - gravity
Mudslide Landslide Creeps & Slumps Avalanches US

11 Landform Weathering Sediment Erosion Deposition
