Intro
Objective 12/06/11
Explain how landforms are created through erosional processes
How is erosion different from weathering?
EROSIONAL LANDFORMS
Erosional Landforms
Erosion A gravity driven process that moves solids (sediment, soil, rock and other particles) from their source and deposits them elsewhere.
Erosional Landforms
What causes erosion?
Mostly water and wind Rain, snow, sleet Ice, glaciers Rivers, streams Ocean waves
Erosional Landforms
Rain, snow, sleet (weather)
Dissolves rock, freezes and expands rock, or washes rock away
Erosional Landforms
Ice, glaciers Sediment picked up into the glacier and carried
Erosional Landforms
Rivers & Streams Cut through the landscape, move rock from one place to another
Erosional Landforms
Ocean Waves Erode the shorelines of the land with power and force
Erosional Landforms
Shoreline Erosional Landforms
Headlands Sea Cave Sea Arches Sea Stacks Wave Cut
Terrence Beaches
Headlands
Sea Caves
Sea Arches
Sea-Stacks
Wave-cut Terraces
Beaches
Erosional Landforms
What happens to eroded rock?
Rock that is eroded is carried towards the ocean as sediment Becomes sand Becomes deltas Becomes sea-bed
Erosional Landforms
Ways to stop sand movement:
Groins Jetties Breakwaters
Erosional Landforms (Groins)
Erosional Landforms (Jetties)
Erosional Landforms (Breakwaters)
Erosional Landforms
Summary: What is erosion? What causes erosion? What are some shoreline erosional
landforms? What are some ways to stop our shorelines
from eroding away?
Objective 12/06/09
Outro
Explain how landforms are created through erosional processes.
Using a Flow-Map, show how headlands can eventually become beaches.
