Landforms on Earth Brainstorm with a shoulder partner on the definition of a landform?
In this lesson, we will specifically study sand dunes, canyons, and river deltas Landforms
Erosional / Weathering Agents What is a erosional agent? Any naturally occurring phenomena that moves earth materials What is a weathering agent? Anything that causes the breakdown of rock.
Erosional / Weathering Agent: Wind
Erosional / Weathering Agent: Running Water
Erosional / Weathering Agent: Waves
Erosional / Weathering Agent: Ice
Landforms on Earth Are all Earth’s landforms the same? Why or why not? What are some of the features that you see when you look at the pictures? Do you think that these landforms have always been the same? Do you think that changes in these landforms occurred quickly or did they take a long time to be formed?
Landforms on Earth How will these landforms look: –two days from now, one year from now? –ten years from now? –one hundred years from now? –one thousand years from now? –one million years from now? What force caused these landforms to change? Do you think that water, wind, or ice may have created some of these landforms? Which landform was created by which erosional / weathering agent?
Landform Defined In your science notebook, write a definition for the word “landform.” Landform - Any feature on the Earth's surface, caused by erosion, sedimentation, or movement of material by wind, water, or ice
