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

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.

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
