A Look at How Landforms are the Result of Changes to Earths Surface by Water, Wind, and Ice
In your science notebook, write a description of how you would describe a landform to another student. Although there are many different landforms, in this lesson, we will focus on three specific landforms.
Sand dunes form by… Sand dunes change by…
The wind reshapes the rock by…
Flowing water changes the rock by…
Canyons form by… Canyons change over time by…
Deltas form by… Deltas change over time by…
Waves change the rock by…
Over time, waves can change…
Ice can change rock by…
Mountains can be reshaped by…
Are all Earths 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?
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? Which forces caused these landforms to change? How do the landforms that are formed and changed by water, wind, and ice differ from each other?
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
