1. Using Satellite images to make predictions of changing landforms

2. Review What is a land feature? What is weathering? What is erosion?
A geological structure created by weathering, erosion, or deposition
What is weathering?
The break up of rock into smaller pieces from ice, plants, abrasion, dissolving or other chemical means
What is erosion?
The moving of land from one place to another by either wind or water
What is the difference?
Weathering is the breakdown of material into smaller material and erosion is the movement of that material
