What's the difference between weathering and erosion?

Today's new ELI addresses the common misconceptions about weathering and erosion.

Textbook surveys have shown that misconceptions between weathering and erosion are common, when the scientific consensus is clear:-
- Weathering is the break up and break down (physical break up and chemical breakdown) of rocks at the Earth’s surface without the removal of solid material (although material can be removed in solution)
- Erosion is the removal of solid material, by gravity, water, wind or ice (as the start of transportation).
The related activities on the home page of our website lists some ideas for teaching both weathering and erosion.
