Difference between Weathering and Erosion

Weathering and erosion are often used interchangeably. This lesson will help the students understand and differentiate these two processes. Simply put, weathering breaks down the rock through either chemical or physical means. Abrasion, frost wedging, thermal stress, hydrolysis, carbonation, and oxidation are some of the methods for weathering. Erosion, on the other hand, is a process through which rocks are moved from one place to another. Wind, water, and gravity are some of the means for this displacement of rocks. The core idea is that weathering breaks the rocks, while erosion carries this rock away.

This video satisfies the 4-ESS2-1 requirement of fourth-grade science proficiency.

Students who demonstrate understanding can: 4-ESS2-1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.
