Lesson Worksheet: Changes to Earth's Surface: Erosion, Weathering, and Deposition Science • 2nd Grade
In this worksheet, we will practice identifying, classifying, and describing slow changes to Earth’s surface.
Choose the correct definition of weathering.
- AThe process where rocks are dissolved, worn away, or broken down
- BThe process where rocks are moved from one place to another by ice, water, wind, or gravity
