Educational worksheet for sorting weathering, erosion, and deposition processes.

- Weathering: Water entering the cracks of rocks, freezing then thawing; Rain washing away sand from a sand dunes; Acid rain dissolving underground limestone; Wind blowing sand from one place to another; Sand dunes forming as the desert; Rock breaking apart due to temperature changes (implied by “Wind blowing sand” and “Sand dunes forming” which involve breakdown and movement of particles); Layers of sediment forming as the bottom of the ocean (if referring to breakdown of parent rock into sediment).
- Erosion: Glaciers scraping rocks amongst the Earth’s surface; Rainwater carrying away soil from a hill; Waves dropping sand onto forming sand bars; Wind blowing sand away from sand dunes; Wind blowing sand and rock and carving out arches; River carrying sediment downstream (implied by “Deltas developing as the mouth of a river” — erosion upstream enables deposition at delta).
- Deposition: Waves dropping sand onto forming sand bars; Deltas developing as the mouth of a river; Layers of sediment forming as the bottom of the ocean; Sand dunes forming as the desert; Rain washing away sand from a sand dunes (if interpreted as sand being deposited elsewhere); Wind blowing sand from one place to another (if final resting place is implied).
