earth science western australia weathering & erosion - student worksheet weathering e.g. erosion e.g. see if you can tell the difference (some could be both) example weathering erosion the sun’s heat cracking a rock wind blowing sand from the beach acid rain dissolving marble statues gullies forming under a down - pipe from the gutter avalanche!!!!! skateboarders wearing away tracks on cement walls the expansion of ice on a cold night breaking up a road surface a storm at sea carrying away the beach a river changing its course and cutting into a field

Explanation:

Weathering is the breaking - down of rocks, soil, and minerals through direct contact with the Earth's atmosphere. Erosion is the movement of soil, rock, and dissolved material by natural forces like water, wind, ice, and gravity.

1. The Sun's heat cracking a rock: Physical weathering as heat causes expansion and contraction.
2. Wind blowing sand from the beach: Erosion as wind is transporting sand.
3. Acid rain dissolving marble statues: Chemical weathering as acid in rain reacts with marble.
4. Gullies forming under a down - pipe from the gutter: Erosion as water is carrying away soil.
5. Avalanche: Erosion as snow and ice are moving and carrying material.
6. Skateboarders wearing away tracks on cement walls: Erosion (mechanical) as physical force is wearing away the cement.
7. The expansion of ice on a cold night breaking up a road surface: Physical weathering as ice expansion exerts force.
8. A storm at sea carrying away the beach: Erosion as water and wind in the storm are transporting beach material.
9. A river changing its course and cutting into a field: Erosion as water is moving soil and cutting into the field.
