1. Erosion and Weathering In our life

2. Weathering by water.

3. Can you see a crack that made by the rain and snow that went into the crack? They broke the crack to be bigger.

4. Cracks on the ground is made by gravity and water that froze.

5. The crack of pipe is made because the weather is so cold that water inside of pipe froze so the volume of pipe got bigger.

6. Those cracks are made by the biological and water because the snow and rain drops went in and the cracks by biological got bigger.

7. Cracks of rocks are made by frozen water and sudden change of weather.

8. Rocks became really smooth and round because of waves making the rocks to hit each other to make it smoother. This is weathering not the erosion.

9. Erosion by gravity By the weight of the building, the wall got a long crack.

10. Biological weathering The roots of tree and plants are breaking the rock down.

11. Chemical weathering See the yellowy part of the manhole. It is eroded.

12. It shows the chemical weathering because the iron part is eroded by some chemical in the rain.

13. Acid rain ruined the colours of the buildings which is erosion.
