Answer to Question 1

Answer: The broken glass bottles provide an example of mechanical weathering: to make them, a single glass bottle would have to be shattered into numerous shards of glass. Though many new pieces of glass result, the substance itself (glass) has not been transformed into anything new. In contrast, the rusty cans provide an example of chemical weathering: to make them, an initial can would have to react with oxygen in the atmosphere (an oxidation reaction facilitated by water) and a new substance (rust) would be produced at the expense of the material that composed the original cans.
