which is least affected by chemical weathering

Question

1. a pile of tiles made of feldspare
2. a bridge made of iron rods
3. a chair made of plastic
4. a statue made of marble

Answer 1

Among the options provided, the least affected by chemical weathering would be a chair made of plastic.

Plastic is a synthetic material that is generally resistant to chemical reactions, making it less susceptible to chemical weathering compared to the other materials listed:

1. Feldspar (tiles) can undergo chemical weathering through hydrolysis.
2. Iron (bridges) can rust when exposed to moisture and oxygen, which is a form of chemical weathering.
3. Marble (statues), being composed primarily of calcite, can react with acidic conditions, leading to chemical weathering.

Therefore, plastic is the most resistant to chemical weathering among the choices given.
