Answer 1

Answer:

The rusting of iron is a common example of it which occurs due to reaction with oxygen. Hence, rocks containing iron compounds easily absorb oxygen from air & forms new chemical compound like iron oxide.

Explanation:

Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
