Question

Explain why , rusting of an iron objects is faster in areas than in deserts.

Answer 1

Because in desert the air doen't carry much moisture in comparison to other areas. That's why rusting of iron is faster in other areas than desert.

Answer 2

Rusting of iron occurs only if iron comes in contact with moist air. In coastal areas, air contains high percentage of moisture because of sea or ocean, while in deserts air is dry and hot. As the percentage of moisture in air is more in coastal area compared to desert, rusting becomes faster.
