Question

Why is rusting faster in coastal areas than in deserts

Answer 1

$\huge \pink{answer}$

For rusting, the presence of air(oxygen) and moisture(water) is required. In coastal areas the quantity of moisture present in air is higher than in the deserts. Hence, rusting of iron objects is faster in coastal areas than in deserts.

Solution:
Rusting of iron requires contact with water (moisture) and oxygen. In coastal areas, humidity is more in comparision to that in deserts; hence, rusting of iron objects is faster in coastal areas than in deserts.
