Question

Rusting of iron objects is faster in coastal areas than in deserts. Why?​

Answer 1

This is because the humidity in coastal areas. Since the more the water content the higher the rusting. But in deserts the water content is very less and thus rusting is slow.

Answer 2

Answer:

because rusting takes place due to the reaction between iron object and moisture of air

in desert the water content in air is very low while in coastal areas the air has high moisture

so rusting takes place faster in coastal areas than in deserts
