Question

Explain why rusting of iron
object is faster in coastal areas than in desert
​

Answer 1

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.

Answer 2

Answer:

When some metals get in contact with water or atmosphere oxidation occurs. This is due to the humidity present in the air. Process of oxidation occurs in metals like iron, copper, aluminium etc., . Atmosphere in the coastal area contain more of humidity than in non coastal areas like deccan plateaus etc.,

When iron metal is in contact with the air in the coastal area, due to the presence of high humidity in the atmosphere iron metal rusts faster.
