9. Mirage is due to: A.Unequal heating of different parts of the atmosphere B.Magnetic disturbances in the atmosphere C.Depletion of ozone layer in the atmosphere D.Equal heating of different parts of the atmosphere
Answer: Option A Solution: Mirages happen when the ground is very hot and the air is cool. The hot ground warms a layer of air just above the ground. When the light moves through the cold air and into the layer of hot air it is refracted (bent). A layer of very warm air near the ground refracts the light from the sky nearly into a U-shaped bend.
