Question

Why does the air above a farm land during hot summer?

Answer 1

If we pass through a farmland during a hot summer day, we will see that the aire above the soil is shimmering(shining with slightly shaking light). This happens as follows: The soil in the farmland contains some water.On a hot summer day, this water of soil evaporates to form water vapour.The water vapour coming out of the soil reflects the sunlight irregularly due to which the air above the soil seems to shimmer.
