== ​__Why Do Mirages Occur?__

Mirages are like ripples in the water, except they are in the air. These ripples in the air are caused by heat and are much harder to see than ripples in the water because air is less dense. The heat transfers to disortions in the light which causes a misleading appearance. A mirage is caused by a reflection of a distant object closer, above, or below the actual object. Reflection is caused by light. In physics, a mirage is called an optical illusion. A mirage can either be superior or inferior. In a superior image, the distant object looks to be upside-down in the sky. An inferior mirage occurs when an object appears to be raised above or below their normal position. This is how a mirage works by reflection. [|inferior mirage]

This is an exapmle of a superior image.
