What Causes a Mirage to Happen?

A mirage is when the air makes things look like they’re not there. Imagine you're walking through a hot desert, and you see what looks like water in the distance, but it disappears as you get closer. That’s because the hot ground warms up the air near it, and that warm air bends light from far away, making things look like they’re in places they’re not.
