The term 'Polar Display' is a type of natural phenomenon that occurs in the polar regions of the Earth. It is also known as an Aurora, which is a 6-letter word that is used to describe the colorful lights that appear in the night sky. These lights are caused by the interaction of charged particles from the sun with the Earth's magnetic field. The colors of the lights vary depending on the type of particles involved and the altitude at which they occur. Polar displays can be seen in both the northern and southern hemispheres, and are often seen during the winter months.
