Auroras are natural light displays that occur in the Earth’s upper atmosphere. The interaction of charged particles and Earth’s magnetic field causes the formation of auroras.
- The Northern Lights are located near the North Pole, whereas the Southern Lights are near the South Pole.
- The thermosphere is the layer of the atmosphere where auroras occur.
- The colours of auroras are determined by the type of gas particles involved in the collisions, as well as their altitude in the atmosphere.
