What natural phenomenon causes the spectacular light displays known as the Aurora Borealis and Aurora Australis?

💡 Explanation:

The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) are caused by energetic charged particles from the Sun (solar wind) colliding with atoms and molecules in Earth's upper atmosphere. These particles are guided by Earth's magnetic field towards the polar regions, exciting atmospheric gases which then emit light.
