Question: What are the scientific names for the Northern Lights and Southern Lights?
Answer: Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights)
Card 2
Question: What causes the spectacular natural light displays known as auroras?
Answer: Charged particles from the solar wind (primarily electrons and protons) are trapped by Earth's magnetic field.
Card 3
Question: Which force guides the charged particles from the solar wind along the magnetic field lines towards the magnetic poles?
Answer: The Lorentz force
Card 4
Question: How do auroras emit light?
Answer: The charged particles collide with atoms and molecules in the upper atmosphere, exciting them and causing them to emit light.
