Final answer:
The aurora, also known as the northern and southern lights, is caused by charged particles from the solar wind interacting with Earth's magnetic fields.
Step-by-step explanation:
The statement that Earth's aurora is caused by sunlight reflecting off of ice crystals in our atmosphere is false. The aurora, also known as the northern and southern lights, is caused by charged particles from the solar wind interacting with Earth's magnetic fields. When these charged particles collide with molecules in the Earth's atmosphere, they cause the molecules to glow, producing the beautiful curtains of light that we see as the aurora.
