northern and southern lights
Storyboard Text
- Hi Jack
- Hello Chris
- Why is it red?
- True, true
- Is that the northern lights?
- I think because it is coming from sun that's why it is red in colour
- I think so
- I wonder, how do the lights actually work?
- Haha that's funny because I actually know the answer
- First, charged protons and electrons from the Sun's surface are shaken from the Sun's gravitational orbit. These particles are moving at around 1 million miles/hour.
- After 40 hours, the winds reach the Earth's magnetic fields and follow the force generated from the Earth's core into the two magnetic poles, the North and South poles.
- Once they reach the atmosphere in the two poles, the particles collide with the oxygen and nitrogen atoms creating the magnificent lights you see at night.
- The colours created depends on which atom is struck, particles colliding with oxygen atoms create green and red lights while the nitrogen atoms create blue and purple lights
- Wow, that's really cool, thanks for teaching me this.
- Anytime
