The Northern Lights - level 2
Normally, the Northern Lights can be seen in Scandinavia, Greenland, Alaska, Canada and Russia. Sometimes, they travel as far south as places like Minnesota, which happened recently.
How do the Northern Lights happen? Sometimes, there are explosions on the surface of the sun. Large amounts of charged particles are thrown into space. Sometimes, they travel towards Earth.
Earth’s magnetic field guides the particles towards the polar regions. As the particles come down, they enter the atmosphere. The particles hit gasses in the atmosphere, and they release energy. This energy can be seen as the Northern Lights.
Difficult words: charged (having an electrical charge), particle (a very small piece of something), guide (to move somewhere).
