But its effects extend far beyond its visible surface. Great storms on the sun send gusts of charged solar particles hurtling across space. If Earth is in the path of the particle stream, our planet’s magnetic field and atmosphere react.

-When the charge particles hit them, they gain energy.

Atoms consist of a central nucleus and a surrounding cloud of electrons encircling the nucleus in an orbit. When charged particles from the sun strike atoms in Earth’s atmosphere, electrons move to higher-energy orbits, further away from the nucleus. Then when an electron moves back to a lower-energy orbit, it releases a particle of light or photon.

Electricity is used to excite the atoms in the neon gas within the glass tubes of a neon sign. That’s why these signs give off their brilliant colors.]]> 2017-01-15 02:50:42 UTC https://padlet.com/s68096/6gz2ku0tomci/wish/147213626 s68096 https://padlet.com/s68096/6gz2ku0tomci/wish/147961462 2017-01-18 21:37:50 UTC https://padlet.com/s68096/6gz2ku0tomci/wish/147961462
