The remaining 2% is oxygen and carbon. ]]> 2016-11-07 21:40:46 UTC https://padlet.com/sn6997/pn7yoi6ow60k/wish/135951111 sn6997 https://padlet.com/sn6997/pn7yoi6ow60k/wish/135951717 The layers of our Sun are the core, right in the middle, then the radiation layer comes, which is surrounding the core. Then there’s the convection layer, which gases with different energies move in circles in a way similar to air with different densities.]]> 2016-11-07 21:43:45 UTC https://padlet.com/sn6997/pn7yoi6ow60k/wish/135951717 sn6997 https://padlet.com/sn6997/pn7yoi6ow60k/wish/135951884 Amazingly, the Sun shoots out heat and energy called, solar flares, stretch out from the corona and chromosphere. Solar flares are very dangerous, and cause power outages. They also create aurora borealis, or northern lights. That’s all for now!]]> 2016-11-07 21:44:43 UTC https://padlet.com/sn6997/pn7yoi6ow60k/wish/135951884 sn6997 https://padlet.com/sn6997/pn7yoi6ow60k/wish/135952075 There are a few dwarf planets in our solar system.
