Energy created from the fusion reactions in the core contain a large amount of gamma rays which pass through the dense Radiative zone.]]> 2018-12-31 03:30:38 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907533 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907586 The convective zone makes up about 30% of the suns interior. It is a cooler region that surrounds the radiative zone. Here the energy is transported to the surface of the sun by convection currents.]]> 2018-12-31 03:32:47 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907586 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907648 Photosphere means “sphere of light”. It is the lowest level of the sun’s atmosphere and is the visible surface of the sun seen from Earth. The surface of the photosphere is covered with a pattern of bright grainy marking called granulations. These grainy markings are the result of convection currents that bring hot gases up from the interior.]]> 2018-12-31 03:34:32 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907648 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907742 Chromosphere means sphere of color. This layer of the sun's atmosphere extending to about 2500 km above the photosphere. It is visible during a total solar eclipse. ]]> 2018-12-31 03:37:34 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907742 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907884 The corona extends hundreds of thousands of miles into space and consists of plasma. The corona is much hotter than the surface of the sun. ]]> 2018-12-31 03:41:04 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316907884 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908373 Sunspots appear on the photosphere as dark patches. Sunspots are areas where strong magnetic fields interfere with the normal convection currents which bring the energy to the surface. Sunspots appear in pairs or groups of pairs with opposite magnetic polarity. ]]> 2018-12-31 03:55:49 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908373 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908435 Prominences are huge clouds of ejected gases which rise thousands of kilometers above the photosphere and orient themselves along the magnetic fields associated with sunspot pairs. Prominences can last for many weeks or even months if they form at boundaries between large scale magnetic fields.]]> 2018-12-31 03:57:05 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908435 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908486 A solar flare is a sudden and violent discharge of energy in the chromosphere associated with sunspots. The flares usually form rapidly and can last for anytime between a few minutes to a few hours. They release a huge amount of energy and shoot out energetic charged particles into space]]> 2018-12-31 03:58:42 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908486 20awiencek https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908587 The sun sends us more than heat and light; it sends lots of other energy and small particles our way. The protective magnetic field around Earth shields us from most of the energy and particles, and we don’t even notice them.]]> 2018-12-31 04:01:26 UTC https://padlet.com/20awiencek/ml8dx76xptvw/wish/316908587
