Name: ___________________________________ Page ______ Protostar Use the following words to fill in the blanks: Cloud, Gravity, Heat, Hydrogen, Nebula, Nuclear Fusion and Shine gravity cloud Within a ____________________, ____________________ pulls ____________________ into a hydrogen spinning ____________________, heating up enough to begin _________________________. nuclear fusion nebula Great amounts of ____________________ are given off and the new star begins to ________. heat shine Medium Mass Star Use the following words to fill in the blanks: Carbon, Cool, Core, Dies, Fusion, Helium, Helium, Hydrogen, Red and White Dwarf hydrogen helium After most of the ____________________ changes to ____________________, the core ____________________begins to shrink, the outer shell expands, begins to cool Helium ____________________ and becomes ____________________. ____________________ in red carbon fusion the core now becomes ____________________. With no more ____________________ the star slowly ____________________ and becomes a _________________________________. white dwarf dies White Dwarf Use the following words to fill in the blanks: Black Dwarf, Cool, Dead Star, Glowing, Gravity, Mass, Matter, Pounds and Teaspoon, Gravity matter ____________________ has pushed ____________________ together into such a small, mass dense area that a ____________________ full may have the ____________________ of many teaspoon pounds 1000’s of ____________________. The star cool shines with a ____________________ white light and eventually stops glowing dead star ____________________, becoming a ____________________________________ called a ____________________________________. black dwarf Name: ___________________________________ Page ______ Massive Star Use the following words to fill in the blanks: Carbon, Core, Cycle, Energy, Heat, Iron, Nebula and Supernova cycle It follows the same ____________________ as a medium mass star until the core carbon ____________________ becomes ____________________. Then Carbon becomes other iron elements and produces an ____________________ core which releases tremendous energy supernova ____________________ and explodes as a ____________________. With added heat ____________________ the Iron forms other elements which explode into space causing new nebula ____________________ to form again. Neutron Star Use the following words to fill in the blanks: Core, Energy, Radio Waves, Spins and Supernova supernova core It is the ____________________ left after a ____________________ of a massive star. It spins energy ____________________ rapidly giving off ____________________ in the form of radiowaves ________________________________________ and is very dense. Black Hole Use the following words to fill in the blanks: Core, Gravity, Light, Matter, Pulled In, Super-massive and Supernova, core super-massive It is the ____________________ of a ____________________ star after a supernova matter ____________________ has occurred. It is so dense any ____________________ and pulled in light ____________________ nearby is ____________________ by its own _________________. gravity
