Arrange layers of sun from Core to outermost layer. Row 1, Col 1 (Luminosity) A H-R diagram is a graph of Stars temperature and 1,2 (white dwarf) A low mass main sequence star will eventually evolve into a 1,3 (Main Sequence) More than 90% of stars are found on this part of H-R diagram 1,4 (Nebula) Enormous clouds of gas and Dust where stars are born 2,1 (Light Year) Unit used to measure distance to Stars: 2,2 (When Nuclear fusion starts) At what point of evolution Is the star actually born? 2,3 (Low mass as they use their fuel slowly) Which stars have longer lifetime Low mass or high mass? 2,4 (They produce light from Nuclear fusion You can see stars at night because 3,1 (Hydrogen) The most common element In most stars 3,2 (Mass) The main factor that affects the evolution of a star is its 3,3 (Protostar, main-sequence star, red giant, white dwarf) Give correct order of Evolution of sun-like star From young to old: 3,4 (Gravity) What force pulled matter together in the solar nebula to form Solar system? 4,1 (Color, temperature,Size, brightness) Name four characteristics Used to classify stars 4,2 (Blue Rigel)) Which star has hotter surface Red Aldebaran or blue Rigel 4,3 (Core) The part of sun where nuclear Fusion occurs: 4,4 (Photosphere) The layer of sun that gives off visible light 5,1 (Iron) Fusion reactions that combine light elements release energy Only until what element is Created? 5,2 (Binary system.) A system of two stars tied Together by gravity and Orbiting Each other is called : 5,3 (1/25) If star is 5 times farther away than another star with same Luminosity, how will Brightness compare? 5,4
