PPT-The Life Cycles of Stars

PowerPoint Created by Alexander J Hawkins Information documented from DK Smithsonian UNIVERSE Definitive Visual Guide Stellar Life As human beings go through cyclic lives maturing from birth to maturity to old age stars also follow a series of stages from their creation until death Stars follow varying sequences of change depending greatly on their solar mass or their gravitational weight .

What do you notice by looking at this image? . From the picture you should have noticed that stars have _______________.The different colors indicate the __________________ of a star.. How do stars work and evolve?. Why do stars shine?. Nuclear reactions. Fusion and fission reactions. How nuclear reactions can create energy. Why is it hard to get fusion nuclear reactions to occur?. Stars form in a cloud of dust and gas in space called a nebula.. How do stars form?. A force from outside the nebula causes the cloud to condense into stars. . Example: a shockwave. Gravity causes the particle in the cloud to contract..
