WebAll stars will expand, cool and change colour to become a red giant. What happens next depends on how massive the star is. A smaller star, like the Sun, will gradually cool down … WebEarth Sciences questions and answers. The diagrams below show the interior structure of a star of the same spectral type as the Sun at four different stages of evolution, labeled stages A through D. The stages are shown in chronological order, and the stars are not drawn to scale. Use these diagrams to answer the questions on the following pages. helmet bluetooth communication

The formation and life cycle of stars - BBC Bitesize

WebFigure 18.15 is a schematic H–R diagram for a large sample of stars, drawn to make the different types more apparent. ... They are the later stages in a star’s life. As a star consumes its nuclear fuel, its source of energy changes, as do its chemical composition and interior structure. These changes cause the star to alter its luminosity ... WebAs a star goes through the stages of its life, its luminosity and temperature change. Thus, its position on the H–R diagram, in which luminosity is plotted against temperature, also changes. As a star ages, we must replot it in different places on the diagram. WebA star passes through many different stages during its life. In this activity, you’ll use your knowledge and intuition to arrange a series of images that describes the life of a star … lake worth florida appliance repair
