Reviewing Main Ideas 1 Stars Constellations are patterns of stars in the night sky. Some constellations can be seen all year. Other constellations are visible only during certain season. Parallax is the apparent shift in the position of an object when viewed from two different positions. Parallax is used to find the distance to nearby stars.
37
The Sun 2 The Sun is the closest star to Earth.
Reviewing Main Ideas 2 The Sun The Sun is the closest star to Earth. Sunspots are areas on the Sun's surface that are cooler and less bright than surrounding areas.
38
Reviewing Main Ideas 3 Evolution of Stars Stars are classified according to their position on the H-R diagram. Low-mass stars end their lives as white dwarfs. High-mass stars become neutron stars or black holes.
39
Galaxies and the Universe
Reviewing Main Ideas 4 Galaxies and the Universe A galaxy consists of stars, gas, and dust held together by gravity. Earth's solar system is in the Milky Way, a spiral galaxy. The universe is expanding. Scientists don't know whether the universe will expand forever or contract to a single point.

Question 1 Answer Why do constellations appear to move?
Chapter Review Question 1 Why do constellations appear to move? Answer Constellations appear to move because Earth is moving. As Earth rotates on its axis, stars appear to complete a circle in the sky. PS 1.1c
41
Chapter Review Question 2 Distances between stars and galaxies are measured in __________. A. astronomical units B. light-years C. red shifts D. spectral lines PS 1.1b
42
Chapter Review Answer The answer is B. A light-year is the distance that light travels in one year, about 9.5 trillion km.
43
Chapter Review Question 3 Sudden violent eruptions from the Sun’s surface are called __________. A. prominences B. solar flares C. solar winds D. sunspots PS 1.1a
44
Chapter Review Answer The answer is B. Solar flares occur when gases near a sunspot brighten suddenly and shoot outward at high speed.
45
Question 4 The closer the star, the greater the __________.
Chapter Review Question 4 The closer the star, the greater the __________. A. absolute magnitude B. blue shift C. parallax D. red shift PS 1.1h
46
Chapter Review Answer The answer is C. The nearer an object is to the observer, the greater its parallax is.
47
Question 5 Fusion of hydrogen in a star’s core forms _________.
Chapter Review Question 5 Fusion of hydrogen in a star’s core forms _________. A. carbon B. helium C. oxygen D. water PS 1.1e
48
Chapter Review Answer The answer is B. Temperatures must be high to cause the hydrogen atoms to fuse.

Question 2 Use the diagram to determine which of the following statements is true. PS 1.1h
52
Standardized Test Practice
A. Star A must be closest because it has a larger parallax than Star B. B. Star A must be farther because it has a larger parallax than Star B. PS 1.1h
53
Standardized Test Practice
C. Star B must be closest because it has a larger parallax than Star A. D. Star B must be farther because it has a larger parallax than Star A. PS 1.1h
54
Standardized Test Practice
Answer The answer is C. The nearer an object is to the observer, the greater its parallax. Star B has a large parallax.
