- Q1The table shows the distance between Earth and seven relatively nearby stars in the galaxy. According to the table, the Sun is -hundreds of thousands of times closer to Earth than any of the other stars.millions of times closer to Earth than any of the other stars.thousands of times farther from Earth than any of the other stars.about as close to Earth as the other stars.120s
- Q2The table displays information about several galaxies. The table indicates that the Sun is located in-a ring galaxy.an elliptical galaxy.an irregular galaxy.a disc-shaped galaxy120s
- Q3An image of the Milky Way galaxy is shown below. The Milky Way was created when a cloud of gas and dust began to condense. Near the center of the Milky Way, material is just beginning to condense into new stars. This indicates that the Sun is-at the center of the Milky Way galaxy, close to dust and gas that has not yet condensed into new stars.near the center of the Milky Way galaxy, close to other stars that are just beginning to form.outside the Milky Way galaxy, close to other stars that are traveling through space.near the edge of the Milky Way galaxy, close to other stars that have already formed.120s
- Q4Beta Ursae Majoris, one of the stars in the constellation called the Big Dipper, is slightly hotter and larger than the Sun. Beta Ursae Majoris is a main sequence star. This indicates that the Sun is-a medium-sized star.also in the Big Dipper constellation.an extremely small star.an extremely large star.120s
- Q5**USE H-R DIAGRAM FOR QUESTIONS 5, 6, 7, 8, 9** The H-R diagram below displays the temperature and magnitude of thousands of stars in the galaxy. Use the diagram and your knowledge of science to answer any questions that follow. The star Arcturus is classified as a giant star. Which of the following best describes Arcturus?Brighter than most supergiant stars and has a relatively high temperature.Brighter than most main sequence stars but has a relatively low temperature.Dimmer than most main sequence stars has a relatively low temperature.Dimmer than most supergiant stars but has a relatively high temperature.120s
- Q6The Sun is classified as a "G" main sequence star. The H-R diagram indicates that because the Sun is a "G" main sequence star, it is a-large star, larger than a supergiant.medium-sized star, smaller than a giant and larger than a white dwarf.small star, smaller than a white dwarflarge star, smaller than a supergiant and larger than a giant.120s
- Q7An astronomer detects a star with a temperature of about 3,000 Kelvin (K) and a luminosity of about 10,000 solar units. Based on the H-R diagram, what type of star has the astronomer detected?A white dwarfA giantA main sequence starA supergiant120s
- Q8The Sun is classified as a yellow dwarf, which is a star in the main sequence of the H-R diagram. This reveals that the Sun is-a small stara large stara medium-sized staran extremely large star120s
- Q9An astronomer detects a star with a temperature of about 15,000 Kelvin (K) and a luminosity of about 1.0 solar units. Based on the H-R diagram, what type of star has the astronomer detected?A white dwarfA giantA supergiantA main sequence star120s
- Q10The star 40 Eridani B was the first white dwarf ever discovered. Which of the following best describes 40 Eridani B?Very bright with a relatively low temperatureVery bright with a relatively high temperatureDim with a relatively high temperatureDim with a relatively low temperature120s
- Q11Which one of the following is NOT true of stars?Stars generate radiant energy from a fusion reaction at the nuclear level.Stars are primarily made of hydrogen and helium.Stars have smaller masses than planets.Stars have a larger gravitational force than planets.120s
- Q12The table below shows the distance between Earth and the Sun, as well as the distance between Earth and all of the stars in the Big Dipper constellation. The data in the table show that the stars in the Big Dipper are-thousands of times closer to Earth than the Sun.almost as close to Earth as the Sun.millions of times farther from Earth than the Sun.billions of times farther from Earth than the Sun.120s
- Q13Which statement about the universe is correct?It is gradually getting smaller.It consists of one Sun, nine planets, and satellites.It is made up mostly of empty space.It is known as the Milky Way.120s
- Q14Directions: The satellite photograph below depicts the Milky Way galaxy. Use the photograph and your knowledge of science to answer any questions that follow. The Sun is located-at the exact center of this galaxy.near the center of this galaxy.near the edge of this galaxy.outside of this galaxy.120s
- Q15In the center of the Milky Way is a large bulge of stars. Within this bulge lies a black hole. The Sun is locatedoutside of the Milky Way.in the black hole in the center of the Milky Way.in the large bulge of stars near the center of the Milky Way.near the edge of the Milky Way.120s
