- Q1The points labeled on the chart represent the approximate size of Earth, the Milky Way, the Moon, and the Sun. The approximate size of the Solar System is also shown. Which point on the chart best represents the approximate size of the Sun?WXZY120s
- Q2The points labeled on the chart represent the approximate size of Earth, the Milky Way, the Moon, and the Sun. The approximate size of the Solar System is also shown. Which celestial body is represented by by letter X?Milky WaySunMoonEarth120s
- Q3The sun is much larger than the moon. However, as viewed from Earth, the sun and moon appear to be the same size. Why do the sun and moon appear to be the same size when viewed from Earth?The moon is much denser than the sun.The moon is much hotter than the sun.The moon is much closer to Earth than the sun.The moon is much brighter than the sun.120s
- Q4In 1995, the Hubble Space Telescope photographed a tiny spot in the sky for a period of ten days; 342 exposures were placed together to create an image known as the Hubble Deep Field. Although the sample is tiny, it is representative of the universe, which looks similar in all directions. The image below shows a collection of billions of stars. The Hubble Deep Field shows at least 3,000 groups of these stars. Which term describes this group of stars?GalaxyMoonSolar systemUniverse120s
- Q5Which one of the following planets is the LESS DENSE planet of the list?EarthVenusSaturnMercury120s
- Q6The diagram represents the layers of the Earth (core, mantle and crust). Which one of the following planets would you expect to have the same structure and layers?NeptuneJupiterMarsUranus120s
- Q7Which statement is true regarding measuring distances in space?All of the terrestrial planets are more than one astronomical unit (AU) from the Sun.An astronomical unit (AU) is larger than a light year.The Earth is one astronomical unit (AU) from the Sun.The time taken for light to travel through our Solar System is longer than that for light to travel through the Milky Way.120s
- Q8Jill is creating a scale model of the Solar System. She uses a basketball to represent the Sun. Which of the following should she use to most accurately represent the size of Earth?Ping pong ballMarbleGrain of sandTennis ball120s
- Q9Our solar system consists of eight planets. Each planet is classified as either a terrestrial planet or a gas giant planet. Which is a difference between these two types of planets?Gas giant planets have rockier crusts than terrestrial planets.Gas giant planets are denser than terrestrial planets.Terrestrial planets are larger than gas giant planets.Terrestrial planets have thinner atmospheres than gas giant planets.120s
- Q10Space exploration has advanced our knowledge of the universe. Which space journey would take the longest?A journey from Earth to the moonA journey from Earth to the sunA journey from Earth to a star in the constellation CentaurusA journey from Earth to the farthest planet in our solar system120s
- Q11The surface of Mercury has many more craters than the surface of Earth has. Which of the following statements best explains why Mercury has many more craters than Earth has?Mercury has a smaller mass than Earth has.Mercury is much closer to the Sun than Earth is.Mercury has a thinner atmosphere than Earth has.Mercury rotates faster than Earth does.120s
- Q12Which of those objects has the greatest gravitational force?EarthJupiterAsteroidsMoon120s
- Q13Saturn is 9.5 astronomical units (AU) from the Sun and Mars is only 1.5 AU from the Sun. Saturn is also much larger than Mars. Based on this information, how does the average surface temperature on Mars compare to the average surface temperature on Saturn?Since Mars is closer to the Sun than Saturn, it has a higher average surface temperature.Saturn is larger than Mars and absorbs more light, so it has a higher average surface temperature.Even though Saturn is further away, Saturn's rings cause it to have a lower average surface temperature.Since both planets are more than 1 AU from the Sun, their average surface temperatures are equal.120s
- Q14According to the data table, how many times is Jupiter farther away from the Sun that the Earth?about 10 timesabout 30 timesabout 20 timesabout 5 times120s
- Q15The current model of our Solar System is called the heliocentric model, which means the Sun is at the center. Before scientists developed the current model, which is best supported by the evidence, what was believed to be the center of our solar system?The Solar System had no center because all the planets' orbits were random.A star other than the Sun was the center of the Solar System.Earth was the center of the Solar System.A black hole was the center of the Solar System.120s
