- Q11An astronomer uses a telescope to observe a star. She observes that the color of this star is similar to the color of the Sun. Therefore, she infers that the star and the sun have similar sizes and surface temperatures. Using this information, what can the astronomer conclude about the star?The star is medium sizedThe star is a white dwarfThe star is hotter than most other stars in our galaxyThe star is brighter than most other stars in our galaxy.60s
- Q12Our 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.Terrestrial planets are larger than gas giant planetsTerrestrial planets have thinner atmospheres than gas giant planetsGas giant planets are denser than terrestrial planets60s
