To confirm the answers to the questions:
14. The statement says that the sun's layer is called the photosphere. To verify if this statement is true or false, you can do a quick search on the internet. A reliable source like NASA or the National Solar Observatory can provide accurate information about the layers of the sun. By searching for "layers of the sun," you will find that the photosphere is indeed the outermost layer of the sun. Therefore, the answer is A. true.
15. The statement suggests that meteoroids can form when comets break apart, creating dust clouds. To verify if this statement is true or false, you can again do a search on the internet. Look for reputable sources that explain the formation of meteoroids and the relationship with comets. The answer to this question is A. true because comets breaking apart and creating dust clouds can indeed lead to the formation of meteoroids.
16. The statement asserts that a star is born whenever a nebula expands. To confirm if this statement is true or false, you can search for information about star formation and the role of nebulae in the process. Trustworthy sources like NASA or reputable astrophysical institutions can provide the necessary information. The answer to this question is B. false. While nebulae are involved in the process of star formation, a nebula expanding is not the sole requirement for the birth of a star.
17. The statement states that a star system has at least three stars. To confirm if this statement is true or false, you can search for information about star systems and their composition. Reliable sources such as astronomical databases or scientific research papers can provide accurate details. The answer to this question is B. false. A star system can consist of just one star (as in the case of our Solar System) or multiple stars, but it does not necessarily have to have a minimum of three stars.
