1. As mentioned in an earlier of this project, occasionally an asteroid fragment makes its way to Eartths the fragment falls through the atmosphere, it is heated and some of the material is vaporized. a. (3 points) Explain how you could determine the composition of this hot vaporized material from the light it emits. b. (3 points) Provide an example of how this type analysis is used during the testing of soil, water, oil, or air samples. Provides reference to the source of your information and reasons why it should be considered a reliable source. (Note: this Checklist to Evaluating Web Sites may be helpful in evaluating your source of information.) 2. Some asteroid fragments end up on the surface of Earth. Such fragments could be radioactive. b a. (1 point) What is the chief cause of radioactivity? in. (1 point) List and describe the three different types of radioactivity. c. (3 points) Suppose that you had a radiation detector that could not the identify the type of radiation being emitted from a fragment sample. What eise could you. use, in conjunction with the detector, to determine the type of radiation being emitted? 7 _ Explain
