Turn in your abstinence form to front 2 Turn in your abstinence form to front 2. Which of the following best explains how scientist 1’s view differs from scientist 2’s view? A. Scientist 1 explains how bowl-shaped craters are formed and Scientist 2 does not. B. Scientist 1 explains how flat-bottomed craters are formed and Scientist 2 does not. C. Scientist 2 explains how central peaks are formed and Scientist 1 does not. D. Scientist 2 explains how gravity affects crater shape and Scientist 1 does not.

3. In which of the following ways, if they were possible, could scientist 1 best test the relationship between gravity and crater shape? A. Creating artificial craters in a lab using different materials. B. Creating artificial craters on 2 planets having the same gravity. C. Creating artificial craters on 2 planets having different gravity. D. Creating artificial craters in 1 location on Earth.

4. Which of the following factors was controlled by Scientist 2 when metal balls were used to create craters in sand and rock? A. The speed of the metal ball B. The diameter of the crater formed on impact C. The depth of the crater formed on impact D. The shape of the crater formed on impact

5.Which of the following assumptions about sand and rock was made by scientist 2? A. Sand and rock are the only materials which craters can form B. Sand and rock vaporize when hit with a meteor C. Sand and rock are found on all planets D. Sand and rock are similar to materials found on other planets
