The diagram above shows a vertical section of a hillside. Which of the formations in the hillside is the youngest? sandstone formation igneous formation limestone formation shale formation

2 2. Image courtesy of Galileo Project, JPL, and NASA The image above was taken by the Galileo spacecraft as it visited the asteroid belt on its way to Jupiter. Shown in the image are two rocky-iron bodies. The large object on the left is an asteroid named Ida. The object on the right, which measures only about 1 mile across, is named Dactyl. Dactyl is a tiny moon that orbits the asteroid Ida. Dactyl orbits Ida due to small differences in the objects' rocky-iron compositions. electrical energy transferred between the two objects. the mutual gravitational attraction between the two objects. the magnetic force field that defines the asteroid belt. 3. The movement of Earth's tectonic plates is related to phases of the Earth's Moon. movements of materials in the mantle. cycles of sunspots. seasonal changes in weather systems. 4. Which of the following correctly shows layers of the Earth in order from outside to inside? Outer Core Inner Core Crust Upper Mantle Lower Mantle Upper Mantle Lower Mantle Inner Core Outer Core Crust Crust Upper Mantle Lower Mantle Outer Core Inner Core Crust Upper Mantle Lower Mantle Inner Core Outer Core

3 5. At noon on Saturday, Rob pulled a carton of ice cream from his 30 F freezer and set it on his kitchen table where the temperature was 75 F. He put a thermometer into the ice cream and and observed the change in temperature. Every time the temperature of the ice cream rose 3 degrees, he wrote down the time. Which of the following questions was Rob MOST LIKELY trying to investigate? How fast does ice cream go from freezer-temperature to room-temperature? How much ice cream melts every 10 minutes? Is ice cream heavier when it is frozen or when it is melted? How long can I sit and watch ice cream melt? 6. Which of the following is an example of potential energy? I. light energy II. electromagnetic energy III. energy due to the arrangement of atoms within substances IV. energy in a stretched rubber band V. energy an object has due to its height III, IV, and V only I and IV only V only II, III, and V only

4 7. What force MOST LIKELY had the greatest effect in creating this sea arch? sun exposure wave erosion rain erosion human digging 8. Fossils similar to marine life found in the oceans today have been found in rocks on top of mountains. How can this be explained? Marine organisms have evolved from land organisms. Marine organisms were once able to breathe air. The rocks in which the fossils were found were formed under an ocean. The marine life can live on land or sea. 9. Robbie is trying to learn as much as he can about a rock that he found. This particular rock contains some fossils. What can Robbie learn from the fossils? the mass of the rock whether the rock is a compound or an element whether or not the rock can float the relative age of the rock

5 10. Which of the following statements is true about evolution and diversity among organisms? Only a change in a species' environment can cause the evolution of that species. Both genetic variation and environmental factors can cause evolution and diversity of organisms. Individual organisms can evolve to have new traits over time, but those traits will not be transferred to their offspring. Only unicellular or simple multicellular organisms can evolve and become more diverse. 11. Which of the following is true about the locations of earthquakes, volcanoes, and tectonic plate boundaries? Earthquakes and volcanoes are both commonly located near plate boundaries. Volcanoes are commonly located near plate boundaries, but earthquakes are not. Neither earthquakes nor volcanoes are located near plate boundaries. Earthquakes are commonly located near plate boundaries, but volcanoes are not. 12. The weathering of a tall mountain down into a low-lying hill is an example of a landform being changed through a process. The buildup of sand dunes by the deposition of sediment is an example of landforms being created through a process. destructive; destructive constructive; constructive constructive; destructive destructive; constructive
