2. 5. Why would you expect to find more metal in Earth's liquid core than in Earth's solid crust? A. Metals are dense, and the densest materials sink toward Earth's core. B. Metals are formed by the high temperature and pressure in Earth's core. C. Earth's core is hotter than the crust, and only metal can exist at high temperatures. D. Earth's crust is cooler than the core, so many solids other than metals can be found in the crust

3. 9. The Pacific Ring of Fire is a chain of volcanoes around the Pacific Ocean. What created this pattern of volcanic activity? A. oceanic plates colliding and sliding past each other B. continental plates colliding and sliding past each other C. oceanic plates colliding and subducting under continental plates D. continental plates colliding and subducting under continental plates

4. 24. Which of these situations causes convection in Earth's mantle? A. the downward force of air pressure at Earth's surface B. the movement of seismic waves through Earth's interior C. the movement of materials across Earth's surface caused by erosion D. the difference in temperatures between Earth's hot interior and cooler surface

5. 25. Charlie is collecting data about boiling water. He puts very cold water on a burner and observes the temperature at which it begins to boil. He records it as 100 degrees Celsius. He does the same with cool water, warm water, and hot water. Each time, the water boils at 100 degrees Celsius. Which statement is the BEST conclusion for this experiment? A. The boiling point of water is constant at 100 degrees Celsius. B. Hot water boils more quickly than cold water. C. The boiling point of water depends on the temperature it started out at. D. All boiling points are 100 degrees Celsius.

6. 27. A mid-ocean ridge is evidence of the theory of plate tectonics because A. plate tectonic boundaries do not occur at midocean ridges B. crust is neither created nor destroyed at a midocean ridge C. old crust is destroyed as the plates come together D. new crust is created as the plates separate.

7. 1. Students were investigating how the mass of different objects relates to the distance traveled when thrown through the air. Which protective equipment is MOST important for the students to wear during this investigation? • A. short sleeves • B. lab coat • C. ear plugs • D. eye goggles

8. 4. Why is the rock of the sea floor along a mid-ocean ridge warmer than the rock of the sea floor that is farther away? A. Friction from earthquakes along a mid-ocean ridge heats the rock around the ridge. B. Rock from the sea floor near a mid-ocean ridge is warmer because it has more sediment covering it. C. A mid-ocean ridge is taller than the surrounding sea floor; therefore, it gets more energy from the Sun. D. Convection currents rise in the mantle along the mid-ocean ridge, transporting heat from Earth’s interior.

9. 3. Which characteristic is shared by BOTH earthquakes and volcanic eruptions? • Both can cause lava flows. B. Both can cause global climate changes. C. Both are caused by movements of tectonic plates. D. Both are caused by material rising from Earth's core to the surface.

10. 4. The same plant and animal fossils are found across four different continents. This supports the theory that A. climate in those areas were not the same B. the meteor that destroyed the dinosaurs also destroyed some plants C. plants lived at the same time as dinosaurs D. the continents were once parts of one large supercontinent.

11. 5. A forested area was cleared to build a new mall and parking lot. Aisha wondered if this changed the weather in that area. Which of these questions should Aisha ask to investigate the situation? A. What are the types of stores in the mall? B. How many people used the land after the mall was built? C. How many different species used the area before and after the mall was built? D. What was the average temperature of the area before construction and after the mall was built?

12. 6. Which of these is the BEST reason for scientists to publish their findings, discoveries, and theories? A. so that the past theories are proven wrong B. to be recognized as professionals by other scientists C. so that the information can be shared and used by all D. so that no other scientist can replicate their discoveries

13. 7. Which of these statements BEST explains the discovery of the same types of rocks in South America and Africa? A. South America and Africa are similar in shape. B. South America and Africa were once connected. C. Rocks in South America and Africa are similar only by accident. D. Rocks in South America and Africa have eroded in similar ways.

14. 8. Why is an apple often used as a model of the Earth? A. The parts of an apple can be used as examples of the different layers of the Earth. For example, the skin or peel of the apple represents the Earth’s crust. B. The apple is solid all the way to its core, just like the Earth. C. An apple has seeds inside, which represent the liquid parts of the solid mantle of the Earth. D. The center of an apple is very light and spread out, just as the center of the Earth is also very light and thinly concentrated.

15. 9. Evidence that environmental conditions on Earth have changed over time would be finding a fossil of a A. tropical plant in Antarctica. B. tropical plant in South America. C. clam in the Pacific Ocean. D. clam in the Atlantic Ocean.

16. 10. The same plant fossil is found across four different continents. This supports the idea that A. at one time the earth only had one climate B. all these continents once fit together and had the same climate C. the seeds of this plant can travel across the ocean between the continents D. this plant can grow in all climate zones across the Earth.

17. 11. Which is NOT evidence of plate tectonics? A. the location of earthquakes and volcanoes B. the way the continents fit together like a puzzle C. where certain fossils and rock types are found D. how fast earthquakes travel through Earth's crust

18. 12. South America and Africa were once part of the same landmass. What piece of evidence does NOT support that location? A. The Sahara desert in northern Africa was created when the Amazon River in South America broke away B. Similar rock types are found along the coasts of both continents C. The same fossil plants are found across the southern end of South America and across the middle of Africa. D. The same dinosaur fossils at the tip of South America and the tip of Africa.
