17. Oceans/Weather $100 How is the west coast of Australia affected by surface currents? • Warmer because the surface current comes from the warm equator • Cooler because the surface current comes from the cool equator • Warmer because the surface current comes from the warm Poles • Cooler because the surface current comes from the cool Poles

18. Oceans/Weather $2000 How do the oceans affect the global climate? • The ocean keeps the planet’s temperature cooler than it would otherwise be • The ocean keeps the planet’s overall temperature moderate, not too hot and not too cold • The ocean keeps the atmosphere’s winds faster than they would otherwise be • The ocean keeps the atmosphere’s winds slower than they would otherwise be

19. Oceans/Weather $300 Sea breezes blow from the ocean toward the shore because ___ • The sun heats up the water more quickly than the land • The sun heats up the land more quickly than the water • Ocean currents cause the wind to blow toward shore • Breezes are created as Earth rotates on its axis

20. Oceans/Weather $400 Why do hurricanes typically form off the coast of Africa? • The water temperature is cold • The winds are stronger near africa • There is a narrow channel between two large island chains • The water temperature is warm

21. Oceans/Weather $500 According to the map, where are thunderstorms most likely to occur? • In Seattle, because a cold front has moved through • In Chicago, because a cold front is approaching • In Boston, because a cold front is to the west of the city • In San Diego, because it is on the edge of a warm front

27. Ecology $100 Ticks are frequently found on animals such as deer. The ticks burrow into the skin and suck blood from the animal. The relationship between the tick and the deer is an example of ___ • Predation because the deer is the predator and the tick is its prey • Mutualism because both the deer and the tick benefit, and neither organism is harmed • Commensalism because the tick removes blood from the deer but does not harm the deer • Parasitism because the tick is a parasite, which harms its host, the deer

28. Ecology $200 Artificial reefs, such as old ships placed in the ocean by humans, affect the ecosystems of the ocean. How can these artificial reefs alter the ecosystem? • Artificial reefs provide more oxygen to organisms • Artificial reefs provide a new habitat for organisms • Artificial reefs provide less protection to small fish • Artificial reefs provide additional locations to drill for oil
