- Q2Town X is in a coastal area near the equator. How does the ocean impact the climate of town X?Town X will experience great extremes in weather because of the temperatures at day and night.Town X will experience more tropical storms than inland towns.Town X will have large amounts of snow due to increased condensation over the ocean.30s

- Q4An incomplete model of the water cycle is shown. Which feature could be added to represent evaporation?a garden showing plants releasing water vapor into the aira small stream of water flowing downward at an anglea small, drying puddle as the sun heats the water and changes it to water vapor30s
- Q5What effect does the oceanic current east of Brazil have?Heat flows from B to A. Weather and climate in the region around A are unusually warm in the summer.Warm water flows from B to A. Weather and climate in the region around B are unusually warm in the summer.Cool water flows from B to A. Weather and climate in the region around A are unusually cool throughout the year.30s
- Q6Jill used an aquarium filled with salt water to make a model of ocean currents. Which component should Jill add to the model to help demonstrate a major factor in global ocean currents?algae to show how photosynthesis causes changes in water densityfresh water mixed with food coloring to show differences in densitysaltwater fish to show how the movement of animals causes movement of watera spray bottle of salt water mixed with food coloring to show how rain causes movement of water30s
- Q7Which model shows how convention currents occur?Model BModel AModel CModel D30s
- Q8Figure 1 shows a current of water in the North Atlantic Ocean. Figure 2 shows a pot of water heated on a stove. Which two statements correctly compare these processes? [A) Convention is occurring in both figures. B) The movement of water is driven by heat in both figures. C) Water is heated from the deepest part of the water in both figures. D) No current forms in Figure 2 because it lacks room for the cycle to continue.]A and ED and EB and DA and B30s
