The cycle repeating. The Sun heats Earth's surface. The air rising and sinking. The air above Earth's surface is warmed. 4 / 15 The direction of global winds turning towards or away from the equator is caused by Earth's .................. gravity revolution atmosphere rotation 5 / 15 Changes in air pressure create winds gravity condensation temperature 6 / 15 What does symbol # 1 mean? cold front warm front occluded front stationary front 7 / 15 When a warm front occurs, what type of weather does it bring? warm and clear clouds and long rains hail thunderstorms 8 / 15 When two different air masses collide... A new planet evolves Dinosaurs become extinct A front forms They casually become one 9 / 15 Trade winds blow across Earth from the .................. , while westerlies blow from the ............... south - north west - east north - south east - west 10 / 15 An air mass has similar .................. temperature and moisture cold and wind warm and dry rain and temperature 11 / 15 Which of the following statements best explain how global winds are different than local winds? Local winds are created by Earth's rotation, and global winds occur when air flows from a high-pressure area to a low-pressure area. Both global winds and local winds are created by Earth's rotation and shape. Global winds are stronger. Global winds are created by Earth's rotation and shape, and local winds occur when air flows from a high-pressure area to a low-pressure area. Global winds occur because of convection and local winds occur because of condensation. 12 / 15 What is the name this front? occluded front warm front cold front stationary front 13 / 15 What can you infer about wind from the map below? All of the winds flow toward the Equator. The two westerlies, Northeasterly and Southeasterly, flow in opposite directions. The westerlies flow from the west to the east. The southeasterly winds flow north of the Equator. 14 / 15 Which of the following statements are needed for convection to occur? Hot air rises Hot air sinks Wind blows Sun to heat Earth's surface 15 / 15 How does the Earth's rotation affect trade winds? It causes them to turn towards the Equator. It causes them to turn towards the Poles. It causes them to behave like westerlies. It causes them to behave like Polar easterlies. Your score is 0% Restart quiz Go to the Quizzes Page
