2. What is the main cause of air movement around the Earth.
Answer

3. Differences in temperature
Home

4. The Coriolis Effect is when winds curve instead of moving in straight lines. What causes this to happen?
Answer

5. The rotation of Earth on its axis.
Home

6. What do cooler temperatures do to the air to cause wind?
Answer

7. Cooler air is more dense and sinks, warm air moves in above the cool air.

8. What commonly causes ocean breezes on the coast?
Answer

9. When the water and land is heated at different speeds

16. What will form when a large low-pressure air mass meets a large high-pressure air mass?
Answer

17. A front will form
Home

18. What are the properties that describe a cold air mass?
Answer

19. High pressure and high density
Home

20. What do we call the measure of the amount of water vapor in the air?
Answer

21. humidity .
Home

22. A rapidly rotating cloud that forms over land and causes destruction over a multi state area.
Answer

23. tornado
Home

24. Which storm is longer lived, larger in size and generates more rainfall: tornadoes or hurricanes?
Answer

25. Hurricanes
Home

26. Why do hurricanes lose energy when they travel on land for a few days?
Answer

27. The air above the land is dry and cooler than the ocean where it forms.
Home

28. Why don’t hurricanes form near the cold dry air of the polar climate zone?
Answer

29. Hurricanes need warm and moist air that is found at the equator.
Home

30. What causes hurricanes to move to the east after moving onto land for several days?
Answer

31. Global winds or Coriolis effect
Home

32. Why do coastal towns have a smaller temperature range from coldest to warmest of the year?
Answer

33. The temperature of the coastal towns is influenced by the slow changing ocean temperatures.
Home

34. The change in temperature and humidity of a small area over a few days is called..
Answer

35. weather
Home

36. The average temperatures and humidity levels of a large area over time, that is influenced by its closeness to oceans and distance from the equator or poles.
Answer

37. climate
Home

38. What causes the temperatures at the equator to stay nearly the same all year?
Answer

39. The sun’s angle stays directly overhead all year at the equator.

40. An air mass that blows down to the United States from Canada would have which name:
Maritime tropical
Continental polar
Continental tropical
Answer

41. continental Polar cP
Home

42. Where does the energy come from that causes weather on our planet?
Answer

43. The Sun
Home

44. What type of thermal energy transfer best describes how the surface of the Earth is heated by the Sun?
Answer

45. radiation
Home

46. What causes high tide and low tide in the Earth’s oceans?
Answer

47. The pull of the moon’s gravity
Home

48. What characteristic of Earth is responsible for the seasons?
Answer

49. the tilt of its axis
Home

50. How does the tilt of the Earth’s axis affect differences in daylight and weather at the poles?
Answer

51. Since the Earth’s axis is tilted, the poles are farther away from the sun in winter and the light is spread out over the land, closer to the sun in summer, more daylight.
