  • 11. The term "trade" in trade winds originally meant:
    Path or track
    Movement
    Commerce
    Wind
  • 15. Why does the equator receive more heat than the poles?
    The poles are always in darkness
    he equator has more water bodies
    Sun rays hit the equator directly
    The Earth is closer to the sun at the equator
  • 14. What is the process called when warm air rises and cool air takes its place?
    Convection
    Radiation
    Evaporation
    Conduction
  • 30. What type of wind pattern exists between the equator and 30° latitudes?
    Westerlies
    Polar easterlies
    Trade winds
    Jet stream
  • What happens to air when it heats up at the equator?
    It stays the same
    It becomes denser and sinks
    It cools down
    It expands and rises
  • 12. At which angle do the sun’s rays hit the equator?
    60 degrees
    90 degrees
    45 degrees
    30 degrees
  • 2. What type of pressure exists at the equator?
    Equal pressure
    Low pressure
    No pressure
    High pressure
  • 10. Why do trade winds help ships travel across the Atlantic?
    They blow consistently in one direction
    They blow in the opposite direction of ocean currents
    They are very weak
    They only occur during certain seasons
  • 8. Where do trade winds blow from?
    East to west
    West to east
    North to south
    South to north
  • 7. Why are the winds between 30° N and the equator called “trade winds”?
    They blow from west to east
    They are weak winds
    They help in trade and transportation
    They are variable in direction
  • 5. In which direction do winds slant in the Southern Hemisphere due to the Coriolis effect?
    South
    Right
    Left
    North
  • 19. Which winds blow between 30° and 60° latitude in both hemispheres?
    Westerlies
    Polar easterlies
    Doldrums
    Trade winds
  • 9. What causes winds to blow from high pressure to low pressure areas?
    The Earth's rotation
    Gravity
    Temperature
    The pressure gradient
  • 21. What is the area around the equator with very little wind called?
    Jet stream
    Polar front
    Doldrums
    Trade winds
  • 26. What role did trade winds play in the Age of Sail?
    They caused shipwrecks
    They made travel difficult
    They slowed down ships
    They made it easier to cross the Atlantic
  • 18. What effect does the Earth's rotation have on global wind patterns?
    It causes them to curve
    It stops them completely
    It weakens them
    It causes them to blow straight
  • 6. What are the winds called that blow from east to west between 30° N and the equator?
    Westerlies
    Polar winds
    Monsoon winds
    Easterlies
  • 3. Which force causes the winds to slant due to the Earth’s rotation?
    Gravitational force
    Coriolis effect
    Pressure gradient force
    Frictional force
  • 20. Where do polar easterlies occur?
    Between 30° and 60° latitudes
    Between 60° and the poles
    At the equator
    In the tropics
  • 22. What happens to the air pressure at the equator when warm air rises?
    Air pressure fluctuates
    Air pressure stays the same
    Air pressure increases
    Air pressure decreases
  • 27. Which area receives the most direct sunlight?
    30° latitude
    60° latitude
    The poles
    The equator
  • 4. In which direction do winds slant in the Northern Hemisphere due to the Coriolis effect?
    Left
    East
    Right
    West
  • 29. Which of the following is NOT a characteristic of trade winds?
    They are consistent throughout the year
    They helped sailors navigate in the past
    They blow from east to west
    They are caused by ocean currents
  • 16. What are the winds called that blow from 30° S to the equator?
    Trade winds
    Westerlies
    Polar easterlies
    Monsoon winds
  • 25. Which phenomenon explains why winds curve instead of blowing straight?
    Coriolis effect
    Ocean currents
    Gravitational pull
    Atmospheric pressure
  • 1. What type of pressure exists at 30 degrees north and south latitudes?
    Constant pressure
    No pressure
    Low pressure
    High pressure
  • 28. In what direction do trade winds blow in the Northern Hemisphere?
    From the north to the south
    From the east to the west
    From the west to the east
    From the south to the north
  • 24. Which hemisphere has trade winds that curve to the left?
    Western Hemisphere
    Eastern Hemisphere
