Answer Key

  1. The Earth’sseasons are due to the tilt of its axis.
  2. Shorter days (with less sunshine) and longer nights cause cooler temperatures.
  3. Longer days allow more sunshine to warm the ground and atmosphere.
  4. The weather conditions during a blizzard are winds over 35 mph, and poor visibility.
  5. A monsoon is six months of rain in the tropics.
  6. Scientists have learned that most hurricanes form after the ocean water warms up past 80°F, so hurricanes are more likely to form during months when water temperatures are above this temperature.
  7. Doppler weather radar can track the details of a hurricane and thus provide warning to the population of an area threatened.
  8. A foehn wind is a relatively warm and dry wind descending a mountain front.
  9. Arctic cold fronts cause high evaporation rates as they pass over the Great Lakes, triggering heavy snowstorms once they hit land.
  10. A storm that moves northeast along the east coast.
