The Medieval Climate Anomaly was a(n)
 
  A) the current period of unprecedented warming that has occurred since 1980.
  B) higher than average temperatures throughout Asia, but mostly affecting China, that occurred during the Classical Chinese Medieval Period.
  C) a global cooling trend that lasted from approximately 1250 to 1850.
  D) a mild climate episode that lasted from 800 to 1200 and involved warmer than normal conditions in the North Atlantic region (e.g., Greenland and Iceland).
  E) warming trend that occurred from the Last Glacial Maximum until the Little Ice Age (1250).

Question 2

Examine in detail the various ways in which wind speed and direction are determined by the pressure gradient force, the Coriolis force, and friction.
 
  What will be an ideal response?

Answer to Question 1

D

Answer to Question 2

If air moved in response to pressure gradients alone, it would travel perpendicular to isobars. The greater the pressure gradient, the stronger the winds. With the addition of the Coriolis force, winds in the Northern Hemisphere flow counter clockwise around low pressure areas and clockwise around high pressure areas, flowing parallel to isobars (geostrophic winds). The friction force adds a countering force to Coriolis, producing winds that spiral our of a high pressure area and into a low-pressure areas.
