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

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.

There are more nerve cells in one human brain than there are stars in the Milky Way.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

Critical care patients are twice as likely to receive the wrong medication. Of these errors, 20% are life-threatening, and 42% require additional life-sustaining treatments.

Children of people with alcoholism are more inclined to drink alcohol or use hard drugs. In fact, they are 400 times more likely to use hard drugs than those who do not have a family history of alcohol addiction.

Did you know?

Once thought to have neurofibromatosis, Joseph Merrick (also known as "the elephant man") is now, in retrospect, thought by clinical experts to have had Proteus syndrome. This endocrine disease causes continued and abnormal growth of the bones, muscles, skin, and so on and can become completely debilitating with severe deformities occurring anywhere on the body.
