The period during which the sun lacned sun spots is referred to as the :

  • A.Milankovitch Mechanism
  • B.Maunder Minimum
  • C.Year without a summer
  • D.Last ICE AGE

Answer: B

The period without sunspots is the Maunder Minimum.

From about 1645 to 1715 astronomers recorded almost no sunspots. E. W. Maunder drew attention to it, and the period coincided with the coldest part of the Little Ice Age in Europe.

Milankovitch cycles are long variations in the earth's orbit and tilt that drive ice ages. The 'Year Without a Summer' was 1816, caused by the 1815 eruption of Mount Tambora, not by a lack of sunspots, and the last ice age ended about 11,700 years ago.
