Question

The tilt of the Earth's axis of rotation changes from approximately 22.5° to 24.5° over a period of 41,000 years. This causes global climate change. When the tilt is small there is
Select one:
a. less difference in gravitational pull in the middle and high latitudes
b. less climatic variation between the summer and winter seasons in the middle and high latitudes
c. greater difference in solar energy received at the Earth's closest and farthest locations from the Sun
d. greater difference in duration of days and nights at the Earth's closest and farthest locations from the Sun

Answer 1

b. less climatic variation between the summer and winter seasons in the middle and high latitudes

As the tilt becomes higher (approaches 24 degrees) there is greater variation between the summer and winter months, due to the fact that the tilt toward the sun in the summer and away from the sun in the winter are more pronounced.
