Briefly explain how the Sun generates energy.
 
  What will be an ideal response?

Question 2

Geological evidence points to a history of extended ice ages in Earth's history. How did Earth recover from this snowball phase?
 
  A) The increased ice coverage on Earth's surface absorbed more sunlight than water and rocks, thus gradually heating Earth until the ice melted.
  B) Life vanished, leading to an increase in CO2, and increased global warming, eventually melting the ice.
  C) Volcanoes continued to inject CO2 into Earth's atmosphere, increasing the greenhouse effect to the point where ice melted.
  D) Plate tectonics gradually subducted all the ice below Earth's surface.
  E) As the Sun aged, it grew brighter and increased Earth's temperature, melting the ice.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
