Sun Cycles And The Earth

|This quiz asks you to recognize the cycles that affect the earth's climate. |
Ice age "reoccurring regularity" shows that our Sun is a star that expands and contracts regularly. Total solar energy upon the planets varies over long cycles of time. At the maximum glacial age the solar energy would have decreased. The Earth's temperature would have been cooler. It takes small variations in the Sun's radiation to dramatically change the Earth's climate. This quiz asks you to guess or know the causes of some of the earth's cycles.
