Changes in the shape of Earth’s orbit around the Sun are called ___.

• eccentricity

• obliquity

If you increase Earth's axial tilt (obliquity), what will happen to the seasons?

• milder summers and milder winters

• hotter summers and colder winters

• cold summer and cold winters

• extreme summers and extreme winters

Which of the following has caused repeating 100,000-year cycles of ice ages in the past?

• an increase in sun spots

• several major volcanic eruptions

• changes in Earth's orbit and the tilt of its axis

• continental drift

Earth is currently in an interglacial period (a period of milder climate between Ice Ages). If there were no human influences on climate, scientists say Earth’s current orbital positions within the Milankovitch cycles predict our planet should be cooling, not warming, continuing a long-term cooling trend that began 6,000 years ago.

• True

• False
