3. Global Warming Term for the observed century-scale rise in average temperature of Earth’s Climate System Multiple scientific evidence shows that the climate system is warming increase of near-surface atmospheric temperature is the measure of global warming www.livescience.com

4. What is a glacier? What are glacial ages? Fallen Snow Snow in one location Occupies 10% of earth’s total land area Also known as “Ice Age” Ice sheets and Glaciers exist period which long-term cooling takes place

5. https://en.wikipedia.org/wiki/Margerie_Glacier

6. What causes the alternation of glacial and interglacial stages? Atmospheric composition Decreases in atmospheric CO2, started the long-term cooling trend that led to glaciation. Ocean Currents Carries heat to high latitude areas

7. Plate Tectonics describes the large-scale motion of Earth's lithosphere Accepted geoscientific community after seafloor spreading was validated builds the concept of continental drift

9. Variations in Earth’s orbit eccentricity - Determines the amount by which its orbit around another body deviates from a perfect circle. Earth’s eccentricity is 0.0167 obliquity - Angle between the planes of earth's equator and orbit having a value of about 23° precession - Slow changes in an astronomical body's rotational or orbital parameters

11. What happens to life during ice ages? Plants Froze because of the cold temperature Animals Died because of the cold temperature, and loss of food source which is Plants Humans Died because of freezing temperature, and loss of food source which is plants and animals
