Global Ice Ages
When most people hear the words Ice Age, they think of glaciers covering much of North America and Eurasia, animals like mammoths and saber-toothed cats, and Cro-Magnon people painting cave walls. These things come to mind because the words "Ice Age" often refer to the last time that glaciers extended over a large portion of the Earth's surface. The amount of ice on the Earth's surface has varied greatly through time. During most of the last 1 billion years the globe had no permanent ice. However, sometimes large areas of the globe were covered with vast ice sheets. These times are known as ice ages.
