OUTPUT from page 26 of your science journal. This will go under your squirrel drawing.

WHAT IS PERMAFROST? Permafrost is a permanently frozen layer below the Earths surface. It consists of soil, gravel, and sand, usually bound together by ice. Permafrost usually remains at or below 0C (32F) for at least two years.

Permafrost can be found on land and below the ocean floor. It is found in areas where temperatures rarely rise above freezing. This means permafrost is often found in Arctic regions such as Greenland, the U.S. state of Alaska, Russia, China, and Eastern Europe.”  http://nationalgeographic.org/encyclopedia/permafrost/
