Glaciers smoothed down mountains, built up hills, carved out lakes, and formed rivers.

Suggestions
- Copy and illustrate Psalm 147:15-18.
- Read about rocks that are thought to have been moved by ice — otherwise known as glacial erratics.
- Study the anatomy of a glacier at PBS.org.
- Read about how glaciers affect the land at the National Snow and Ice Data Center.
- What is the difference between a glacier and an iceberg? Find out at the University of Guelph. Make a compare/contrast diagram or chart showing the similarities and differences.
- Read about the RMS Titanic at KidsDiscover.com.
- View the mouth of the mighty Mississippi at NASA.
- Study the anatomy of the Mississippi River at AmericasWetlandResources.com.
- Study the anatomy of a geyser at the National Park Service.
- Something to do #1: In case you are unable to locate the June 1926 National Geographic Magazine, you can still read about icebergs at Ohio State.
- Something to do #2: Print out a map of the U.S. and Canada at EduPlace.com. Then you can use a map of the North American ice sheets at AnswersInGenesis.org to mark the parts of your map that were thought to have been covered with ice.
- Something to do #3: You may find this section in the Handbook of Nature Study helpful for finding out How a Brook Drops Its Load. You’ll find nature journal resources below.
- Something to do #4: You’ll find activities below to help with this experiment.
- Copy and memorize Job 36:26.
- More about water and ice from the Book of Knowledge:
Glaciers are great streams of moving ice. Countless fragile and gossamer snowflakes, pressed closely together, form the heavy ice of which they are made. Sometimes glaciers are long and narrow, like rivers; sometimes they are very broad, extending hundreds or thousands of miles in every direction….
A typical valley glacier, like a river, has three parts: a headwater area, a main course and a downstream end. In the headwater region, from which the glacier is supplied, there are wide and deep expanses of snow and ice. Each new snowfall buries and presses down upon these white fields until the upper layers of fallen snowflakes change into little grains of ice, each one separate from the others. This granular mass is called the névé or firn. In time, with constantly added pressure, the névé becomes ice that is closely packed. Even this more solid ice, however, shows that it was made from falls of snowflakes; for each fall of snow there is a distinct layer of ice.
Soon the ice begins to flow downhill. If you have ever picked icicles from the edge of a roof or from a bush, you know that ice is brittle; it will break but not bend. However, if a mass of ice particles is subjected to very heavy pressure, the ice will flow as a liquid does, although much more slowly. In the head region of a glacier, the great pressure of the thick ice and snow above causes the lower portion of the ice to flow out from beneath the top part. This flowing ice forms the river of the valley glacier.
