waters of ice

• The beginning of a river is the source/headwater
• Glaciers are often called rivers of ice because they flow like rivers.
• A firn refers to the snow that is compacting at the top of a glacier.
• A semi-circular,often bowl-like, depression carved into a mountain by a glacier is a cirque.
• Arete is a sharp mountain ridge seperating 2 or more adjacent cirques.
• A crevasse is a deep break in the ice that forms as the ice goes over uneven ground.
• The bottom of a glacier is glacial bed.
• The tip,or leading edge, of a glacier and is often where the ice melts or breaks off is the snout/terminus.
• Alpine glaciers are glaciers that form in mountains because the cold of the mountain tops allows the snow to acummulate without ever melting, so that it slowly turns into ice under its own weight.
• Several cirque glaciers can join together to form a valley glacier.
• Continental glaciers are glaciers that cover large areas such as Antarctica and Greenland and are a result of the cold climate that envelops those parts of the earth.
• Continental glaciers are continuous masses of ice that are much larger than alpine glaciers.
• Small continental glaciers are called ice fields.
• Big continental glaciers are called ice sheets.
