This colorful and detailed PowerPoint and bundle covers the types of glaciers, parts of a glacier, and features created by weathering, erosion and depositions as the glacier moves.
A glacier is a thick ice mass that forms over hundreds or thousands of years. First, the types of glaciers and different parts of the glacier. Glacial types include valley glacier, piedmont glacier, ice sheet and ice cap. Parts of a glacier include zone of accumulation and zone of ablation.
Next, the process in a glacier that causes erosion is discussed. This erosion can cause specific features left behind by the glacier. These features include, glacial troughs, horns, arêtes, hanging valleys, cirques, tarns and fjords.
Finally, glacial deposition is discussed. As glaciers weather and erode rock, the sediments, or drift, are moved and deposited. These deposits are called moraines and are named for where they are deposited and whether they were carried by the glacial ice or the glacial melt water. Glacial moraines include lateral moraine, end moraine, terminal moraine, ground moraine, medial moraine and recessional moraine. Some deposition occurs beyond the reach of the glacier in an area called the outwash plain and can produce kettle lakes due to dead ice from calving. And some deposition occurs under the glacier creating features called drumlins, eskers, and kames.
