Final answer:
Glaciers form on mountainsides and move downward through valleys. There are different types of glaciers such as alpine glaciers, ice caps, and ice sheets.
Step-by-step explanation:
Glaciers are large masses of ice that form on mountainsides and move downward through valleys. There are different types of glaciers based on their size and location. Alpine glaciers are found in mountainous regions and are confined to valleys or cirques. Ice caps are smaller than ice sheets and are dome-shaped, covering mountain tops or plateau areas. Ice sheets, on the other hand, are much larger and cover large areas of land, like Greenland and Antarctica.
