what is the difference between valley glaciers and continental glaciers?

Answer 1

Valley (or Alpine) Glaciers are just what the name suggests - they're galciers that form in valleys, not necessarily the traditional V shapped valley but any depression in the ground. This is the type of glacier you find in mountainous regions such as the Andes, Rockies, Himalaya etc.

Continental Glaciers are another name for Ice Sheets, they're not glaciers in the conventional sense but are huge ice sheets covering thousands of square miles. There's two of them - Greenland and Antarctica.

There are other types of glacier as well including tidewater, polar, temperate and plateau.
