The two types of glaciers are Valley or Alpine glaciers Continental glaciers. The difference between them is where they flow. Valley glaciers flow in mountain valleys from high to low elevations. Continental glaciers or ice sheets flow over vast unconfined land areas.
The most basic difference is that sea ice forms from salty ocean water, whereas icebergs, glaciers, and lake ice form from fresh water or snow. Sea ice grows, forms, and melts strictly in the ocean. Glaciers are considered land ice, and icebergs are chunks of ice that break off of glaciers and fall into the ocean.
