1 gram = 15.432 358 353 grain In thâ¦e US, in medicine, the use of grains is disappearing and seems to be somewhat approximate: A 60 mg dose may be described as 1 grain, but you should expect 1 grain to be about 65 mg, or 0.065 grams.
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.
How Glaciers Form. Glaciers form when more snow falls than melts each year. Over many years, layer upon layer of snow compacts and turns to ice. There are two different types of glaciers: continental glaciers and valley glaciers. Each type forms some unique features through erosion and deposition. An example of each type is pictured in Figure below. 1  A continental glacier is spread out over a huge area. It may cover most of a continent. 2  A valley glacier is long and narrow. Valley glaciers form in mountains and flow downhill through mountain river valleys. (A) The continent of Antarctica is covered with a continental glacier. (B) A valley glacier in the Canadian Rockies.
