they were huge, deep and wide ranging, creating new landscape as far south as New York. When they receded they left the thousands of shallow lakes in northern US and Canada. They ground mountains into little pebbles and pushed rocks thousands of miles from their origins
hope this helps!
The largest Glacier presently is the Lambert Glacier - appx. 80Km. wide, 500Km. long.
If the theory of the big freeze (that at one time the Entire Earth was frozen) then the answer is "as big as the planet".
Even if it's not, we know for sure that glaciers once covered all of North America down to well below New York City (and Europe to France as well as Asia into China).
supplement And check out Beardmore glacier in wikipedia.org, where there is an authoritative article
Well, soon after the algae invented photosynthesis, that sucked most of the CO2 and methane from the atmosphere. This also put up the O2 content of the air (for the magic of photosynthesis is that plants may split water into O2 and H, which they used to build complex molecules.) And allowed the iron dissolved in the oceans to precipitate out as iron oxides, the 'banded iron deposits' of commercial importance in US, Europe, Aus and so on. Maybe the oil was made then?? And the Earth went into a 'snowball earth' phase, when it was all one glacier. But the volcanoes still put out CO2 and methane, and the ice melted eventually. Which is considered a GOOD THING. Look up the Siderian period in wikipedia.org for some speculations on this. Have Fun.
Glaciers actually do not have an average size. They range from a few acres to hundreds of square miles. Some are several hundred to one thousand feet thick.
the average glacier is about 3,000 tons. They can gets as small as 1 ton
Larger than 500 ft
Rlly Big!

Valley glaciers form on high mountain valleys and are long and narrow. Continental glaciers covers much of a continent or large island.

No, there are no glaciers in Lake Superior. However, glaciers CREATED Lake Superior, in fact, all of the Great Lakes. Lake Superior may have large floes of ice in winter.

The statement that is accurate is that glaciers can carry both small particles and large boulders. Glaciers can carry both small particles and large boulders.

No. The Alps are a mountain range in Europe. Glaciers are large masses of ice that move slowly due to their weight. Glaciers are commonly found in mountain ranges such as the Alps/
