The mass of ice from the continental ice sheets had depressed the rock beneath it over millennia. At the end of the last glacial period, while the rock was still depressed, the Saint Lawrence and Ottawa River valleys, as well as modern Lake Champlain, at that time Lake Vermont, were below sea level and flooded with rising worldwide sea levels, once the ice no longer prevented the ocean from ...
The process of creating an "impoundment" of water is itself called "impoundment". Ice cap: A body of frozen water less than 50,000 km 2 not constrained by topographical features (i.e., they will lie over the top of mountains) Ice field: A body of frozen water constrained by topographical features: Ice sheet: A body of frozen water more than ...
Once nilas has formed, a quite different growth process occurs, in which water freezes on to the bottom of the existing ice sheet, a process called congelation growth. This growth process yields first-year ice. In rough water, fresh sea ice is formed by the cooling of the ocean as heat is lost into the atmosphere.
These allowed large amounts of water to flow from Lake Agassiz into Lake Minong. A series of ice advances and retreats between 10,500 and 9,500 YBP blocked the Lake Nipigon outlet and the other low level outlets, creating intermittent catastrophic outbursts of water into the Lake Minong basin. [1] These large inflows of water raised Lake Minong ...

As the temperature continues to drop, the water on the surface may get cold enough to freeze and the lake/ocean begins to ice over. A new thermocline develops where the densest water (4 °C (39 °F)) sinks to the bottom, and the less dense water (water that is approaching the freezing point) rises to the top.
