Well..I learned this in School.
The Great Lakes are the result of glacial scour and pooling of meltwater at the rim of the receding ice. When the enormous mass of the continental ice sheet retreated, the Great Lakes began gradually moving south due to isostatic rebound of the north shore. Niagara falls is also a product of the glaciation, as is the course of the Ohio River, which largely supplanted the prior Teays river.
the lakes were even larger than they are today because of the enormous volume of water from the melting glaciers. They eventually shrank to their present size as much of the glacialmelt waterdrained into the ocean.
cold period, glacial period
It is recorded that the last glacial period ended in 10,500 BC. That was supposedly the end of what is commonly known as the "Ice Age."
Sea levels drop globally during a glacial period as seawater is taken up in the ice sheets.
10000 yrs ago
no
A glacial period is like the time of ice ages, when the most of the earth is covered in ice and snow.
the last glacial period
Post-glacial rebound (sometimes called continental rebound, glacial isostasy, glacial isostatic adjustment) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostasy.
Adjective:Of or relating to a period of milder climate between two glacial periods. Noun:An interglacial period.
Periods of rapid glacial movement are referred to as glacial surges. These events are characterized by a sudden increase in glacial velocity, resulting in the movement of large quantities of ice over short periods of time. Glacial surges can drastically reshape the landscape and contribute to changes in local ecosystems.
No: glacial activity occurs in all glacial phases of all Ice Ages, and we now see the results of the latest within the present Ice Age.
Yes. We currently live in an "interglacial period" of the Quaternary Ice Age. Some people confuse "ice age" with a "glacial period" within an ice age.
