Carve away land, Basins and lakes, Islands made out of sand
I only know that alpine glaciers can carve deep u-shaped valleys in the mountains.
Glaciers
As glaciers move, they can carve out deep depressions in the land called cirques. When the glacier retreats or melts, these cirques can become filled with water, forming lakes. Glaciers can also create moraines, which are piles of debris that dam up valleys, creating lakes behind them.

No, Lake Erie is a glacial lake. That means over thousands of years, glaciers approached and receded across what is now Canada and now the US. The friction of ice moving across the land carved out 5 basins. At first, the basins were small and filled with rain water and water that melted as the glaciers receded. The basins got bigger and deeper over those thousands of years. We now call those basins The Great Lakes, one of which is Lake Erie. By the way, a lake can never be a glacier, just as a glacier can never be a lake. But glaciers can carve out deep holes where lakes can form. Lake Erie averages a 62 foot depth, and 210 feet at it's deepest.
Glaciers carve out vallys and lakes. They will pick up sediment and move it to other places.
Glaciers can carve out valleys and create u-shaped valleys through the process of glacial erosion. As glaciers move, they transport large amounts of sediment and rocks that accumulate at their edges, forming moraines. When glaciers retreat, they leave behind depressions that can fill with water, creating lakes.
Glaciers in Yosemite National Park helped carve Yosemite Valley. There are currently two glaciers in Yosemite, both of which are retreating. The two are called Lyell Glacier and Maclure Glacier.
The main impact that melting glaciers have is that the sea level rises. If all the glaciers in the world melt, the rise in sea level will be very substantial and will cause massive flooding of coastal regions. That would cause a very big impact.
