Question

explain why some areas of land that were once covered by glaciers during the last ice age is now rising in elevation?

this is a 9th grade science question! someone please answer please!!

Answer 1

The weight of the ice compressed the material below it. Now that the ice is gone, the material is expanding upward to its previous height.

Answer 2

confident, the southern fringe of the continental glacier ran from what's immediately long island to Nantucket and Cape Cod. long island's hills have been built from the terminal moraines that marked the fringe of the glacier the place it had pushed up rocks and dirt. The flat factors to the south of the hills are the outwash undeniable shaped from erosion of the hills. See excerpt from Wikipedia article on Outer Lands. The Outer Lands is a term denoting the renowned terminal moraine archipelagic area off the southern coast of recent England interior u.s.. This area of Massachusetts, Rhode Island and long island, involves the peninsula of Cape Cod and the islands of Martha's vineyard, Nantucket, Block Island and long island, besides as surrounding islets. The Outer Lands kinds the insular northeasternmost extension of North u.s.'s Atlantic Coastal undeniable. The islands of the Outer Lands have been shaped via the end results of the recession of the Laurentide ice sheet in the process the Wisconsin glaciation although the existence of this archipelago is substantially regarded via geographers, it is not given a particular call; "Outer Lands" is an older term used via naturalists and observed via author Dorothy Sterling for her organic history instruction manual of an identical call.

Answer 3

It is called "isostatic rebound". The weight of the glaciers pressed down the land it was sitting on. As the glaciers melt, the land underneath rises back up to where it was before the glaciers pressed it down.

It is similar to sitting on a cushion. Your weight presses the top of the cushion down. However, once you stand up (i.e., remove the weight from the cushion), the mattress returns to its original form.

Answer 4

think of the crust as a raft floating in some water (the water would be the mantle of course). then the glacier would be like someone getting onto that raft. it sinks down a ways. when that person gets off the raft it buoys back up to its original height. this is exactly what the crust is doing now that the ice is gone.
