Where are moraines found?
A moraine is a unsorted deposit of material left behind at the head (the front of a Glacier
What are moraines composed of?
Moraines are a type of hill surrounding a kettle formed as glaciers melt and retreat. The kettle is formed by a very large chuck of ice that was left behind. The sand, gravel and rocks flowing with the water from the retreating glacier go around the ice chunk and form the moraines. There are places in Wisconsin called the Kettle Moraine Area where these can be seen. Often people remove the moraines for the sand and gravel that they can sell. This material is used in construction.
What is Deposits formed when wind blown sediments settle and build up behind an obstacle?
Dunes.
What are moraines made up of?
Moraine is the term used for the unsorted rock and material deposited by the melting and retreat of a glacier. So moraines are mainly rocky areas that used to be covered by a glacier.
Is glacial lake caused by erosion or deposition?
A glacial lake is a lake with origins in a melted glacier. Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks.
When deposits of till build up What is left behind?
When deposits of till build up, they can leave behind various landforms such as moraines, drumlins, eskers, and outwash plains. These features are created by the movement of glaciers and the deposition of sediments as the glacier retreats.
What are depressions left by melted blocks of ice in glacial deposits called?
The depressions left behind are called kettles. The raised areas are called moraines.
What do you call a deposit of clay sandand gravel left behind by a glacier?
Apron: Defined as an area covered by sand and gravel deposited at the front of a glacial moraine Outwash material/sandur. Or if into water a varve.
Where are moraines found?
A moraine is a unsorted deposit of material left behind at the head (the front of a Glacier
What are large deposits of boulders called?
The debris of boulders eroded and carried down by glaciers will eventually form moraines (mounds) where the front of the glacier melts and retreats, leaving the debris behind. Moraines can be high and wide enough to form a dam, behind which glacial melt water is trapped and lakes are formed.
Where is the morianes?
Moraines are the rocks, stones, pebbles, and fragments of rocks carried along at the base of glaciers. You can also see Moraines in the valleys left behind after the glaciers melted at the end of the last Ice Age.
What are glacial deposits?
Glacial deposits are layers of rock, above the bedrock, as produced by the recent ice age(s), the glaciers as they moved across the planet, would pick up debris along the way, and as they moved, to say the area of, Washington State, besides, forming the Puget Sound Basin, called, a Fjord, later melting and leaving behind the various deposits, possibly gem material, gold, diamod's, etc. So theoretically, there could be, deposits, left by recent glaciation, rich in valuable minerals,

Are water dams created by the environment?
When glaciers melted after the last ice-age and the ice retreated, they often left moraine deposits behind. These natural dam materials prevented the glacier's melt water from escaping. This is one example of the natural creation of a dam wall - which holds back the lake of glacial water formed behind.
What do glaciers leave behind as the retreat?
As glaciers retreat, they leave behind deposits of rocks.
