How glacial spillways are formed?
Glacial spillways are formed when meltwater from a retreating glacier creates a pathway through moraines or other glacial deposits. As the glacier retreats, the trapped water is released, carving out a channel that can carry large volumes of water downstream. These spillways are important for draining glacial lakes and preventing catastrophic flooding.
What are erratics?
Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time. improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding. i hope this helps :)
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.
What is a spoon-shaped hill of a till?
A spoon-shaped hill of till is a glacial landform formed when a glacier deposits a large amount of material, called till, as it melts. The material is deposited in a distinctive shape resembling an elongated mound with a rounded end, similar to the shape of a spoon. These hills are common in areas that have been shaped by glacial activity.
What is Virginia's has large deposits of sand and gravel?
Virginia has large deposits of sand and gravel due to its geological history involving the erosion of ancient mountain ranges like the Appalachians. These deposits are commonly found in river valleys, coastal areas, and inland regions, and are important resources for construction, infrastructure development, and the production of concrete.
Large boulders left as glacial deposits are called what?
Erratic blocks or "erratics" for short.

How can you identify the deposited materials that were left there directly by a glacial ice deposits?
You can identify deposited materials left by glacial ice deposits based on their composition, size, and sorting. Glacial deposits often consist of a mix of sediment sizes (clay to large boulders), show little sorting, and may have scratches or striations caused by the movement of ice. Additionally, the presence of erratics (rocks different from the surrounding material) can also indicate glacial deposition.
How glacial spillways are formed?

As the glacier retreats, the trapped water is released, carving out a channel that can carry large volumes of water downstream. These spillways are important for draining glacial lakes and preventing catastrophic flooding.
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.
Depressions left by melted blocks of ice in glacial deposits?
The depressions left by melted blocks of ice in glacial deposits are called kettle holes. They are circular or oval-shaped depressions that form when large chunks of ice left behind by a retreating glacier become buried in sediment. When the ice eventually melts, it creates a hole in the ground.
What is the name of a precious metal found in large deposits in south America?
Bauxita
Why are northern plain primarily agricultural belt?
due to large alluvium deposits and fertile soil next to the rivers

Why are Jamaicans large deposits of bauxite to Caribbean islands?

Which term refers to large deposits of minerals found in one place?
The term for large deposits of minerals found in one place is "mineral reserve." These reserves are typically identified through geological surveys and assessments, and they form the basis for mining operations.
