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.
What is a rock that is moved by a glacier?
A rock that is moved by a glacier is called a glacial erratic. These rocks can vary in size and type, and are often deposited in areas far from their original source by the movement of the glacier. Glacial erratics are important indicators of past glacial activity and can provide valuable information about the history of a region.
What is evidence that a glaciers was at?
Presence of glacial striations, moraines, and glacial valleys are evidence that a glacier was there. These features are formed by the movement and deposition of ice, rocks, and sediment as the glacier advances and retreats. Additionally, erratic boulders, cirques, and U-shaped valleys are also typical evidence of past glacial activity.
What features indicates that many continents were once near Earths South Pole?
A) glacial deposits
A huge boulder resting on a completely different type of bedrock is glacial zones is?
likely a result of glacial action, where the boulder was transported and deposited by a glacier onto the different bedrock type. This process is known as glacial erratics and is common in glacial zones where ice sheets and glaciers have covered the landscape, carrying rocks of various sizes and types as they move.

What is an erratic boulder?
An erratic boulder is a boulder of rock which is of a different type than the local rocks. Erratic boulders are ofter more correctly termed glacial erractics as they were generally picked up, transported (often many hundreds of miles) and then finally deposited by melting glaciers.
How do you think the glacial erratic got its name?
it got all of the nutrients it needs
Large boulders left as glacial deposits are called what?
Erratic blocks or "erratics" for short.

How is there evidence of an ice age?
Evidence of an ice age can be found in geological features like moraines and glacial striations, as well as in the distribution of glacial deposits and erratic boulders. Additionally, analysis of ice cores provides information on past climate conditions and the presence of isotopes indicative of glacial periods. Fossils of cold-adapted plants and animals further support the occurrence of ice ages.
Is Erratic erosion or depositional?
Erratic refers to a type of glacial deposit that is transported by glaciers and deposited in locations far from their source, often as a result of ice movement during the last Ice Age. Therefore, erratic is associated with depositional processes.
How are erratics and drumlins alike?
Erratics and drumlins are both types of geological formations associated with glacial activity. Erratics are large boulders transported and deposited by glaciers, often found in areas where the surrounding rock is different from the rock type of the erratic. Drumlins, on the other hand, are elongated hills formed from glacial till that has been shaped by the movement of ice. Both features provide evidence of past glacial movements and help in understanding the dynamics of glacial landscapes.
What features indicates that many continents were once near Earths South Pole?
A) glacial deposits
What is Characteristics of glacial movement?
A characteristic of glacial movement is movement depends on the balance between accumulation and wastage.
A huge boulder resting on a completely different type of bedrock is glacial zones is?

This process is known as glacial erratics and is common in glacial zones where ice sheets and glaciers have covered the landscape, carrying rocks of various sizes and types as they move.
