What term describes all types of glacial deposits?

till is the name of the material. In most cases all glacial-related deposits are unsorted and unstratified.


Where can erratic boulders be found?

Erratic boulders can be found in various parts of the world, primarily in regions that were affected by glaciation during the last Ice Age. These boulders are typically large and made of different rock types than the surrounding area, having been transported by glaciers and deposited as the ice melted. Notable locations where erratic boulders can be seen include Scandinavia, North America, and parts of northern Europe.


What are layers or ridges of glacial till?

Layers or ridges of glacial till, often referred to as moraines, are accumulations of debris deposited by glaciers as they advance and retreat. These formations consist of a mixture of clay, silt, sand, and larger rocks that have been eroded and transported by the ice. Moraines can vary in shape and size, typically appearing as ridges along the sides or at the terminus of a glacier, and they provide valuable information about past glacial movements and the environmental conditions during their formation.


What did Scientists discovered evidence that indicates that there have probably been?

Scientists have discovered evidence suggesting that there have likely been multiple ice ages in Earth's history. This evidence includes geological records, such as glacial deposits and landforms, as well as the analysis of ice cores and other climate indicators. The presence of these clues indicates that the Earth has experienced periods of extensive glaciation over millions of years.


How can you tell how far a rock or boulder has been moved by a glacier?

To determine how far a rock or boulder has been moved by a glacier, scientists often examine the rock's shape and striations, which can indicate the direction of glacial flow. Additionally, comparing the rock's composition to the surrounding geology helps identify its origin. By mapping the distribution of similar rocks and using tools like GPS or surveying, researchers can estimate the distance the glacier has transported the boulder. Analyzing sediment layers and glacial deposits also provides insights into the glacier's movement history.

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 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 is an isolated boulder left by a glacier called?

An isolated boulder left by a glacier is called a glacial erratic. These boulders are often different in composition compared to the surrounding rocks, as they have been transported and deposited by glaciers.


How was Yeager rock formed?

Yeager Rock is an example of a glacial erratic. Basically in a previous ice age glaciation it would have been picked up from a different area and transported to its current location in the ice flow.


Is a moraine formed by glacial deposition?

Yes, a moraine is formed by glacial deposition. It is a landform made up of unsorted rock material (till) that has been transported and deposited by a glacier as it moves and melts.

A deposit of rock particles that are scratched and unsorted has most likely been transported and deposited by what?

The deposit is most likely transported and deposited by a glacier. Glaciers are massive sheets of ice that can carry rock particles long distances and leave behind unsorted and scratched deposits as they melt and retreat. This process is known as glacial deposition.


Where does glacial drift come from?

Glacial drift is material that has been eroded, transported, and deposited by glaciers. It includes a mix of rock fragments, sediments, and debris that are carried along by ice and then left behind as the glacier melts or retreats. Glacial drift can vary in size and composition, depending on the location and movement of the glaciers.


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 :)


Sediment left behind when a glacier melts is called?

Glacial drift.Glacial drift.
