Fluvial deposits are more likely to sort sediments based on size and shape due to the moving water, while glacial deposits tend to mix different-sized sediments. Fluvial deposits often form distinct layers or beds, reflecting changes in flow intensity or sediment composition, whereas glacial deposits are typically unsorted and lack clear layering. Fluvial deposits are common in low-energy environments like rivers and deltas, while glacial deposits are more common in high-energy settings like mountain valleys and ice sheets.

Why is a glacial till not folded?
Glacial till is unconsolidated and consists of mixtures of clay, silt, sand, gravel, and boulders. Due to its loose and poorly compacted nature, glacial till does not exhibit folding. Instead, it is more likely to experience deformation through shearing or faulting under pressure.
How are landforms commonly classified?
Landforms are commonly classified based on their shape, origin, and location. Shape-based classifications categorize landforms as mountains, valleys, plains, plateaus, and more. Origin-based classifications group landforms as volcanic, erosional, depositional, or tectonic in nature. Locational classifications are based on geographic features such as coastal, fluvial, glacial, or desert landforms.
How does glacial ice differ from regular ice?
Glacial ice is much more solid then regular ice. Glacial ice is also alot colder than regular ice. Glacial ice can also be up to 1/2 a mile thick. Glaciation is aan extremly powerful force. 2. Glaciation happend very recently in geologic terms and there has not been enough time for the glacial features to be worn away.
Boulders carried many miles by a glacier are called?
Boulders that have been carried by a glacier have a couple names, but most commonly they are referred to as glacial boulders or erratics. If you're interested in learning more about glacial boulders, the Iowa Department of Natural Resources has a pretty good article about them; as Iowa and most of the American Midwest were covered by glaciers during the last Ice Age, glacial boulders are fairly common there. http://www.igsb.uiowa.edu/browse/boulders/boulders.htm
How is snow transformed into glacial ice?
Snow is transformed into glacial ice through a process called firnification, where successive layers of snow are compressed under their weight into firn, a compacted snow with some air pockets. Over time, the firn undergoes further compaction and recrystallization, becoming glacial ice. This process can take several decades to centuries depending on the accumulation rate and temperatures.

What is another word for glacial episode?
Glacial periods, episode of glaciation, glacial age, etc. They all the same thing as an Ice Age. If you want something more specific, I would check websites that have information on weather and climates.
What are examples of till moraine and kettle?
Glacial weathering forms till moraine kettles and also kettles lakes. More specifically the acts of glacial depositionforms these.
Is glacial succession primary?
Glacial succession is a type of primary succession, as it involves the colonization of barren land that has been exposed by glacial retreat. Over time, pioneer species establish themselves and create conditions for more complex plant communities to develop.
How much money does a glacial geologist make?
They make around 97,000 dollars a year. This is the starting salary for a glacial geologist, the potential is to make much more as their career develops.
Which is more conductive between glacial acetic acid and 6 M acetic acid?
Conductivity of glacial Ac.ac. is lower, because there are (almost) none free protons. To get them 'free' to conduct some water is needed.
What types of glaciers pluck?
Glaciers primarily pluck resistant rock types such as granite, gneiss, and schist. These types of rocks are more likely to fracture and break when exposed to the stresses of glacial movement, allowing the glacier to pluck and transport them as it flows.
What is a sharp pyramid-shaped peak that forms when three or more cirques erode a mountain?
Glacial horn

Which glacial landforms require more than one glacier to form?
aretes,hanging valleys,horns,and drumlins
Which would be likely to occur in a region of continental glaciation but not in a region of valley?
The presence of large moraines (deposits of glacial till), erratic rocks (boulders carried by glaciers), and drumlins (elongated hills formed by glacial action) would be more likely in a region of continental glaciation compared to a region of valley glaciation. The larger scale and extensive coverage of ice in continental glaciation are responsible for shaping the landscape in these ways.
