Glaciers

Glaciers are large, dynamic bodies of ice that form over long periods of time when snow accumulation exceeds ice ablation. They are among the most significant forces shaping Earth's landscape over long time scales. Glaciers are currently found at Earth's poles and in mid-latitude and equatorial mountains.

Is sediment of different sized particles left by ice from glaciers called outwash?

No, sediment of different sized particles left by ice from glaciers is called glacial till. Outwash is sediment deposited by meltwater streams flowing away from a glacier.

Why do volcanoes have glaciers on their slopes?

Well... not all volcanoes have glaciers on their slopes! Some volcanoes have glaciers on their slopes because the volcano just isn't hot!

The volcano might be inactive, 'asleep' or even 'dead'... so there is no activity in it, which means no hot lava is moving about in it, so it doesn't heat up it's slopes (so they stay cold enough for the glacier not to melt or anything)!

How are retreating glaciers and advancing glaciers the same?

Retreating glaciers and advancing glaciers are both affected by changes in temperature and precipitation. They both play a role in shaping landscapes and influencing ecosystems. Additionally, they provide valuable insights into past climate conditions.

How much of Earth's fresh water is in Glaciers?

there is 45 million gallons of fresh water in glaciers

What phase is water in if it is found as a glacier?

If water is found as a glacier, it is in the solid phase. Glaciers are massive sheets of ice formed from compressed snow over many years.

Where do glaciers grow and how do they grow?

Glaciers usually grow in Alaska. Though they are found in mountain ranges. The weirdest part is glaciers can grow in every single continent but, Australia. In the tropics glaciers occur only on high mountains.

What types of valleys do glaciers form?

Glaciers can form U-shaped valleys through the process of erosion, where ice scours and scoops out the landscape. When the glacier retreats, it leaves behind a distinctive valley with steep sides and a wide, flat bottom. These valleys are typically found in mountainous regions.

How do glaciers make valleys?

The glaciers rubs against the land form which changes the land form into a U shape valley this works because the ice is so packed it pushes any land as in dirt sand and minerals out the way creating the valley

Are there glaciers in lake superior?

No, there are no glaciers in Lake Superior. However, glaciers CREATED Lake Superior, in fact, all of the Great Lakes. Lake Superior may have large floes of ice in winter.

How does glacial debris end up at the bottom of a glacier?

Glacial debris gets incorporated into the glacier as it flows over the landscape, picking up rocks, sediment, and other materials. These materials are then transported within the glacier towards its base due to the movement of the ice. Once the glacier reaches a warmer area or melts, the debris is deposited on the ground or in bodies of water, leaving behind evidence of the glacier's path.

What are created when two valley glaciers join together?

When two valley glaciers join together, they form a larger glacier known as a piedmont glacier. This occurs when the two glaciers meet at the base of adjacent valleys and merge into a single mass of ice that spreads outwards. Piedmont glaciers are common in regions with mountainous terrain and abundant snowfall.

What is the best source of information about glaciers?

The best source of information about glaciers would be scientific publications and reports from reputable institutions such as the National Snow and Ice Data Center, the World Glacier Monitoring Service, and the Intergovernmental Panel on Climate Change (IPCC). These sources provide up-to-date and reliable information on glacier research, monitoring, and the impact of climate change on glaciers.

What is the land like in northeast?

The landscape in the northeast is diverse, ranging from coastal areas and beaches to mountains and forests. States like Maine and Vermont have rugged terrain with dense forests, while states like Massachusetts and New Jersey have more urban and suburban areas. Overall, the northeast region offers a mix of natural beauty and developed landscapes.

Where did Glaciers used to be?

Glaciers used to be present in many regions of the world during the last ice age, which ended approximately 11,700 years ago. They covered large parts of North America, Northern Europe, and Asia. Today, glaciers can still be found in locations like Greenland, Antarctica, and high mountain ranges.

Is your father a glacier?

It means you are blocking the TV; please move out of the way. Should be glazier.

What is the proccess by which glaciers make icebergs?

When a glacier flows into the sea, it breaks off chunks of ice at the edge, forming icebergs in a process called calving. The icebergs then float away from the glacier and into the open ocean.

What are tiny black dots that move through glaciers?

The tiny black dots that move through glaciers are likely cryoconite, which are particles of dust, soot, or other impurities that get deposited on the surface of the ice. As the cryoconite absorbs heat from the sun, it melts the surrounding ice, creating dark spots that appear to move as the ice melts and refreezes.

How did the glaciers start?

There will usually be a period of climate change where average temperatures decrease. There are a number of potential causes including Milankovitch cycles which are variations in the orbital eccentricity, axial tilt and precession of the Earth as it orbits the sun. These are thought to have an impact on the climate of the Earth. Also factors such as variations in solar activity and variations in the Earth's albedo (the amount of solar radiation reflected back into space) are thought to play a part in fluctuations in climate.

This can ultimately lead to lower average temperatures and increases in the precipitation of snow which accumulates and undergoes the process of nivation due to repeated freeze-thaw and compaction which ultimately alters the snow into ice. As this snow / neve / glacial ice accumulates over thousands of years it can form large ice sheets that may cover large sections of whole continents.

Do glaciers make lakes?

no. mountains are formed by volcanism or plate tectonics - upwellings of magma that push the earth upward or pressure between tectonic plates which folds the earth into mountain ranges at the boundaries. However, glaciers did gouge out valleys between mountains.

How are icebergs formed and why do they float?

Icebergs are formed when chunks of ice break off from glaciers or ice shelves. They float in water because ice is less dense than liquid water. This is due to the fact that ice takes up more space than the same amount of liquid water, allowing icebergs to displace enough water to stay afloat.

What is bedrock that is scratched by boulders held in the bottom of glaciers is said to be?

Bedrock that is scratched by boulders held in the bottom of glaciers is said to be "polished and striated." This process occurs through glacial abrasion, where the boulders act like giant sandpaper, scraping and smoothing the bedrock as the glacier moves over it.

What are 2 ways glaciers helped shape the northeast?

  1. Glaciers in the Northeast region sculpted the landscape by carving out valleys and fjords as they moved and melted, creating unique geological features like the Finger Lakes in New York and the White Mountains in New Hampshire.
  2. The weight and movement of glaciers reshaped the region's topography, depositing sediment and creating moraines, eskers, and drumlins that influence local soil composition and drainage patterns.

What is glacier movement primarily caused by?

Glacier movement is primarily caused by the force of gravity pulling the ice downhill. As a glacier accumulates snow and ice, the weight of the ice causes it to slowly flow under its own mass. Additionally, meltwater at the base of the glacier can help reduce friction with the underlying bedrock, facilitating movement.

How did glaciers effect Europe's landscape?

Glaciers in Europe sculpted the landscape by eroding valleys, carving out fjords, and depositing large amounts of sediment, shaping the present-day topography. They also helped shape the Great Lakes and other important landforms in the region.
