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.

What general name for the rising and falling of a sea levels in response to the forces exerted by the moon and sun?

Tides, sometimes called lunar tides.

You can have

  • high tides
  • low tides
  • spring tides
  • neap tides
  • Proxigean spring tides

For more information see the link below
The Tidal Range, the gravitational effect of the moon on the oceans.

What can you tell about the rate of speed of different parts of the glacier?

usually you would place a couple of stakes across the glacier and over time you would see them move. so it would be the distance that the moved over the time it took. usually the stakes towards the middle will move the fastest because they are less affected by friction. you could also just clock it with a speed gun....

How much of the Lambert glacier is covered underwater?

Only 10 percent of the iceberg are above water. That means 90 percent of the iceberg are underwater.

How did glaciers affect water levels in the ocean?

Periods of glaciation cause sea levels to drop, because that water gets locked up in ice on land.

What type of mass movement caused by gravity?

Any mass moves in the direction of the vector sum of all the forces acting on it,

with an acceleration numerically equal to the magnitude of the sum of the forces

divided by its mass.

On or near the Earth's surface, gravity is always one of the forces.

Can glaciers erode rock and deposit sediment?

Yes, wind and wave action can cause significant weathering to the glacier along the water line, eventually causing large chunks to break off and fall into the ocean to become icebergs.

How would you expect a valley to look after a glacier has passed through it?

Oh, scenic. Beautiful. Sloping, with all of the trees and stuff. Pastoral.

That describes the valley I'm thinking about.

If you resubmit this question with more detail, your odds of getting a "good answer" are much higher. Just sayin'.

What are 3 landforms created by glacier?

a glacier is ice. ice forms a landform called a mouth of a river

Which country can you find glaciers?

Glaciers can be found in countries like Norway, Iceland, Canada, the United States (Alaska), and New Zealand.

What is a ridge at the farthest point reached by a glacier?

This is known as a Lateral moraine.

Please see the related link for more information.

How do you describe the landscape made by alpine glaciers compared to the landscape by continental glaciers?

Alpine glaciers leave behind U-shaped valleys, deep, high-altitude lakes and cliffs. Continental glaciers flow outwards scraping the landscape clean, making fairly flat lands and lakes

What feature does a waterfall leave behind?

Waterfalls form when there is a sudden interruption in the course of a river. They may result from erosion by ice, changes in sea level and earth movements. However, many waterfalls form when rivers meet a band of softer, less resistant rock after flowing over a relatively hard, resistant rock. The underlying softer rock is worn away more quickly, and the harder rock is undercut. In time the overlaying harder rock will become unsupported and will collapse. After its collapse, some of the rock will be swirled around by the river, especially during times of high discharge, to form a deep plunge pool. This process is likely to be repeated many times, causing the waterfall to retreat upstream and leave a steep-sided gorge.

Why do glaciers in Africa exist?

,yes, during the time in pangea there the weather must have been cold and there were ice glacier deposites found there

What is the name of smooth egged shaped hill deposited by a glacier?

Roche moutonnee: An Alpine term for a rock knob with one smooth side and one steep side, produced by glacial plucking. They are named "fleecy rocks" in French because they often look like a field of giant stone sheep. Roche moutonnee formations are sometimes called "sheepbacks" in English.

What are Fjords glaciers?

A Fjord is a breed of horse from Norway. They can be found in most places but might be rare in hotter countries as they are specially adapted for cold weather and challenging terrain.

How can you stop glacier erosion?

1. Recycle (no help or affect)(great idea for planet though!)

2. Ride your bike to close places instead of a car (If we banned all cars the change is less then 0.00001% over 50 years)

3. Shop online... It helps by not polluting the air by a car (Serious?)

Glacial Erosion has been happening for millions of years. This is a very natural cycle. The past 6000 years of steady warmth has accelerated this somewhat in the North and reduced the issue in the Southern Hemisphere. Science data has shown that the net overall change in glacial ice is about 0. The overall transfer of ice from North to south is cyclic as theorized by Milankovich and proven with Vostok data. Under the current theories, this transfer is normal and the cycle reverses every 50K years or so. The complete 100K year cycle that shows nothing unusual is occurring is available on many sites. The Vostok ice data is what you want to look at. NASA is also seeing cooling of our oceans which disagrees with Doc. Hansen and other extremist viewpoints. Nothing hew here folks..... The planet is doing what it is supposed to do.

When a glacier retreatsis it moving backwards?

A glacier is a 'river' of ice. In cold places where precipitation falls as snow rather than rain, the snow thickness builds up and up and forms a field of ice as its compacts.

Masses of ice are not solid but flow very slowly down hill under the force of gravity. This ice flow is called a glacier.

Glaciers flow down hill and as they do so it gets warmer and the ice at the tip of the glacier melts (they turn into rivers of water).

If the climate is cold then this melting happens less fast than the snow is supplying new ice at the top and the bottom of the glacier will advance (the glacier gets longer). If the climate is warming then the melting happens faster than the snow is supplying new ice and the bottom of the glacier will retreat back up towards the snow/ice field (the glacier gets shorter)

All of earths glaciers are currently getting shorter - the Glaciers are in retreat. This is because earths climate is getting slightly warmer.

What evidence of glaciers tell us about Pangea?

the evidence is

  • fossil evidence - identical fossils in different continent
  • rock type and structural similarities - found similar rocks on continents on opposite sides
  • study of climate - the heat of the sun
