Do to the force of friction a glacier will start to move down hill once the layer of snow and ice is more than about 30 to 40 meters deep?

Glaciers move downhill due to gravity and the internal deformation of ice. The ice acts like a brittle solid until the thickness exceeds about 50 meters. Pressure on ice deeper than 50 meters causes plastic flow, which causes them to start to move.
They also move through basal sliding in which it slides over terrain, lubricated by the presence of liquid water created from ice that melts under high pressure from frictional heating.

Usually thin till layer laid down by a retreating glacier?
Kame sheet forms thin layers by a retreating glacier.
What is irregular and thin till layer laid down by a retreating glacier?
khame
What part of a glacier moves fastest when glacier moves by internal plastic flow?
the top layer whic is compacted snow and ice which is about 15m deep
Why do large particles in a rock layer cause less friction?
Large particles have less total surface area, so caused less friction then the smaller particles do...!!
Why aren't there many meters in the troposphere?
because it is the layer where airplanes fly
Is it true that due to the force of friction a glacier will start to move downhill once the layer of snow and ice is more than about 30 to 40 meters deep?
False. A glacier will move due to the force of gravity, not friction.
Can a liquid experience friction?
As liquid flows on an inclined surface there will be frictional force between the bottom most layer and the surface of inclined plane. More over there will be a friction between the successive layer of the liquid. This is termed as viscous force.
Can you give a conclusion about friction?
friction is the force resisting the relative motion of solid surfaces,fluid layer,or meterial elements in contact
How snow turns into glacier?
The snow freezes and becomes layer and soon becomes a glacier
What is the pressure causing ice layers to slid over each other called?
Basal slip occurs when the glacier rests on a slope. Pressure causes a small amount of ice at the bottom of the glacier to melt, creating a thin layer of water. This reduces friction enough that the glacier can slide down the slope. Loose soil underneath a glacier can also cause basal slip.

What do you call a force that opposes the motion of one surface as it moves across another?
This is one form of the property called friction. It is not a kinetic force, but opposes a force. It is caused by the interaction between molecules of the interacting surfaces. When motion occurs between surfaces, friction may convert mechanical energy to thermal energy (heating).For some surfaces, notably liquids, it can be much less than others, notably rough solids. There are different types of friction, and rolling friction is usually less than sliding friction. Lubricants are used to reduce friction by adding a layer of smoother or liquid material between surfaces.
What prevents friction between the layer of the pericardium?
pericardial fluid
How one can increase the force of friction?
there are a few different things that come to mind immediately. The most prevalent being changing one or both of the surfaces making contact. for instance, rubber (as in a tire, most often) on clean, dry pavement has a static friction coefficient of 0.9 μs while rubber (again as in a tire) on wet pavement has a static friction coefficient somewhere in the ballpark of 0.25-0.75 μs.the static (and kinetic, for that matter) coefficient of friction varies between almost every pair of materials (some may be close if the surfaces are similar).additionally, the force of friction would increase the greater the mass of the object that the force is being applied to. the force of friction is calculated as follows;Ff = μ · Nwhere Ff is force of friction, μ is the coefficient of static friction, and N is the normal force (normal force is equal to the mass of the object times the acceleration of gravity. the unit of measurement for this value is newtons, and it is simply the weight of the object) Given this equation, you can see that by increasing the mass of the object, you are in effect increasing the frictional force acting on that object.hope this helped!
