How do glaciers move?

The

icebergs are gigantic, solid "ice" ice. They were around most of the country's history and are responsible for large geographical features on its surface, including large lakes. The glaciers travel miles from their origin and store residues in wide lines of soil.

The question is, how does the solid move like ice? There are rocks, but are sudden and cause only erosion. Rockslides does not flow to miles as the glaciers do. So what is the cause of this glacial movement?

There are several mechanisms in the game. The primary has to deal with the relation between temperature and pressure. The melting point of most of the substances increases with increasing pressure - the atoms pushed more closely become more stable. This is not the case of ice. In the ice, the melting point decreases as the pressure increases.

LED on the bottom of the glaciers is under huge pressure. Some glaciers are through pleasantly deep. By combining these extreme pressures and latent heat coming from the ground itself, part of the ice melts and gives the glaciers above it a neat surface that with a rockabuse. However, this melting process is not reliable. It varies depending on pressure and temperature changes. Therefore, the glaciers move slowly, between the thumb and a few feet a day. The large scattering of the flow of glaciers is caused by the same large variance of pressures and temperatures in the glacier.

Another mechanism is the movements of ice crystals inside the glacier itself. The glacier is faster in the center, where the smallest friction with the surrounding rock is. Small ice particles, even in solid form, move in response to slight changes in pressure and small bundles. The aggregated influence of all these small movements contributes to a significant global effect that drives the glacier forward.

Sometimes glaciers move forward at an unprecedented pace called surge . In 1953, for example, the Glacier of the Himalayan Kutiah moved seven miles in three months.The structural arrangement in the glacier reaches the "overturning point" and causes a cascade of collapse and corresponding flow.
