What happens when a glacier gains more snow mass than it loses it over a period of many years?
When a glacier gains more snow mass than it loses over many years, it will advance and grow in size. This can result in the glacier moving further down its valley or expanding its coverage area. It can also lead to an increase in ice thickness and volume.
What kind of glacier is Vatnajokull Glacier?
Vatnajökull Glacier is an ice cap glacier located in Iceland. It is the largest glacier in Europe by volume and covers an area of around 8,100 square kilometers. Vatnajökull is a temperate glacier, meaning it has a mixture of ice at its base and can flow due to meltwater lubricating its movement.
By how much did Peyto glacier change since the past century?
It is estimated that Peyto Glacier has lost approximately 70% of its volume over the last century due to climate change. This loss is evident in the retreat of the glacier's terminus and reduction in its surface area.
Mass of ice and rock?
The mass of ice is typically less dense than rock, so ice typically has a lower mass compared to an equal volume of rock. The exact mass of ice and rock would depend on the volume and density of each material.
Does an ice cube melt quicker as it gets smaller?
Melting of an ice cube mainly depends on the temperature of surrounding. If the larger ice cube is put at 50 degrees Celsius and small one at 25 degree Celsius the large ice cube will melt faster than the smaller one. Ice cube draws energy from the surrounding which causes it to melt and so temperature of surrounding is very important
What happens when an ice cube changes into water?
It gets warmer, has a lesser volume. It is called melting.

What happens to a glacier when they get very heavy?
The density of ice at 0°C is 0.9167 g/cm³. The density increases slightly at lower temperatures. Therefore, the volume and temperature of the glacier is needed in order to calculate the exact weight.
What change would occur in a glacier if average annual temperature rose and the precipitation decreased?
The glacier would retreat. The rise in temperature would cause the glacier itself to start melting, and in addition, would lower the amount of precipitation in the form of snow at the top of the glacier. It would be rain instead. Lowering the precipitation would cause less ice formation as well and would also contribute to the glacier retreating.

What would have the greatest effect on sea level a melting glacier or a melting iceberg?
Glaciers. Ice bergs would have very little impact on ocean level, beyond thermal contraction from heat dissipation. The reason is that ice bergs, like boats, already displace a volume of water equal to their weight. Glaciers predominantly rest above the ocean surface, and their melt water runoff entirely increases the ocean volume.
What happens to sea level as a glacier melts?
As a glacier melts, the melted water flows into the ocean, increasing the volume of water and causing sea levels to rise. This process is a significant contributor to global sea level rise, which has the potential to impact coastal areas and communities around the world.
Do samples with same volume melting point and shape have same composition?
The volume and shape are not important for the chemical composition; the melting point can be a serious indication but it is not an absolute criterion.
Is the downward cutting force of ice in a glacier a function of volume?
Yes, the downward cutting force of ice in a glacier is influenced by factors such as volume, thickness, and velocity of the ice flow. A larger volume of ice can exert more pressure and cutting force on the underlying rock, aiding in the glacial erosion process.
What occurs when a liquid becomes a solid?
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed but the bonds between molecules are weakened.
By how much did Peyto glacier change since the past century?
It is estimated that Peyto Glacier has lost approximately 70% of its volume over the last century due to climate change. This loss is evident in the retreat of the glacier's terminus and reduction in its surface area.
What happens to the volume of a cylinder if the height is doubled?
Volume doubles
