How does the snowfall change to ice?
Snow primarily changes into ice be melting and refreezing. In glaciers, snow is crushed and recrystallizes under pressure.
Glaciers form and grow when the snowfall from one season does not melt and is later covered and compressed into ice by the snowfall what seasons?
This is true
Is the best time to salt a driveway before during or after snowfall?
The best time to salt a driveway is before snowfall if you can anticipate it. This will help prevent ice from forming and make it easier to shovel snow. If you missed salting beforehand, you can salt during snowfall to prevent accumulation and slippery conditions. Salting after snowfall can still be effective in melting existing ice.
How tall is the Columbia ice field?
The Columbia Ice Field is 365 meters high and it can get 7 meters of snowfall each year
Where did the ice made of fresh water in Antarctica come from?
The Ice that forms the galciers and ice pack are from snowfall over many years, which over time and pressure become solid ice.
What is firnification?
Firnification (Snow to ice conversion) • As snow is progressively buried by further snowfall it becomes compacted and eventually metamorphoses into ice. • Key change = air passages are sealed off at a density of ~ 830 kg m-3. • At depth depending on water, temperature, pressure
How has climate change affected the shape of Antarctica in recent decades?
Climate change has led to significant melting of Antarctic ice shelves, resulting in the thinning and retreat of glaciers. This has caused the shape of the Antarctic continent to change, with some areas experiencing increased ice loss and others seeing a rise in ice mass due to snowfall. Overall, Antarctica is losing more ice than it is gaining, which is contributing to rising global sea levels.
Under what circumstances will the front of the glacier advance Retreat Remain history?
Glacial advance and retreat is determined by the balance between the accumulation of snow and the removal of ice by sublimation, melting, and calving (ablation). When the rate of ablation below the snowline equal
What is a large mass of ice and snow forming when the rate of snowfall constantly exceeds the melting rate of snow?
A glacier.
Where does solidification happen in the water cycle?
Solidification involves conversion of water to ice. It happens during snowfall in precipitation.
How thick is the ice in Antarctica and what factors contribute to its thickness?
The ice in Antarctica can be up to several kilometers thick. Factors that contribute to its thickness include snowfall accumulation, compaction of snow into ice over time, and the movement of ice towards the coast.
What is the ice budget?
The ice budget refers to the balance between ice accumulation and ice loss within a glacier or ice sheet over a specific period. It encompasses factors such as snowfall, ice melt, sublimation, and calving events. A positive ice budget indicates more accumulation than loss, leading to glacier growth, while a negative budget suggests more loss than accumulation, resulting in retreat. Monitoring the ice budget is crucial for understanding climate change impacts and sea level rise.
