frozen
they can tell you when the ice froze :$
in October
tell me about mrs.becker in trapped in death cave bill wallace
There are bubbles of air trapped in the ice from the snow which show the % gases from the past
it is less known that there are minerals, like iron, that are trapped in the ice sheet which enter the oceans when ice melt occurs.
Approximately 69% of Earth's freshwater is trapped in ice, mainly in polar ice caps and glaciers. This frozen water is a crucial freshwater resource that helps regulate global climate and sea levels.
In the Polar Ice Caps.
Yes, there is air inside ice. As water freezes air gets trapped inside. (Which is why ice cubes float.) =]
Melting ice works, because the ice sheet is fresh water.
Gases and particles get trapped in ice cores through processes like firn densification and bubble entrapment during the formation of glacier ice. As snow accumulates and gets buried over time, the weight causes air to be compressed and trapped in bubbles within the ice. Particles can also be incorporated into the ice as it forms from the compaction of snow layers, preserving a record of past atmospheric conditions.
