Welcome to CoreFacts, where we're always short on time, but
big on science. I'm Steve Sobieszczyk. Today's question is a good one.
Is glacier ice colder than regular ice?
No - indeed, all of the physical, thermal and electrical
properties of "regular icebox ice" and glacier ice are identical:
density, viscosity, heat of fusion, latent heat, heat capacity, thermal
conductivity, and absorption. The few small differences in characteristics are
solely due to grain size differences. It's worth noting that high pressure
forms of ice with different properties have been produced in laboratory
experiments, but none occur naturally on earth, not even at the base of the
Antarctic or Greenland ice sheets.
And now you know. Join us every weekday for a new CoreFact.
If you're looking for more in-depth science coverage, please check out the USGS
CoreCast at usgs.gov/corecast. To have your own question potentially featured
on the air, send it to corefacts@usgs.gov
or leave a voicemail with us at 703-648-5600; however do remember that this is
a long distance charge, so long distance fees do apply.
The USGS CoreFacts is a product of the U.S. Geological
Survey, Department of the Interior.
