Does anyone know how a pool of water can form in a glacier if there are no crevasses or streams from the outside to feed the water? There was a question on the state test last year, and I didn't know what the answer was. I've looked everywhere for an answer, but I can't find anything.

This is way outside my areas of expertise, but I would guess they are talking about melt ponds: http://en.wikipedia.org/wiki/Melt_pond

Hi, newbie here to DP :D Wondering if anyone could give some suggestions as to what to study and what books/websites/other resources would be useful? Thanks so much~

As always, I suggest starting on the Dynamic Planet Wiki. There's a lot of great stuff on there as well as links to other external resources that you can use as well. For tests, check out our Dynamic Planet Test Exchange 2014.

I believe that this is possible due to the intense pressures found deep within the glacier caused by the overlying ice. The pressure melts the ice, as "The melting point of ice falls by 0.0072 °C for each additional atm of pressure applied" (Wikipedia). A related phenomenon is recognized in glaciers called "regelation" in which this pressure melted water reforms into ice when the pressure is reduced.

There do not seem to be any major changes in the rules from last year.
