Explanation / Answer

All of the above is correct.

Ice is considered to be the best preserver of fossils.Many great mammals like mammoth, dinasours etc were identified and analysed from the remains which were found in antartic region.

The ice also has bubbles of trapped gas that reveals the old volcanic eruptions and gives us an idea about the earth's early atmosphere.

Scientist spend many years exploring the ice caps of poles and other area and have succeded in gatheirng a huge information about the above points.
