How explorers survived by covering themselves with snow on failed Arctic expedition.

Expert Solution & Answer

Answer to Problem 12Q

Solution:

Snow acts as an insulator.

Explanation of Solution

Explorers survived the failed Arctic expedition by covering themselves with snow because snow acts as an insulation. It does not allow body heat to escape. Also, it does not allow the outside cold temperature to reach the body just like in an igloo.
