Question 4975 Deck General

The correct answer is B) Very Open Pack. Ice concentration is measured in tenths, where 10 tenths represents complete ice coverage and 0 tenths represents no ice at all. A concentration range of 1-3 tenths corresponds to Very Open Pack, which is defined as ice covering 1-3 tenths of the water surface. The other options are incorrect because: A) Close Pack is a higher concentration of 7-8 tenths, C) Open Pack is a medium concentration of 4-6 tenths, and D) Very Close Pack is a very high concentration of 9-10 tenths. Therefore, the 1-3 tenths range matches the definition of Very Open Pack.
