Question

Quizplus · Accepted Answer

Glacial ice is indeed a metamorphic version of snow and firn, as it undergoes a process of compaction and recrystallization over time.

Answer: D
 Firn is not freshly fallen snow, but rather compacted snow that has survived one melting season and undergone some degree of recrystallization. It is typically found below the snow surface, rather than on top of it.

The other choices are not correctly matched: crevasses are vertical cracks, not horizontal (A), ice regelation refers to the process of ice crystals merging, rather than melting and refreezing (B), and englacial refers to features and processes that occur within the glacier, rather than on its surface (E).
