Quizplus · Accepted Answer

The main factor affecting soil maturity in Alaska, or the Arctic in general, is temperature. Cold temperatures slow down the processes of weathering and organic matter decomposition, leading to slower soil development and thus, immature soils. Rainfall does affect soil development, but in cold climates like Alaska's, temperature is a more critical factor.
