People who live in regions that rarely experience snow are likely unaware of the subnivium world. Scientists call it “subnivium,” from the Latin “sub,” meaning below, and “nivis,” for snow. During winter, the subnivium world becomes active and full of life.
As snow falls, it gradually accumulates in layers that compress, forming a snowpack. When the snowpack reaches about seven inches, the subnivium world appears. This thick snowpack acts like a natural igloo, providing insulation for everything underneath. Regardless of the air temperature outside, the ground beneath the snowpack stays about 1°C above freezing.
The subnivium world isn’t dormant. Bacteria and fungi decompose plant material, consuming oxygen and releasing carbon dioxide. This process, called soil respiration, makes the soil rich in carbon. In the spring, plants have the nutrients they need to grow. The soil also hosts springtails, centipedes, rove beetles, and other arthropods that move around, feed, and reproduce. These creatures become food for higher animals like shrews, moles, ground squirrels, pikas, and marmots.
The subnivium world isn’t a result of luck. Just like the environment above the snow, it exists because of careful natural engineering. The laws of thermodynamics tell us that without energy input, systems tend toward disorder, a state called entropy. Recognizing the engineering principles involved in the subnivium world shows the Creator’s intelligence and deliberate design, adding to the evidence for God’s existence.
