In the fruit and vegetable product industry, chlorine is commonly used to remove microbes such as bacteria and mold from produce. In the home, a water wash, either with or without the help of a produce brush, is typically used to clean fruits and vegetables.
57 ALPINE ZONE The alpine zone occurs in high mountain areas where the mean annual precipitation is above 41 inches and the RET is the lowest in the state (Figure 7.6). These areas occur above the upper timber line. The vegeta-tion consists mainly of small cushion plants on rocky slopes.
Near the equilibrium line on some glaciers, a superimposed ice zone develops. This zone is where meltwater refreezes as a cold layer in the glacier, forming a continuous mass of ice. The wet snow zone is the region where all of the snow deposited since the end of the previous summer has been raised to 0 Â°C.
