Abiotic Factors

If you aren't familiar with  abiotic factors, they are non-living characteristics that affect a biome.  The Pacific Ocean provides the Northwestern Coniferous Forest with abiotic factors such as mild temperatures and lots of rainfall.  The majority of precipitation occurs in the spring, winter, and fall.  The summer however recieves the least amount of rainfall and is usually very dry.  This biome is very rocky and because of that, plus the abundant rainfall, this forest has very acidic soil.  When rainfall occurs, it dissolves the sediment, or rock, under the soil, making the soil very acidic.
