Chapter 11: The Agricultural Core

The Agricultural core is located in the Midwest and the Bay Area is located in the West coast. The West Coast includes California, Oregon, and Washington.

The Soil type in the Bay Area does not include the two types of soils, mollisols and alfisols, found in the Agricultural Core. The main reason why the Bay Area does not include mollisols and alfisols is because the climate does not accomodate to form them. There are 5 soil types in the Bay Area. The 5 soil types have been defined as A, B, C, D and E by the National Earthquake Hazards Reduction Program. They include unweathered intrusive igneous rock, volcanics and Mesozoic bedrock, sandstone, mudstone, limestone and artificial fill.
