A. The map shows the political boundaries of different US states.
B. Wisconsin
C. Dairy farms are situated close to the Great Lakes.
D. Land is allocated for corn cultivation and the growth of nutritious grasses.
E. Vegetation and precipitation
Explanation:
A. The map includes the political borders of the states within the US as well as the mainland. Politically, boundaries refer to the imaginary lines that distinguish between multiple political entities. The majority of the outlines are shaped geometrically, often aligning with specific longitudes or latitudes. For instance, Colorado's border spans from 37° N to 41° N.
B. According to the map, Wisconsin exhibits the highest concentration of dairy farms compared to other states, earning the title of "America’s Dairyland" for its leading dairy production in the US. This high density of dairy farms in Wisconsin can be attributed to its proximity to the Great Lakes, favorable climate, growing conditions, availability of quality feed, and excellent dairy cattle breeds.
C. A noticeable pattern presented in the map is that numerous dairy farms are located in the vicinity of the Great Lakes in the northeastern US. This abundance of dairy farms is linked to optimal weather conditions that favor dairy farming, plus the availability of nutritious crops like alfalfa and corn, which serve as feed and contribute to successful commercial dairy operations in the area.
D. A prominent land-use trend associated with dairy farms includes the allocation of expansive areas for the cultivation of corn and nutritious alfalfa grass. Previously, these areas were used for temperate wheat farming. However, the rise of commercial dairy farming has prompted extensive agriculture methods, dedicating large tracts of land to corn and alfalfa production. The application of fertilizers and machinery is prevalent, resulting in high overall farm yields, although the yield per land unit remains low.
E. Two geographical attributes absent from the map that reinforce the observed patterns of dairy farming are:
- Vegetation - The temperate grasslands (Prairies) in these areas provide ample opportunities for growing fodder grass.
- Precipitation - These regions benefit from abundant rainfall sourced from the nearby freshwater lakes, crucial for animal feed cultivation.
