Final answer:
The key to understanding Von Thünen's model is the relationship between distance to markets and transportation costs. Farmers closer to the market grow more perishable and expensive-to-transport crops, while those farther away specialize in less perishable and cheaper-to-transport crops.
Step-by-step explanation:
The key to understanding Von Thünen's model is the relationship between distance to markets and transportation costs. According to the model, farmers will choose to grow crops that are profitable and can be transported at a lower cost. The closer a farmer is to the market, the more perishable and expensive-to-transport crops they will grow, like dairy and fruits/vegetables. As the distance from the market increases, farmers will specialize in less perishable and cheaper-to-transport crops, such as grains.
