Final answer:
In the Von Thunen model, extensive agriculture occurs at the periphery due to lower transportation costs and the ability to store crops. Crops that are expensive to transport and perishable are produced closer to the market, while crops that are cheaper to transport and can be stored for longer periods are produced farther away.
Step-by-step explanation:
In the Von Thunen model, there is extensive agriculture, such as grain crops and grazing, at the periphery because of the lower transportation costs and the ability to store these crops for longer periods of time. Von Thunen argued that crops that are expensive to transport and perishable, like dairy and vegetables, should be produced closer to the market. On the other hand, crops that are cheaper to transport and can be stored for longer periods, like grain, are produced farther away from the market.
