The von Thunen model has weaknesses because it does not allow for things like roads or railroads that make it easier to transport goods over long distances. He also does not anticipate things like refrigerated transport that would allow even perishable things to be transported over long distances. Hope this helps or answers your question
Answer: The map projections represent simplified versions of the Earth, or other space objects. While they are made to give us the best possible representation of what is depicted on them, they are still too small, and too simplified, to be able to depict the object as it really is in the nature. As one of the biggest problems is balancing the form and size of the map, with the practical aspect of its usage, and the real shapes and forms, they exhibit distortions. The distortions tend to be large with the increase of latitude, while the lower latitudes have little to no distortions.
Because it shows the ages of the population, so we can see the parts of the place with the population that can and can't work.
Now, the way these maps show social information is: because they point out the demographical distribution about a specific sub-group in the population, its age, and its growth.
And finally, the way these maps provide environmental information is: because they allow us to see the environment of certain zones inside the map territory.
