Which example most clearly shows a connection between natural resources and the built environment?

Canada is a leading producer in gold and diamonds. In 2019, Canadian diamond mines had lower diamond production, which led to a decrease in the value of diamond exports.
Iowa and Illinois are the highest producers of corn in the US. This has contributed to the growth of farmers’ markets and businesses that sell farm equipment in those regions.
Mexico has an abundance of petroleum and crude oil resources. As a result, Mexico is a major exporter of oil and oil products and an important trading partner of the US.
The US is a major producer of coal, a type of rock found deep underground. Much of this coal has been obtained from the Appalachian Mountains in West Virginia, Kentucky, Virginia, and Tennessee.

The most clear example that shows a connection between natural resources and the built environment is the last example about the US being a major producer of coal obtained from the Appalachian Mountains. This example directly highlights the extraction and utilization of a natural resource (coal) from a specific geographic location and its impact on the built environment in those regions.

The example that most clearly shows a connection between natural resources and the built environment is:

The US is a major producer of coal, a type of rock found deep underground. Much of this coal has been obtained from the Appalachian Mountains in West Virginia, Kentucky, Virginia, and Tennessee.

In this example, the natural resource of coal has directly influenced the built environment in the Appalachian region. The extraction and production of coal have led to the establishment of mining towns, infrastructure, transportation networks, and coal processing facilities. The built environment in these regions is shaped by the presence and utilization of coal resources.
