Coal may be mined in underground mines, typically by machinery that pulls the coal from the seams, and transports it to the surface. Coal is also mined in surface mines by removing the soil and rock on top of the coal, and then using machinery to break the coal from the seams, and move it to storage.
Wood is a renewable resource because trees can be replanted and harvested sustainably. Oil, iron, and coal are non-renewable resources because they are finite and cannot be replenished within a human lifespan.
Mineral resources that can be harvested from the continental shelf include oil, natural gas, sand and gravel, phosphorite, and metallic minerals like manganese and iron. Seafloor mining operations are also being developed to extract rare earth elements and precious metals from certain areas of the continental shelf.
Coal deposits are commonly referred to as coal seams or coal beds. These are layers of coal that are found buried beneath the Earth's surface.
Coal that is still in the ground is referred to as coal seam or coal deposit.
Freshwater cannot be harvested from the ocean because it is obtained from sources such as rivers, lakes, and groundwater reservoirs.

More than 2000 years ago. Theophatrus wrote of simple coal mining more than 270 years before Christ. Cave men may have harvested coal lying at or near the surface.
buckeyes and snowThe states natural resources include: Coal, petroleum, and natural gas.
Coal and natural gas are nonrenewable resources because they are finite and take millions of years to form. Cotton, on the other hand, is a renewable resource as it can be replanted and harvested annually.

Oil is not harvested, crops are harvested. Oil is explored and is normally pumped out of the ground.
While the ocean provides a wealth of resources, certain materials cannot be harvested directly from it. For instance, terrestrial minerals, such as coal and iron ore, are not found in oceanic environments. Additionally, freshwater resources, although present in some oceanic areas through processes like desalination, cannot be directly harvested from the ocean itself. Lastly, organic materials like timber and certain agricultural products are not available from oceanic sources.
