Question

Which of the following types of resources is iron ore?
A. Renewable
B. Biotic
C. Flow
D. Non renewable
E. None of these

Answer 1

Hint: Ores are non-living components of the earth. Iron ore is a type of mineral resource.
Mineral resources take a very long time to form.

Complete answer:
Iron Ore are the rocks and minerals from which metallic iron is extracted on a commercial scale. The iron ores are rich in iron oxides, from which metallic iron is extracted through blast furnaces and similar heat procedures. The ores vary in color from bright yellow, dark grey, or rusty red to deep purple. They are obtained from the earth through mining. Let us now see which type of resource is iron ore-

A. Renewable resources are those resources which are naturally replaced in the environment. Hence, they are limitless and unending. Iron ore is not renewable as the amount of ore might be replaced by nature but it is an extremely slow process. So, this option is incorrect.
B. Biotic resources are those which are obtained from living things. As iron ore is non-living, and is not derived from any living organism either, it is not a biotic resource. Therefore, this option is also incorrect.
C. Flow resources are those which can be used while it simultaneously gets replaced. Iron ore is not simultaneously replaced when it is mined so it is not a flow resource. Thus, this option is incorrect.
D. Non renewable resources are those resources which once used cannot be easily or quickly replaced by nature. Iron ore deposits take a long time to form, and get used much more rapidly. Thus, iron ore is considered a nonrenewable resource. So, this option is correct.
E. Since non-renewable resource is the correct answer, this option is wrong

Therefore, the correct answer is Option D.

Note: Common iron ores are Magnetite, Hematite, Goethite, Limonite and Siderite.
Biotic resources include animal and plant products as well as fossil fuels like coal and petroleum since they were produced by the remains of living organisms. Flow resources include wind, sunlight and water. These resources are neither renewable nor non-renewable. They are some of the cleanest resources available to us. Renewable resources include geothermal energy, hydropower, bioenergy etc. These can be replaced by nature and are therefore less damaging to the environment when used.
