Question

Which one of the following types of resources is iron ore?
A). Renewable
B). Biotic
C). Flow
D). Non-renewable

Answer 1

Hint:Rocks and minerals which are rich in iron oxides from which metallic iron can be extracted economically are called iron ores. They can vary in color from dark grey, bright yellow, or deep purple to rusty red.

Complete Answer:
- Option A: Renewable resources are natural resources that can be replenished by replacing the portion depleted by usage and consumption, either by natural reproduction or by other processes in a finite amount of time. For example air, water, agricultural resources, wood, etc. Hence, this is an incorrect option.
- Option B: Biotic resources are resources that are derived from the biosphere like living things. They are also considered renewable resources. For example plants, fossil fuels. Hence, this is an incorrect option.
- Option C: Flow resources are resources that are neither renewable nor non-renewable, and must be used where it occurs and replenishes itself and can only be natural resources. For example solar radiation, winds, biomass, etc. Hence, this is an incorrect option.
- Option D: Non-renewable resources are natural resources. They are also known as finite resources as they cannot be replaced readily by natural means at a quick enough pace to keep up with the consumption. For example fossil fuels, groundwater, metal ores. Iron ore is also a non-renewable resource. Hence, this is the correct option.

So, the correct answer is option D.

Note:Iron ore is a natural resource and is discovered in limited quantities. It is used up quicker than it can be formed again by natural processes. It is a mineral and minerals have definite chemical compositions.
