Question

Which type of resource is iron ore?
A.Renewable
B.Biotic
C.Flow
D.Non renewable

Answer 1

Hint: Iron ores are those minerals and rocks that are rich in iron oxides. Metallic iron can be economically extracted from iron ores. Iron ores vary in color from bright yellow, rusty red, dark grey or deep purple.

Complete answer:
Non- renewable resources are naturally found on earth. They are those natural resources that after their consumption cannot be readily replaced or replenished at the same speed or pace at which they are consumed. The development of these resources takes millions of years. Some of the examples of non renewable resources are metal ores, groundwater, fossil fuels. Iron ore is a metal ore, this is a non- renewable resource. Iron ore is a mineral that yields metallic iron when it is heated in presence of a reductant. The primary source of iron for iron and steel industries of the world is iron ore. Steel is used to make beans that are used in buildings, furniture, automobiles, tools, bicycles, ships and many more items. Major Iron ore deposits of the earth that having formed over 1.8 billion years ago have their deposits in rocks. Sedimentary rocks are the most important iron ore deposits of the earth.Iron ore is a nonrenewable resource.

 Hence, the correct answer is option (D).

Note: Iron ore is one of the natural non renewable resources that is discovered in limited quantities. The rate of the usage of iron ore is much greater than the rate of its renewal by the natural processes.
