Gold, petroleum and coal are examples of ____________.
Gold, petroleum and coal are examples of ____________.
The correct option is D Minerals
B. Minerals
Native gold is an element and a mineral. It is highly prized
by people because of its attractive color, resistance to tarnish, and its many
special properties - some of which are unique to gold. Its rarity, usefulness,
and desirability make it command a high price.
The term mineral is sometimes
used in reference to natural earth (non-living) resources, and thus, in a
non-scientific sense, petroleum resources are mineral resources and deposits of
petroleum are often called mineral deposits. Coal, sands, gravel, and such
would also be considered a mineral resource in this particular usage, even
though coal is a rock, not a mineral, and the others are mixes of multiple
minerals and/or rocks and not, strictly speaking, minerals.
