Which of the following lists the four characteristics a substance must have to be considered a mineral?
Naturally occurring, inorganic, solid, definite chemical composition
Man-made, organic, liquid, variable composition
Naturally occurring, organic, gas, definite chemical composition
Synthetic, inorganic, solid, indefinite composition
The difference between a compound mineral and a native mineral is:
A compound mineral is made of two or more elements, while a native mineral is made of a single element.
A compound mineral is always metallic, while a native mineral is always non-metallic.
A compound mineral is found only in rocks, while a native mineral is found only in soil.
A compound mineral is man-made, while a native mineral is naturally occurring.
Liquid water is not considered a mineral even though ice is because:
liquid water is not a solid, while ice is a solid
liquid water is not naturally occurring
ice is not made of water
liquid water has a different chemical composition than ice
The test that best shows the true color of a mineral is:
streak test
hardness test
luster test
cleavage test
The property of a mineral that describes how light reflects from its surface is called:
luster
hardness
cleavage
streak
The Mohs Scale measures:
the hardness of minerals
the color of minerals
the weight of minerals
the temperature of minerals
A mineral that leaves a white streak and has a hardness of 2 is likely to be:
Gypsum
Quartz
Calcite
Talc
Cleavage and fracture are different in which of the following ways?
Cleavage is the tendency of a mineral to break along flat planes, while fracture is an irregular break.
Cleavage is an irregular break, while fracture is along flat planes.
Cleavage and fracture both refer to the color of a mineral.
Cleavage and fracture both describe how a mineral reacts to acid.
A conchoidal fracture looks like:
a smooth, curved surface similar to the inside of a seashell
a rough, jagged break with sharp edges
a flat, even break along crystal planes
a break with small, granular fragments
The test that uses hydrochloric acid to identify carbonates is:

Some examples of special mineral tests used by mineralogists are:
magnetism, reaction to acid, taste, fluorescence
color, luster, streak, hardness
density, cleavage, fracture, transparency
crystal shape, size, weight, color
An ore is different from a regular mineral because:
An ore contains a valuable substance that can be profitably extracted, while a regular mineral may not.
An ore is always metallic, while a regular mineral is always non-metallic.
An ore is found only on the Earth's surface, while a regular mineral is found underground.
An ore is a man-made material, while a regular mineral is naturally occurring.
The mineral family that makes up about 90% of the earth’s crust is:
Silicates
Carbonates
Oxides
Sulfides
The most common way minerals are obtained from the earth is:
mining
fishing
planting
condensation
Placer deposits are formed by which of the following processes?
The concentration of valuable minerals by mechanical action of water.
The cooling and solidification of magma beneath the Earth's surface.
The accumulation of organic material in swamps and bogs.
The chemical precipitation of minerals from solution.
Native metals such as gold and copper are good electrical conductors because:
they have free electrons that allow easy flow of electricity.
they are always found in pure form in nature.
they do not react with other elements.
they are the most abundant metals on Earth.
Mining shows both wise dominion and potential risk because:
it provides valuable resources but can harm the environment if not managed responsibly.
it always benefits the environment and never causes harm.
it is only risky and has no benefits.
it is unrelated to resource management or environmental impact.
The property of copper that makes it useful for plumbing pipes is:
its resistance to corrosion
its high melting point
its magnetic properties
its transparency
From a Christian worldview, people should use the mineral resources God placed in the earth by:
Using them responsibly as stewards of God's creation.
Exploiting them for personal gain without concern for others.
Ignoring them and leaving them untouched.
Using them only for religious purposes.
Scientists study mineral properties carefully before classifying or using them because:
it helps them identify and use minerals correctly.
it makes minerals look more attractive.
it is required by law for all minerals.
it increases the value of the minerals.
