Minerals Quiz

Which of the following characteristics must a substance have in order to be classified as a mineral?

• Naturally occurring and inorganic

• Organic and synthetic

• Liquid and organic

• Synthetic and crystalline

What do the words naturally occurring and inorganic mean? (These are two different things!)

• Naturally occurring means existing in nature without human intervention, and inorganic means something that is not living.

• Naturally occurring means synthetic, and inorganic meaning something that is not living.

• Naturally occurring means man-made, and inorganic refers to substances that are organic.

• Naturally occurring means existing in nature with human intervention, and inorganic refers to substances containing carbon-hydrogen bonds.

Which of the following is a non-example of a mineral and why is it not considered a mineral?

• Ice, because it is not solid at room temperature.

• Coal, because it is organic.

• Quartz, because it is not naturally occurring.

• Diamond, because it does not have a definite chemical composition.

What can these three tests/properties tell you about a mineral to help you to identify it? Hardness, Luster, Cleavage

• They determine the mineral's color

• They help identify the mineral's type

• They measure the mineral's weight

• They indicate the mineral's age

Why would you need to run several tests on a mineral to correctly identify it?

• To ensure accuracy due to similar properties among minerals

• To save time by confirming with one test

• To avoid using advanced equipment

• To reduce the cost of identification

What is the relationship between minerals and rocks?

• Minerals are composed of rocks.

• Rocks are composed of minerals.

• Minerals and rocks are the same.

• Rocks are a type of mineral.

What is the difference between lava and magma?

• Lava is molten rock above the Earth's surface, while magma is molten rock beneath the Earth's surface.

• Lava is molten rock beneath the Earth's surface, while magma is molten rock above the Earth's surface.

• Lava and magma are the same, just different names.

• Lava is solid rock, while magma is liquid rock.

What do the words intrusive and extrusive mean?

• They refer to types of rocks formed from magma.

• They are synonyms for invasive and evasive.

• They describe personality traits.

• They are terms used in cooking techniques.

Explain how intrusive and extrusive igneous rocks differ in their crystal sizes.

• Intrusive rocks have larger crystals due to slow cooling, while extrusive rocks have smaller crystals due to rapid cooling.

• Intrusive rocks have smaller crystals due to rapid cooling, while extrusive rocks have larger crystals due to slow cooling.

• Both intrusive and extrusive rocks have similar crystal sizes.

• Intrusive rocks have no crystals, while extrusive rocks have large crystals.

Pumice and scoria are examples of extrusive igneous rock that contain holes. How did the holes get there?

• The holes were formed by gas bubbles trapped in the lava as it cooled.

• The holes were formed by water erosion after the rock solidified.

• The holes were created by volcanic ash settling on the rock surface.

• The holes were carved out by wind over millions of years.
