Rocks and Minerals (Mrs. Carroll)

Front

Why are brick, steel, and glass not classified as minerals?

Back

They are not classified as minerals because they are not naturally occurring.

Front

Why is coal not considered a mineral?

Back

Coal is not a mineral because it comes from organic materials and does not have a crystalline structure.

Front

Why is Quartz considered a mineral?

Back

Quartz is a mineral because it is inorganic and has a crystalline structure.

Front

Differences between rocks and minerals?

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition formed by natural processes and rock is made of different minerals.

Front

If you have Mineral A with a hardness of 3 and Mineral B with a hardness of 7, which would you use in building materials?

Back

mineral B because it is harder

Front

Minerals that break along smooth, flat surfaces have...

Back

Cleavage

Front

You rub a mineral on an unglazed porcelain tile and notice that it leaves a colored line. This is the true color of the mineral in powder form. Which mineral property is observed in this situation?

Back

Streak

Front

Students in Earth science were conducting an investigation to collect data on the characteristics of minerals. The diagram below shows three minerals undergoing physical tests, A, B, and C. Which tests are most useful for determining the type of mineral? Options: Test A-cleavage; Test B-streak; Test C–hardness, Test A-cleavage; Test B-hardness; Test C–streak, Test A-streak; Test B-cleavage; Test C-hardness, Test A-streak; Test B-hardness; Test C-cleavage.

Back

Test A-cleavage; Test B-streak; Test C–hardness

Front

How do minerals contribute to rock composition?

Back

Rocks are defined by mineral composition and texture.

Front

Trickum Middle School 6th grade students are taking a field trip to the Chattanooga river to take water samples. They noticed that rocks from three different locations had the same rocks but different minerals. How can students determine the type of mineral that contributed to the formation of rocks?

Back

Students can set up various tests to observe the different properties of the minerals because minerals have different properties.
