Which of the following statements about minerals is FALSE?
Minerals have a crystalline structure.
Humans can create minerals to suit specific needs.
Minerals are inorganic materials.
Minerals cannot be liquids or gases.
The image is pyrite. What could be used to classify this structure as a mineral rather than a rock?
It was initially molten and has now cooled
It melts at a higher temperature than rock
It has a crystalline structure and a pure elemental composition
It has multiple elemental compositions that came together to form pyrite.
Your group is to identify a mineral. You noticed that your mineral fell apart into thin layers or sheets. What mineral did you have?
gypsum
mica
quartz
talc
What is the best explanation of the main difference between a rock and a mineral?
Minerals are organic; rocks are inorganic
Rocs are naturally occurring; minerals do not occur naturally.
Rocks are crystalline solids; minerals are not crystalline solids.
Minerals have a definite chemical composition; rocks do not have a definite chemical composition
You and your group have been handed five mineral samples to identify. First, you sort the minerals by color. All five minerals are white! Two are glassy and transparent. You have identified two minerals. They are calcite and quartz. Compare and contrast the properties of the two minerals. How can you EASILY tell them apart?
check if one is shiny
check if one scratches glass
check to see which has bands
check to see if one splits into sheets
You and your science group have been handed five mineral samples to identify. First you sort the minerals by color. All but one is white. The non-white mineral is banded and has many colors. What is this mineral?
Feldspar
Fluorite
Mica
Quartz
The Duluth Complex, one fo the world's largest undeveleoped mineral deposits, stretches across northeastern Minnesota and contains an estimated 4.4 billion tons of valuable metallic minerals.
