Using the Mohs scale shown, select the minerals that a steel file with a hardness of 6.5 will NOT scratch.

• Talc, Gypsum, Calcite

• Quartz, Topaz, Corundum

• Fluorite, Apatite, Feldspar

• Feldspar, Quartz, Topaz

Which mineral exhibits fracture?

• 
• 
• 
• 

Select all of the following criteria that must be met to be considered a mineral:

• Consistent chemical composition

• Made of various types of minerals

• Organic

• Inorganic

• Crystalline solid

The accompanying diagram shows a broken crystal of the mineral Pyrite.
The shape of the Pyrite crystal is a direct result of the _________

• The way atoms are arranged inside.

• temperature the crystal formed

• type of surface where the crystal formed

• Glacier erosion that changed the crystal
