*MOH'S HARDNESS SCALE - The hardness of a mineral is the mineral's resistance to scratching. Hardness can be indicated on a scale from 1 to 10 with 1 representing the least hard and 10 the hardest.
*Put in order of hardness:
1. ___________________________ gypsum
2. ___________________________ fluorite
3. ___________________________ talc
4. ___________________________ quartz
5. ___________________________ orthoclase
6. ___________________________ apatite
7. ___________________________ topaz
8. ___________________________ diamond
9. ___________________________ calcite
10. __________________________corundum

A mineral with a higher number can scratch anything beneath it or equal to it in hardness. IF A MINERAL WILL SCRATCH ALL THE MINERALS IN THE SCALE UP TO 4 AND IS SCRATCHED BY APATITE, ITS HARDNESS IS IN BETWEEN _________ AND _________.
Mineral hardness can be estimated by using common objects with a known hardness as follows:
Fingernail 2.5
Penny 3.0
Window glass 5.5
Knife blade 5.5
Steel file 6.5
The mineral shown on Moh's hardness scale that can be scratched with a steel file, but not with a knife blade is ____________________________and has a hardness of _________________.
