*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 _________________.

*Make a list of some of the geologic materials used in the construction of your home:
