Answer 2

Answer:

There are 6 types of characteristics for rocks and minerals.

They are:  

- Hardness (is a measure of the mineral's resistance to being scratched, The Mohs Hardness scale is how we measure the hardness, for example : 1= Softest  10= Hardest )

- Lustre ( some minerals are shiny and some are dull, lustre means metallic  or non metallic. )

- Color ( Color is a important property of a mineral and  helps identify a mineral but doesn't totally identify it.)  

- Crystal Structure ( Crystal structure is another way to figure out what type of rock or mineral it is. The mineral or rock must have straight edges, flat sides, and regular angles. )

- Streak ( Streak refers to the colour pouder that the mineral leaves after it scratches it. )

- Cleavage and fracture ( Cleavage is a way the mineral breaks and fracture is a breakage is rough and has jagged edges. )
