Hmmm... not geology section... but they don't have one.

Streak is what you get when you scratch it on something else.  Hardness is when you use something to test it.  That leaves fracture and cleavage.  Know what those are?

anonymous · Answer

That still doesnt answer my question:(

e.mccormick · Answer

Well, do you know what fracture and cleavage are in geology?

anonymous · Answer

Im confused about it though

e.mccormick · Answer

When you brake a mineral, any mineral, it is going to tent to do one of two things.  Break on clean lines or follow curves.  The clean lines make nice shapes.  The curves make odd lumps.

So, which of those is the picture showing?  Nice shapes or odd lumps?

anonymous · Answer
