Mineral Chemistry

Why do you need to run several tests before you can identify a mineral with 100 percent certainty?

• Minerals all have the same chemical structure

• Many minerals share physical properties in common

• Minerals' physical properties can change very quickly

• A mineral can only be subjected to a few tests before it degrades

How do minerals form?

• When magma heats up, minerals boil to the top

• When magma heats up water, minerals cool it down

• When magma cools down, its molecules form crystals

• When magma is still in a volcano, it is full of minerals

What is a mineral?

• A small part that makes up a nucleus of an atom

• An unnatural element that is always liquid

• Any gas that is found on the Periodic Table

• A natural occurring element that is not a plant or animal

Where does table salt come from?

• It is formed by flowing magma

• It is left behind after a volcano erupts

• It is formed by freezing water

• It is left behind as a solution when water evaporates

What tool would you need discover whether a mineral has fracture?

• A hammer

• A file

• A grinder

• A harder mineral
