- the arrangement of the atoms of the minerals
- how will minerals differ if they have the same units arranged in different patterns?
- one mineral will have some physical properties different from the other
- why do diamond and graphite have different physical properties, even though they are composed entirely of the element carvon?
- the mienrals have different arrangement sof carbon atoms

- they contain silicon and oxygen
- the hardness of a mineral is due to
- the internal arrangement of its atoms
- why do igneous rocks have different textures?
- bc of where they form
- how do igneous rocks form?
- from solidification of liquid magma or lava
- what does the cooling rate of magma dtermine?
- the crystal size of the igenous rock
- intrusive
- large crystals
- how do you get intrusive rocks?
- if the magma cools deep underground
