heat

how some mineral break along smooth .
scratch test
where you scratch an rock with finger nail or penny to see if its strong
rocks
a naturally formed by the combination of minerals and other natural materials
minerals
a solid naturally form by substance that always has the same composition and the same properties
sedimentary
rock formed by compact sediment
igneous
rock formed by magma or lava
metamorphic
rock formed by an existing rock heat and pressure cause the minerals to form new combinations or new crystals
