COLOR
S THE VISUAL PERCEPTUAL PROPERTY CORRESPONDING IN HUMANS.
MAGMA
IS A MIXTURE OF MOLTEN ROCKS AND PRIMARILY ELEMENTS ARE SILICON, OXYGEN, ALUMINUM, IRON CALCIUM, SODIUM, POTASSIUM AND MAGNESIUM.
SPECIFIC GRAVITY
REFERS TO THE RATIO OF THE WEIGHT OF A MINERAL TO THE WEIGHT OF AN EQUAL WATER.
DUCTILITY
ABILITY OF MINERALS TO BE DRAWN INTO FINE WIRES.
ORE
REFERS TO THE TYPE OF ROCK THAT CONTAINS USEFUL METALLIC MINERALS LIKE HEMATITE (MINED FOR IRON) AND GALENA (MINED FOR LEAD), THAT CAN BE MINED FOR A PROFIT.
