Chapter 26 Flashcards
mineral
naturally occurring, inorganic solid with a crystalline form.
streak
color of a mineral in its powdered form.
cleavage
manner in which a mineral breaks along planes of weakness, creating sets f smooth parallel side; determined by the arrangement if atoms in the mineral´s structure.
fracture
manner in which a mineral without cleavage will break, producing uneven, irregular surface
hardness
measure of mineral´s resistance to scratching, described, by Mohs scale of hardness.
magma
molten rock material inside Earth
What is a mineral?
A mineral is a natural occurring, inorganic solid, with a crystalline form.
What are the two most abundant elements that make up earths crust?
Oxygen and Silicon
What does inorganic mean?
Inorganic mean that minerals are materials that are not living.
What does the arrangement of an atom and the bonds between them reflect about a mineral
The way the minerals breaks, how hard it is, and what type of crystal shape it has.
What are all of the ways to identify minerals
Luster, streaks, cleavage, hardness, color, fracture, tenacity, atomic arrangement,
What are the two types of luster
Metallic and Non-Metallic
How does metallic luster reflect lights?
Reflexes very easy like the way metal surface reflects light
How does nonmetallic luster reflect light?
It reflexes like glass
who do you perform a streak test
unglazed, white porcelain tile
