Do now

DO NOW

  • 1. Which group of planets have solid, rocky surfaces?

  • 2. Which object is a “dirty snowball” made of rock, dust and ice, that orbits the sun?

  • 3. What are the bowl shaped areas on the moon called?


Rocks and minerals

GOAL

  • To be able to distinguish between a rock and a mineral

  • To know the characteristics used to identify rocks and minerals


Rocks vs minerals

Rock

Hard substance made of one or more minerals

Rocks vs. Minerals


Rocks vs minerals1

Mineral

Occurs in nature

Solid

Definite chemical structure

Crystal shape

Rocks vs. Minerals

Rocks vs minerals2

Color

DEF: observed coloration

DETERMINED BY:

Look at mineral

Not always reliable

Rocks vs. Minerals


Rocks vs minerals3

Luster

DEF: way it reflects light off its surface

DETERMINED BY:

Observe mineral

Metallic or nonmetallic

Rocks vs. Minerals


Rocks vs minerals4

Hardness

DEF: ability to resist being scratched

DETERMINED BY:

Rub against other minerals on hardness scale

Rub on glass, steel nail or penny

Rocks vs. Minerals

Streak

DEF: color of powder scraped off

DETERMINED BY:

Rub on a porcelain tile

Rocks vs. Minerals


Rocks vs minerals6

Density

DEF: number of particles in a space

DETERMINED BY:

Mass / volume

Never changes for a mineral

Rocks vs. Minerals


Rocks vs minerals7

Crystal Shape

DEF: shape of atoms in mineral when formed

DETERMINED BY:

Look at small bits of mineral

Rocks vs. Minerals


Crystal shapes

Crystal Shapes

Cleavage or Fracture

DEF: how mineral breaks (layers, jagged, smooth)

DETERMINED BY:

Break mineral (hammer or hands)
