Summarise what crystal structure means: A repeating pattern over and over again.

Summarize Figure 1: Has all the characteristics of a mineral

Summarise what a solid means: Has a define volume and shape

# data[].attributes.body
Summarise what inorganic means: A mineral cannot form from materials that were once part of a living thing

# data[].attributes.body
Summarise what naturally occurring means: Formed from the natural world.

Summarize paragraph 1:

The paragraph is saying that each mineral has characteristic properties that can be used to identify it

Summarize Color paragraph:

it's easy to tell the color of a mineral but you can't tell what type of mineral it is just by color

# data[].attributes.body
Summarize Streak paragraph:

Steak is the color of the rocks powder. The streak and the color of the rock can be very different.

Summarize Figure 2:

Just because it is the color of gold doesn't mean it's really gold it could really just be fools gold

Summarize figure 3:

The mineral's streak can be the same or quite different from its color.

Summarise luster

Luster is the term used to tell how light is reflected off a minerals surface.

# data[].attributes.body
Metallic,glassy,waxy,greasy, or pearly submetallic or dull,siky,earthy

Summarize hardness paragraph: MOHs hardness scale depends on if you can scratch a rock with a fingernail, a Steele knife........

Hardness Scale

the way a mineral breaks apart can help to identify it. a mineral that splits easily along flat surface has the property cleavage. whether a mineral has cleavage depends on how the atoms in it's crystals are arranged.

# data[].attributes.body
the crystals of each mineral grow atom to form that minerals crystal structure. Sometimes. The crystal is obvious from the minerals appearance.

# data[].attributes.body
All crystals of the same mineral have the same crystal structure. each mineral also has other characteristic properties.Sulfur has the lowest density.

# data[].attributes.body
Some rocks have special abilities which make them have special properties for example magnetism would be the ability that is the rocks property.

# data[].attributes.body
In figure eight it shows a lot of rock that has the property fluores cence, magnetism, radioactivity, and reaction to acids. Magnetism-attracts certain metals. Fluorescence-shows how some rock glow in ultraviolet light. Reactivity-shows how some rocks reacts chemically to acids. Optical properties-shows how some rocks bends light to produce a double image.
