Properties of Minerals by Anthony Ferradino

Group 5 crystal system

the crystals of each mineral grow atom to form that minerals crystal structure. Sometimes. The crystal is obvious from the minerals appearance.

Group 6:Summarize figure 8:

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.

Summarize paragraph 1:

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

Summarize special properties group 6

2014-05-05 13:15:41 UTC

Some rocks have special abilities which make them have special properties for example magnetism would be the ability that is the rocks property.

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

group 5 cleavage and fracture.

2014-05-05 13:17:08 UTC

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.

Summarise luster

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

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

Group 2

2014-05-05 13:21:22 UTC

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 Streak paragraph:

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

Group 2

2014-05-05 13:23:24 UTC

Summarize figure 3:

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

Group 5 summarize Figure 6

2014-05-05 13:24:06 UTC

All crystals of the same mineral have the same crystal structure. each mineral also has other characteristic properties.Sulfur has the lowest density.
