1. Minerals
1.1. properties
1.1.1. color
1.1.2. hardness
1.1.2.1. How had something the minerals is compared to things like glass and copper.
1.1.3. reaction w/acid
1.1.4. transparency
1.1.4.1. How much light can go through an object
1.1.4.1.1. Transparent: light goes through
1.1.4.1.2. Translucent: a little light goes through
1.1.4.1.3. Opaque: no light goes through at all
1.1.5. streak color
1.1.5.1. What color does the rock make when it is scrached
1.1.6. light refraction
1.1.6.1. Light refraction how much light the is being bent
1.1.7. luster
1.1.7.1. Luster is how shinny something is
1.1.7.1.1. Brilliant: it reflects a lot of light
1.1.7.1.2. glassy: reflects somelight
1.1.7.1.3. dull: reflects no light
1.2. Some examples of minerals are calcite, quarts, fluorite, and diamond
1.2.1. Calcite is number 3 on the Mohs scale and does give a reaction when hydrochloric acid is applied to it.
1.2.2. Quarts is number 7 on the Mohs scale and this mineral does not give any reaction when hydrochloric acid is applied to it.
1.2.3. Diamond is number 10 on the Mohs scale and it is the hardiest mineral.
1.2.4. Fluorite in number 4 on the Mohs scale
2. Rocks
2.1. There are thee types of rocks are sedimentary, igneous, and metamorphic.
2.1.1. Sedimentary is formed by a large number of dead plants in swampy areas collect on top of each other and layers of sand pilled on top of that.
2.1.1.1. Examples of Sedimentary are Coal and Limestone. These are Sedimentary because they are lighter than other rock types.
2.1.2. Igneous is formed by the cooling of magma or other wise known as lava.
2.1.2.1. Examples of Igneous ate Granite and Gabbro. These are Igneous because they have crystals that can be seen by the human eye and they inter lock like puzzle pieces.
2.1.3. Metamorphic is formed by high heat and pressure deep with in the earth.
2.1.3.1. Examples of Metamorphic are Gneiss and Phyllite. These are metamorphic because you can see that they have bands that go all the way around the rock so it shows where that the rock has been made but layers of soil or sand compacted together.
