Crystals and Minerals

                              Crystals & Minerlas

Minerals  is inorganic solid that occurs naturally in the lithosphere, mostly come from the volcanoes and the colors of the minerals are different also some minerals are hardness and some are not. The minerals has to types of luster are metallic and not metallic, some of the minerals are cleavage that is broken evenly and fracture that are broken unevenly. Minerals is a composition of chemicals.

Mineral Properties-

• Luster: Metallic, Non-metallic.

• Color: The color that had the mineral.

• Hardness: Hard.

• cleavage: Broken evenly.

• composition: Chemicals.

• Fracture: Broken unevenly.

• Streak: Power.

• Other properties: Magnetic, shape.

                         Rocks Types

1. Rock Cycle

The rock cycle started with the molten rock that made up the early surface of planet Earth.
When the lava is going outside the lava start to be cold for the weathering and erosion.The lava become together that is call solification then the rock become into  Igneous rock.Igenous rock break down on the surface and move to other place by erosion and it becomes into small pieces of rock that is call sediments. The sediments take new place and they push together that is called compaction then glue together that is call cementation by those process become sedimentary rock.Sedimentary rock gets heated by hot temperature and pressure then it becomes a Metaphoric rock. Metaphoric rock melts by hot temperature and become lava.

2.Rocks - Vocabulary
 
Metamorphic rock- Forms by heat and pressure.

Magma/Lava- Molten rock expelled by a volcano.










Soldification -Liquid that turns into solid.









Igneous rock- Element that formed by lava that is cool by solidification.











Weathering- Breaking down of rocks










Erosion- The wearing away of rocks and other deposits
 on the earth's surface by the action of water










 
Sediment- Small pieces of rock.









 
Compaction- Push together.









 
Cementation- Glue together.












 
Sedimentary rock- Small pieces of rock that are together and glue together.
