BC: GO ROCKS! | 100% | WHAT IT DO DR. T | A+

FC: By: Mitchell Nowacki and Victor Griffin | GO ROCKS! | Rocks and Minerals!!!

1: The Three type's of rocks.

2: How is it formed? - When existing rocks are formed How can it be transformed? - By pressure, heat, and chemical processes. | Metamorphic rocks

3: GO ROCKS | Examples: Gnesis, Marble, Slate, Hornfels, Schist, and Amphibolite.

4: Sedimentary Rocks: How is it formed? - Sediment deposits are compressed and hardened. How can it be transformed? - Erosion, deposition, and cementation.

5: Examples: - Sandstone, Coal, Rock Salt, Shale and Limestone.

6: Igneous Rocks: How is it formed? - When magma cools and hardens. How it can be transformed? - By melting and cooling

7: Examples: Granite, Diorite, Peridotite, Gabbro, Obsidian, Tuff and Basalt

8: Silicate: Chemical composition and structure - Contains a combination of Silicon and Oxygen

9: Characteristics: - they form chains, sheets and frameworks and bond with other cations to form silicate minerals

10: Non-Silicate Minerals: Chemical composition and structure: - Crystalline structures for non-silicate minerals are hexagonal prisms and irregular masses. - Oxides, Sulfides, Sulfates, Halides, and Carbonates are the five major groups of non-silicate minerals.

11: Major Characteristics: - Unrestricted range of colors, shapes, and sizes. - Have salt like structures.

12: Solidification of a Melt: How it occurs: - it forms as heat, energy is added to rocks, causing the atoms in the constituent minerals to break their bonds and begin to move freely.

13: How scientists use process to grow synthetic minerals: - Powdered material is heated to a molten state and manipulated to solidify to a crystalline form, and production from a solution, in which the required aluminum oxide and chromium are dissolved in another material and manipulated to precipitate into crystalline form.

14: Precipitation from solution: How it occurs: - During chemical reactions, precipitation may occur if an insoluble substance is introduced into a solution and the density happens to be greater. (settling or sedimentation are examples)

15: How do scientists use this process to grow synthetic minerals: - to make pigments or to remove salt from water in water treatment. | propionic acid

16: Solid state diffusion: How does it occur: - It occurs by the movement and transport of atoms throughout a solid.

17: GO ROCKS | How do scientist use it: - to molecularly bond baron.
