  1. Properties and Changes Rocks and Minerals

  2. Physical Property • Can be observed or measured to describe matter.

  3. Physical Properties of Matter • Strength • Hardness • Flexibility • Ability to conduct heat • Ability to conduct electricity • Ability to be attracted by magnets • Reactions to water and fire

  4. Strength • Ability to resist being moved or broken by force.

  5. Hardness • A measure of how resistant solid matter is to permanent shapes when a force is applied.

  6. Flexibility • Capable of bending without breaking.

  7. Conduct • A channel in which something travels/moves through.

  8. Reaction • Forming or breaking chemical bonds between atoms causing changes to the original structure.

  9. Composition • Combining elements to make a whole.

  10. Mineral • Minerals are naturally occurring. They are usually solid and feature a crystal structure as well as chemical composition.

  11. Observable • Capable of being seen.

  12. Luster • How a mineral appears to reflect light, and how shiny or dull the mineral is.

  13. Color • Color results from a mineral’s chemical composition and impurities.

  14. Cleavage • Fracture and parting ofatomsin a mineral, and the pattern which it breaks when put under stress.

  15. Streak • Color of the powder produced when it is dragged across a streak plate.

  16. Moh’s Hardness Scale • List of minerals numbered 1 to 10 on a scale of softness (1) or hardness (10). 1. Talc 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Orthoclase Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond

  17. Minerals make up Earth's rocks, sands, and soils.  Rocks are minerals, but minerals are not rocks.

  18. Molten • Molten rock is rock heated to a temperature that turns it into a thick liquid.

  19. Weathering and Erosion • breaking down of rocks, soil and minerals

  20. Deposit • Rocks and minerals that are moved to a different location through weathering and erosion.

  21. Compacted • Pressure on the rock with the weight of overlying layers. This squashes grains together more tightly. 

  22. Transformed • Change in composition or structure

  23. Igneous Rock • Igneous rocks are formed from molten rock called magma. They are mostly made up of interlocking crystals and are usually very hard to break. Granite Basalt Pumice

  24. Sedimentary Rock • Sedimentary rocks are formed from sediment grains deposited by water, wind or ice. They are always formed in layers, and often contain fossils. Conglomerate Sandstone Limestone and Chalk

  25. Metamorphic Rock • Metamorphic rocks were once igneous or sedimentary rocks, but have been changed as a result of intense heat and/or pressure within the Earth’s crust. Schist Shale Gneiss Marble
