Rocks and Minerals
Facts and stuff about rocks and minerals
| Question | Answer |
|---|---|
| What are some ways of classifing a Mineral? | The color of a Mineral's streak, the color of the Mineral, the hardness of a Mineral, its luster, and its Unique property. |
| What is the most trustworthy way to identify a mineral? | The color of its streak. |
| What tool helps you identify the hardness of a mineral? What is the name of that tool? | A hardness scale, called the Mohs Hardness Scale. |
| Who invented the Mohs Hardness Scale? | A German scientist, named Friedrick Mohs, invented the scale. He realized that minerals could be classified by their hardness. |
| How is the Mohs scale ranked? | The scale is ranked one to ten, talc as one, diamond as ten. The numbers that are low on the scale are more easier to scratch, while the ones higher on the scale are harder to scratch. |
| How do you define hardness? | A mineral's ability to resist being scratched. |
| How would you define a mineral? | A naturally occuring, nonliving solid that has a specific chemical makeup and crystalline, or repeating structure. |
| What are some types of minerals? | Some types are quartz, diamond, and salt; copper, silver, and iron. |
| Why do scientists need mineral properties? | Scientists use mineral properties to identify 2,000 different types of minerals. |
| Can you use different minerals to help you find the hardness of an unknown mineral? | Yes. You can use minerals that you know the hardness of to test unknown minerals. You could also use common items to help you as well. |
| What are some Unique properties of minerals? | Some minerals can-glow under ultraviolent light, produce a double image, be magnetic, or can be a conductor of electricity. |
| What is the definition of mineral streak? | Color of powder left behind when the mineral is rubbed against a rough white tile or streak plate. |
| How would you define luster? | The way a mineral reflects the light. |
| What are some types of mineral lusters? | Metallic luster, waxy luster, glassy luster, pearly luster, and dull luster. |
| Why can color not be trusted to identify minerls? | There are vaireties of color, and not all types of minerals come in one type of color, like quartz. |
| What is a Unique Property of Fluorescence? | It glows under ultraviolent light. |
| What are some Unique properties of minerals? | Some minerals can-glow under ultraviolent light, produce a double image, be magnetic, or can be a conductor of electricity. |
| What is a Unique Property some types of minerals have? | If the mineral has a chemical reaction to an acid and fizzes or bubbles. Calcite will do this. |
| What is the definition of mineral streak? | Color of powder left behind when the mineral is rubbed against a rough white tile or streak plate. |
| What is a Unique Property of Calcite? | It will refract light to produce a double image. |
| How would you define luster? | The way a mineral reflects the light. |
| What is a Unique Property of Magnetism, or Lodestone? | It is magnetic. |
| What are some types of mineral lusters? | Metallic luster, waxy luster, glassy luster, pearly luster, and dull luster. |
| What is a Unique Property of Quartz? | It can conduct electicity under just the right condition, or has a electric potential. |
| Why can color not be trusted to identify minerls? | There are vaireties of color, and not all types of minerals come in one type of color, like quartz. |
| What are 2 things that are breaking apart our rocks? | Weathering and Erosion. |
| What is a Unique Property of Fluorescence? | It glows under ultraviolent light. |
| How many types of rocks are there, and what are the names of the types? | There are three types, and they are called igneous, metamorphic, and sedimentary rocks. |
| What is a Unique Property some types of minerals have? | If the mineral has a chemical reaction to an acid and fizzes or bubbles. Calcite will do this. |
| How is a rock an igneous rock? | If it was formed from lava, it is a igneous rock. |
| What is a Unique Property of Calcite? | It will refract light to produce a double image. |
| What is a Unique Property of Magnetism, or Lodestone? | It is magnetic. |
| What is a Unique Property of Quartz? | It can conduct electicity under just the right condition, or has a electric potential. |
| What are two things that are breaking down and taking away rocks? | Weathering and Erosion. |
| How many types of rocks are there, and what are the names of the types? | There are three types, and they are called igneous, metamorphic, and sedimentary rocks. |
| How is a rock an igneous rock? | If it was formed from lava, it is a igneous rock. |
| How is a rock a sedimentary rock? | If it was formed by sediment layers, was compressed, and a rock was formed, it's a sedimentary rock. |
| How is a rock a metamorphic rock? | If it was transformed from heat,water,wind... and a rock is formed, it is a metamorphic rock. |
| Do rocks stay in just one shape? | No. Rocks change from one shape to another. |
| How would you define a rock? | A natural solid that has 1 or more minerals and is classified into one of three groups. |
| What are some igneous rocks? | Basalt, Obsidian, Gabbro, Pumice, and Granite, and Rhyolite. |
| What is Basalt? | The most common igneous rock, which forms above ground. |
| What is Obsidian? | Obsidian forms above ground when lava meets water. It looks like black glass and has a black glassy luster. |
| What is Gabbro? | Grabbro forms below ground and has the same minerals as Basalt. |
| What is Pumice? | Pumice forms above ground and floats when put on water because of its air pockets and it is very light weight. |
| What is Granite? | Granite forms below ground and has very large crystals. It is not easily broken. |
| What is Rhyolite? | It forms above ground and has small crystals. |
| What is pysical weathering? | Water, Plants, and Wind. |
| What is chemical weathering? | Gases and Minerals. |
| What is Erosion? | Water and Wind. |
| What are some Sedimentary rocks? | Conglomerate, sandstone, shale, and limestone. |
| What is Conglomerate? | A sedimentary rock that is formed from sand, rounded pebbles, and larger pieces of rock. |
| What is Sandstone? | A sedimentary rock made of sediment pieces the size of sand grains. |
| What is Shale? | A sedimentary rock made of tiny, dust sized pieces of sediment. |
| What is Limestone? | A sedimentary rock that is usually formed in oceans from seashells, which are made of the mineral calcite. There is often more calcite between shells, cementing them together. |
| What are some Metamorphic rocks? | Schist, Gneiss, Slate, Quartzite, and Marble. |
| What is Schist? | A metamorphic rock that may be formed from sandstone. |
| What is Gneiss? | A metamorphic rock that can be formed when granite is put under a lot of pressure. |
| What is Slate? | A metamorphic rock that is formed from Shale. |
| What is Quartzite? | A metamorphic rock that's formed from sandstone and is made almost entirely of quartz. |
| What is Marble? | A metamorphic rock that's formed from limestone, which makes it kind of white. Other minerals give it its other colors. |
| What are some garden walls made of? | Limestone. |
| What is the Taj Mahal made of? | Marble. |
| What are some buildings, monuments, and kitchen countertops? | Granite. |
| What is the code for weathering? | Breaking. |
| What is the code for erosion? | Take away. |
| What defines a model? | Having something that stands for the real thing. |
