| Question | Answer |
| What does CI stand for? | Contour Interval |
| Where do I find the amount of elevation change for a CI? | On the legend. |
| How many contour intervals are there between major bands, typically? | 5 |
| What is the elevation difference if I cross 5 contour lines and the CI is 50 ft? | 250 ft |
| What is the formula for slope %? | rise/run * 100 |
| What is rise? | Change in elevation (vertical distance) |
| What is run | Horizontal distance between two points on the map. |
| If rise increases but run stays the same, what happens to the slope? | It increases. |
| If the rise is the same, but the run differs, which run has the greatest slope %? | The smallest run |
| If the run is the same, but the rise differs, which rise has the greatest slope %? | The greatest rise |
| What is clastic? | A rock made of of broken pieces of older rocks. |
| What is Igneous rock? | Rocks formed from cooled magma or lava. |
| Is asphalt a mineral? | No, it's man made. |
| Are gems minerals | Yes |
| What are minerals | naturally occuring representable by a chemical formula inorganic has a crystaline structure |
| What the difference between a rock and a mineral | Rocks are a mixture of minerals. Minerals have a specific chemical formula. |
| Is granite a rock or mineral | Rock it's made up of three minerals quartz feldspar biotite |
| What does aggregate mean | Mixture |
| What does crystalline mean | having a crystal structure, the atoms are arranged in a neat pattern |
| What's a silicate | a salt containing silicon most silicates also contain oxygen silicates are anionic (they have a negative charge) |
| What does anionic mean | it has a negative charge because there are more electrons than protons |
| What's an anionic compound | a mixture of two or more things and the overall mixture has a negative charge |
| what is tuff | a light porus rock made from volcanic ash |
| what is a flood basalt | the result of a gigantic volcanic eruption it coats large areas of land or ocean floor they commonly have a stair step appearance |
| what does basalt mean | it's a fine grained igneous rock it's made mainly of feldspar it is commonly half silica it commonly has a glassy appearance with mineral grains mixed in |
| what's a composite volcano | also called stratovolcano they look like the typical cone volcano shield volcanoes are different they are flatter and broader there are 452 stratovolcanoes in the pacific ring of fire think of stratosphere |
| what's a caldera | a large volcano shaped like a crater it's formed by an emptied magma chamber caldera is from "cauldron" think of a big cooking pot |
| volcanic dome | also called a lava dome a large mound formed by lava being squeezed out of the ground |
| what's a scoria cone | also known as cinder cone they are the smallest and most common type of volcano they look like a cone with a hole in the top (like a combination stratovolcano and caldera) |
| what's a lagoon | a shallow body of water separated from a larger body of water by barrier islands or reefs |
| what's a sheild volcano | a volcano that is a flattened dome the sides are not nearly a step as a composite volcano (stratovolcano) |
| what are tidal flats | also known as mud flats they are formed when tides or rivers deposit mud they are usually found in sheltered areas |
