- 1What does CI stand for?Contour Interval
- 2Where do I find the amount of elevation change for a CI?On the legend.
- 3How many contour intervals are there between major bands, typically?5
- 4What is the elevation difference if I cross 5 contour lines and the CI is 50 ft?250 ft
- 5What is the formula for slope %?rise/run * 100
- 6What is rise?Change in elevation (vertical distance)
- 7What is runHorizontal distance between two points on the map.
- 8If rise increases but run stays the same, what happens to the slope?It increases.
- 9If the rise is the same, but the run differs, which run has the greatest slope %?The smallest run
- 10If the run is the same, but the rise differs, which rise has the greatest slope %?The greatest rise
- 11What is clastic?A rock made of of broken pieces of older rocks.
- 12What is Igneous rock?Rocks formed from cooled magma or lava.
- 13Is asphalt a mineral?No, it's man made.
- 14Are gems mineralsYes
- 15What are mineralsnaturally occuring
representable by a chemical formula
inorganic
has a crystaline structure - 16What the difference between a rock and a mineralRocks are a mixture of minerals. Minerals have a specific chemical formula.
- 17Is granite a rock or mineralRock it's made up of three minerals
quartz
feldspar
biotite - 18What does aggregate meanMixture
- 19What does crystalline meanhaving a crystal structure, the atoms are arranged in a neat pattern
- 20What's a silicatea salt containing silicon
most silicates also contain oxygen
silicates are anionic (they have a negative charge) - 21What does anionic meanit has a negative charge because there are more electrons than protons
- 22What's an anionic compounda mixture of two or more things and the overall mixture has a negative charge
- 23what is tuffa light porus rock made from volcanic ash
- 24what is a flood basaltthe result of a gigantic volcanic eruption
it coats large areas of land or ocean floor
they commonly have a stair step appearance - 25what does basalt meanit'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 - 26what's a composite volcanoalso 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 - 27what's a calderaa large volcano shaped like a crater
it's formed by an emptied magma chamber
caldera is from "cauldron"
think of a big cooking pot - 28volcanic domealso called a lava dome
a large mound formed by lava being squeezed out of the ground - 29what's a scoria conealso 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) - 30what's a lagoona shallow body of water separated from a larger body of water by barrier islands or reefs
- 31what's a sheild volcanoa volcano that is a flattened dome
the sides are not nearly a step as a composite volcano (stratovolcano) - 32what are tidal flatsalso known as mud flats
they are formed when tides or rivers deposit mud
they are usually found in sheltered areas - 33—
