| Question | Answer |
|---|---|
| What are the steps to the scientific method? | Observation, hypothesis, experiment/measurement, results, theory development |
| What is a map? | universal language, tool for spatial analysis, a model of an area ( in reduced size) |
| what do dot maps represent? | the density of people in areas |
| Isobar maps | lines of equal pressure |
| Isohyet maps | lines of equal rainfall |
| Isotherm map | lines of equal temperature |
| hypsometric maps | measurement of land elevation relative to sea level |
| Bathymetric Maps | measurement of sea depth relative to sea level |
| map scale | relation between reality and the map |
| Equidistant | length is preserved, usually on large scale maps |
| Large scale | small area |
| small scale | large area |
| equal area | area preserving, shape of the earth changes cannot be angle preserving |
| equal angle | scale is the same in any direction at a given point |
| What is a thematic map? | shows the spatial distribution of some type of data over a geographic area |
| What is a Planimetric map? | shows the horizontal position of boundaries, bodies of water, economic and cultural features |
| what is a topographic map? | portrays physical relief through the use of contour lines that connect all points at the same elevation |
| true or false, elevation lines that are closer together equate to steeper elevation? | true |
| equally spaced elevation lines | uniform graph |
| steeper at the top and less elevated at the bottom would produce what graph | concave graph |
| less steep at the top and more steep at the bottom would produce what graph... | convex |
| When would you use hatched contour lines? | when drawing a depression |
| When drawing a river what does the base of the V represent? | The base of the V points upstream (against the current) |
| What landform is an obvious violation of topographic maps? | overhangs in canyons or cliffs because the elevation is too steep to show with contour lines |
| what are geodedic control points | used to define absolute positioning (locations) on a map |
