| Question | Answer |
|---|---|
| Relief Map | Relief maps demonstrate the contour of the subject area either with contour lines or shaded areas to indicate elevation. |
| Climate Map | Climate maps use contour lines or shading to demonstrate long-term weather conditions |
| Political Map | Political maps use lines and/or colors to demonstrate the boundaries of political entities. Some political maps use color and size of type to demonstrate political boundaries, populations and affiliations. |
| Topographical Map | Topographical maps use lines and colors to demonstrate elevation and shapes of landforms to illustrate three-dimensional shapes in two-dimensions. Lines that are close together illustrate steep inclines while lines that are far apart illustrate relatively |
| Physical Map | Physical maps use colors, lines, symbols, tints, and shading to demonstrate physical characteristics of the subject area. Physical maps often include roads and other artificial objects |
| Cylindrical Projections | In all cylindrical projections the meridians of longitude, which on the globe converge at the poles, are parallel to one another; the equator is tangent to the globe. |
| Mercator | created the first projection map in the l6th Century. Mercator projected the parallels of latitude a growing further apart as they left the equator |
| Conic Projections | superimposing a cone on the globe, projecting the surface features on a flat map with the parallels as arcs of circles with the pole—the original point of the cone—at the center. Meridians appear as straight lines that converge at the same point |
| Mollweide | Equal-Area Projections: The most useful projection maps today employ equal-area projections that use horizontal parallels.The projection is usually split mid-ocean to maintain the continuity of the landmasses. |
| Robinson | used by the United States Geographic Service |
| Climate | temperature, precipitation, and wind. |
| Latitude | a measure of distance north or south of the equator that is expressed in degrees. |
| Tundra | vast treeless plains of the arctic region. Extremely cold temperatures and permafrost (permanently frozen subsoil) characterize the climate. |
| Tundra | shrubby plants with shallow root systems |
| Taiga | occurs in the mountains of the Northertrees of which are adapted to reduce water loss by having narrow, tough leavesn Hemisphere |
| Deciduous forest | deciduous trees (ones that lose their leaves seasonally) |
| Tropical forests | The forests occur along the equator. There are only two seasons—wet and dry |
| Deserts | descending masses of warm, dry air that create the dry climate. |
| Grasslands | climatic zones in between forest and desert where fire and grazing animals prevent the spread of trees |
| Savannahs | tropical grasslands that have patches of thorny trees. Savannas receive most of their rainfall during the wet season |
