Question

topographic
a topographic map is similar to a physical map in that it shows different physical landscape features. unlike physical maps, though, this type of map uses contour lines instead of colors to show changes in the landscape. contour lines on topographic maps are normally spaced at regular intervals to show elevation changes. when lines are close together, it means the terrain is steep.
climate
a climate map shows information about the climate of an area. these maps can show things like the specific climatic zones of an area based on the temperature, the amount of snow an area receives, or the average number of cloudy days. these maps normally use colors to show different climatic areas.
