There are several types of maps that illustrate different information. Political maps show state and national boundaries as well as capital and major cities. Physical maps depict physical features like mountains, rivers, and lakes using colors to represent elevation. Resource maps indicate the natural resources or economic activities that dominate an area using symbols. Climate maps provide general climate and precipitation information using colors to represent zones. Topographic maps use contour lines to show land elevation and slope with closer lines indicating steeper slopes. Thematic maps focus on a specific subject like population, languages, or income through the use of data.
