USGS maps are also known as what type of maps?

1. Geological and geological

2. Quadrangle and topographic

3. Elevation and contour

4. City and terrain

The correct answer is: Quadrangle and topographic

USGS maps are commonly referred to as quadrangle and topographic maps, which are produced by the United States Geological Survey. These maps are critical tools for understanding the geography of an area, displaying both natural and artificial features in a detailed manner. Quadrangle maps show a specific area of land, divided into quadrangles based on latitude and longitude, while topographic maps include contour lines that represent elevation changes, providing a three-dimensional perspective on the landscape. The inclusion of features such as rivers, roads, and terrain contours in these maps makes them invaluable for planning, resource management, and navigation. Their detailed representation of topography allows users to visualize landforms and assess potential impacts on water flow, making them essential for stormwater management and environmental studies.
