Contour lines connect points of equal height, and show grades of hills, the closer together the lines the steeper the grade. The map legend should tell you the difference in elevation between lines, this could be in feet or meters
Contour lines are used in maps to represent elevation changes on the earth's surface. By showing lines of equal elevation, contour lines help visualize the shape of the terrain and identify features such as hills, valleys, and slopes. They are essential for hikers, planners, and scientists to navigate and understand the topography of an area.

cartography or for the person that makes the maps that would be a cartographer
On topographic maps, contour lines that are far apart indicate gentle slopes or gradual changes in elevation. The farther apart the contour lines, the flatter the terrain.
The dotted lines in the oceans on Google Maps typically represent various maritime boundaries, such as exclusive economic zones (EEZs), shipping routes, or underwater features like ridges and trenches. These lines help users understand navigational limits, resource rights, and the geography of the ocean floor. Additionally, they can indicate areas of interest for marine traffic or environmental monitoring.
Thick black lines on maps typically represent major roads, highways, or railways. They are used to denote routes that are important for transportation and travel.
Usually rivers or canals.
You can load KML (with points, lines, polygons, etc.) either directly on Google Maps website or via the Google Maps API. Google Maps supports KML via the Google Maps API. See related links below for details. The classic Google Maps interface supports KML via the search query. Just enter a URL to a KML file in search box and Google Maps will load the KML and render on the map, but this only works in the classic Google Maps interface.
On maps, the letter "O" is commonly used to represent oceans. This abbreviation is often found in legends or keys accompanying nautical charts or geographical maps to indicate oceanic regions. Additionally, some maps may use blue coloring or shading to visually represent ocean areas.
On maps, black lines between states represent boundaries or borders, where one state stops and the others starts. These are also called state lines.
Contour lines represent elevation changes. The closer contour lines are together, the steeper the slope. Blue lines represent water features such as rivers and lakes.
It is 147 miles according to Google Maps.
Maps was formerly known as Earth Builder. It was thought by the team that the name did not properly represent the capabilities of the product, so they replaced "earth builder" with "maps" in 2012.
To add labels to Google Maps, you can use the "My Maps" feature. First, go to Google My Maps and create a new map. You can then add markers, shapes, or lines and label them by clicking on the marker and entering the desired text in the pop-up box. Once you're finished, you can save and share your map with others.
