A contour line that is bold and labeled is called an index contour line. These lines help to easily identify specific elevations on a topographic map.
The horizontal lines on a map or globe that indicate distance north or south of the Equator.
Each contour line represents a rise in height (elevation). The closer the contour lines are on the map, the steeper is the slope.
A contour line on a topographic map is typically labeled with the elevation in round units. This helps to indicate the elevation of the land and the change in elevation across the map.
Contour lines on a topographic map that are close together indicate a steep slope, while contour lines that are far apart indicate a gentle slope. If the contour lines form a V-shape pointing uphill, it indicates a valley, and if they form a V-shape pointing downhill, it indicates a ridge. The contour lines help users visualize the shape and steepness of the land surface.
It depends on the scale of the map, the range of values attained within the area of the map, the units of measurement and the accuracy of the contour data.
A contour map is a physical map showing elevation and each line shows a major change in elevation.
A contour line that is bold and labeled is called an index contour line. These lines help to easily identify specific elevations on a topographic map.

Depending on the type of map you are referring to, the solid black line could indicate a national boundary. If it is a map of states, it could be a state boundary.
a countour map shows elevation, while YOU should find out what a special purpose map is. It's not that hard. try google.
Contour lines on a map are typically brown or black in color. They indicate elevation changes on the map.
A wavy blue line on a map usually indicates water. I could indicate a river, canal, or any type of waterway.
Closely spaced contour line on a topographic map shows that the land is steep.
It might indicate a water route. Can you be more specific?
The horizontal lines on a map or globe that indicate distance north or south of the Equator.
A line on a map joining points of equal height above or below sea level.
