Elevation levels above sea level .
That would be a topographical map. It uses contour lines (usually 100 or 50 ft. incraments) to show elevation above or below sea level. They're usually black & white and can be found wherever you can find maps.
As you travel farther away from sea level on a contour map, the land elevation increases. This means you are moving to higher ground or ascending in altitude. The contour lines on the map will be closer together, indicating a steeper slope or terrain as you move further from sea level.
The x inside the contour lines represents the elevation or value of the variable being mapped, such as elevation on a topographic map or temperature on a weather map. This value indicates the specific level at that particular point on the map.
The contour lines on a map indicate changes in elevation above sea level (or below, occasionally). The amount of change in elevation between lines is shown on the map legend, and will vary depending on the size of the map and the type of terrain.
Acontour line (also level set, isopleth, isoline, isogram or isarithm) of a function of two variables is a curve along which the function has a constant value.[1] In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level.[2] A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes.[3] The contour interval of a contour map is the difference in elevation between successive contour lines.[4] A contour interval is basically the same thing.

That would be a topographical map. It uses contour lines (usually 100 or 50 ft. incraments) to show elevation above or below sea level. They're usually black & white and can be found wherever you can find maps.

A contour interval is the vertical distance between two contour lines on a map, representing the change in elevation. An index contour is a thicker contour line labeled with the elevation of the line above sea level, typically every fifth contour line. It helps users quickly identify elevation values on a map.
The numerical values along the lines of contour, indicate the elevation above or below sea level.
the distance between mean sea level and any given contour line
The contour lines on a map indicate changes in elevation above sea level (or below, occasionally). The amount of change in elevation between lines is shown on the map legend, and will vary depending on the size of the map and the type of terrain.
A contour line on a topographic map represents a specific elevation above sea level. It connects points of equal elevation and helps to show the shape of the land, such as hills, valleys, and slopes. The spacing between contour lines indicates the steepness of the terrain.
