Coordinate Grids, I believe.
This is called a map projection.
Coplanar lines that do not intersect are called parallel lines.
"Parallels" of latitude. Those are the lines that are drawn horizontal on the globe or map.
The line that indicates an elevation on a map is called a contour line. Contour lines connect points of equal elevation, helping to visualize the terrain's shape and steepness. The spacing between these lines indicates the slope; closely spaced lines signify steep terrain, while widely spaced lines indicate a gentler slope.
This is a "grid."
The horizontal lines are called latitudes and the vertical lines are called longitudes.
The are called Contour Lines.
Lines on a map connecting places with equal humidity are called isohyets.
A map with contour lines is called a topographic map. These lines represent changes in elevation and help to visualize the shape of the terrain. Topographic maps are commonly used for hiking, surveying, and land navigation.
The lines are parallel on the map are called Latitudes.
They are called the magnetic field lines.
They are called the magnetic field lines.
They are called the magnetic field lines.
Called both Elevation Lines or Contour Lines
The lines that are perpendicular to the latitude lines on a map are called longitudinal lines. There are 24 of them, each representing 15 degrees of change.
The lines on a topographic map are called contour lines. These lines represent points of equal elevation above or below a reference point, such as sea level. Contour lines help us visualize the shape and features of the land surface on a two-dimensional map.
