Those are longitude and latitude lines.

The grid of straight and curved lines on a map is known as the coordinate grid or map grid. It is a system of horizontal and vertical lines that intersect and create a network of squares or rectangles on a map. It helps to define the location and scale of features on the map.
To understand the grid on a map, you need to know about latitude and longitude. Latitude lines, also called parallels, run horizontally across the map. They measure the distance north or south of the Equator, which is designated as 0 degrees latitude. Latitude lines are typically represented by horizontal lines on a map.
Longitude lines, also known as meridians, run vertically from pole to pole. They measure the distance east or west of the Prime Meridian, which is designated as 0 degrees longitude. Longitude lines are typically represented by vertical lines on a map.
The point where a latitude line and a longitude line intersect is called a coordinate or a grid reference. Together, these lines form a system of coordinates that provide a precise location for any point on the map.
The grid on a map allows you to locate and measure distances between different points. By identifying the latitude and longitude lines that surround a location, you can determine its specific coordinates. These coordinates are valuable for navigation, determining distances, and understanding spatial relationships on a map.
By using the latitude and longitude scale marked on the map's edges or in the map's legend, you can find the coordinates of various landmarks or destinations. These coordinates can be entered into a GPS device, mobile app, or online map to get accurate directions and distances.
In summary, the grid of straight and curved lines on a map is the coordinate grid, which consists of latitude and longitude lines. It helps identify specific locations and measure distances accurately.
