longitude I think it is the prime Meridan well at least I think
Lines on a globe that resemble a checkerboard pattern are likely to be latitude and longitude lines. Latitude lines run horizontally around the globe, measuring the distance north or south of the equator, while longitude lines run vertically, measuring the distance east or west of the prime meridian. These lines help pinpoint specific locations on Earth's surface.
latitude longitude
The imaginary lines that run north and south around the globe are called "meridians." They are used to measure longitude and converge at the poles. The prime meridian, which is located at 0 degrees longitude, serves as the starting point for measuring these lines.
A meridian is a line of longitude running north-south on the Earth's surface, while a parallel is a line of latitude running east-west. Meridians converge at the poles, while parallels are equidistant from each other. Meridians help in determining time zones, while parallels help in measuring distance from the equator.
Lines of Latitude
Some maps and globes have 'lines' printed on them, and some don't. If there are lines on the globe, they're a convenience to help you estimate the location of a place you might want to find again later, by giving you a scale of numbers to measure the spot against. They're 'scales' for measuring, just like the marks on a ruler. But instead of making you use a ruler and try to wrap it around the globe, they print the rulers right on the globe for you.
latitude
The globe grid is formed by lines of latitude and longitude. Lines of latitude run horizontally, measuring distance north or south of the equator, while lines of longitude run vertically, measuring distance east or west of the Prime Meridian. Together, these lines create a coordinate system that helps in locating any point on the Earth's surface. The intersection of these lines provides a precise geographic reference for navigation and mapping.
Equator latitude lines
The term "meridian" is used to describe lines running from the North Pole to the South Pole, like longitudes, and circle the Earth vertically.
The lines of latitude are lines that go east and west around the globe or map ,the equater us the line in the middle that separates north and south :)
The lines of longitude and the lines of latitude are on the globe if you look! Our expedition will follow a line of longitude.
