They don't. All you have there is one great circle and one great semi-circle,
on the same spherical surface, that are perpendicular where they intersect.
If you want a grid, you'll have to find an old 6L6GB or a 12AT7 somewhere.
The Equator and Prime Meridian
longitude, latitude, equator, prime meridian
The prime meridian and the equator are alike because they are both invisible lines that split the earth in half. The equator is horizontal (side to side) and the prime meridian is vertical (up and down). The equator divides the Northern and Southern Hemisphere and the Prime Meridian divides the Western and Eastern Hemisphere.

The two imaginary base lines used to create a grid for locating points on Earth are the equator (latitude) and the prime meridian (longitude). The equator divides the Earth into the Northern and Southern Hemispheres, while the prime meridian divides it into the Eastern and Western Hemispheres. Together, these lines form a grid system that helps to pinpoint specific locations on Earth.
The Prime Meridian and the Equator are two of the most significant lines of latitude and longitude that divide the Earth into hemispheres. The Equator, which is at 0 degrees latitude, divides the Earth into the Northern and Southern Hemispheres. The Prime Meridian, located at 0 degrees longitude, separates the Eastern and Western Hemispheres. Together, they create a grid system that helps in navigation and geographic orientation.
The two imaginary lines around the world are the Equator and the Prime Meridian. The Equator is located at 0 degrees latitude and divides the Earth into the Northern and Southern Hemispheres, while the Prime Meridian, located at 0 degrees longitude, separates the Eastern and Western Hemispheres. Together, they form a grid system that helps in navigation and geographical orientation.
The equator divides the Earth into two. Each half is called a hemisphere. The equator divides Earth into northern and southern hemispheres. The prime meridian and the 180 dgrees meridian divide Earth into eastern and western hemispheres.
The latitude and longitude lines can cover the globe to form a grid, called a graticule. The point of origin of the graticule is (0,0), where the equator and the prime meridian intersect. Source: http://publib.boulder.ibm.com/
Geographers use the prime meridian as the starting point for measuring longitude around the globe. It helps establish a reference point for determining locations in terms of east-west distance. By using the prime meridian in conjunction with the Equator, geographers can create a grid system to pinpoint any location on Earth.
