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 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.
Latitude is a series of imaginary lines running horizontally across a map to denote position north to south. Longitude is the lines running vertically to denote east west position. Prime meridian is the line running north south, passing through Greenwich, England and is 0 degrees longitude. Equator is the same but for latitude. A grid is a series of horizontal and vertical lines arranged so you can plot position on them easily and accurately.
The two imaginary baselines used to create a grid for locating points on Earth are the Equator and the Prime Meridian. The Equator is a line of latitude that divides the Earth into Northern and Southern Hemispheres, while the Prime Meridian is a line of longitude that divides the Earth into Eastern and Western Hemispheres. Together, these two lines help establish a system of coordinates for pinpointing locations on the Earth's surface.
