The latitude and longitude references are lines, not points. The reference for latitude is the line that forms a circle and consists of all points with zero latitude. That line is called the "equator". The reference for longitude is the line that forms a semi-circle and consists of all points with zero longitude. That line is called the "Prime Meridian".
No. There's a point on the Prime Meridian at every possible latitude in existence.The only thing constant about the Prime Meridian, and its definition, is that everypoint on it has zero longitude.
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
The maximum longitude is 180°, at any point on the line directly opposite the Prime Meridian. (The line which, combined with the Prime Meridian, forms a complete circle around the Earth and through the poles.)
The prime meridian is located at 0 degrees longitude.
The Prime Meridian is defined as the zero reference of longitude.

No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.

The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
121 degrees east longitude
The maximum longitude is 180°, at any point on the line directly opposite the Prime Meridian. (The line which, combined with the Prime Meridian, forms a complete circle around the Earth and through the poles.)
The prime meridian is located at 0 degrees longitude.
Whether travelling to the West or to the East from the Prime Meridian (zero Longitude) the International Date Line is 180 degrees Longitude.
90 degrees 40 degrees and 90 degrees
By international agreement, the line that defines the origin of longitude is the Prime Meridian. It joins the north and south poles and passes through the Royal Observatory at Greenwich, England.
