This longitude cuts right through the heart of Alaska and through French Polynesia. It also cuts through a part of Antarctica.
The imaginary line that divides the Earth into east and west longitude is called the Prime Meridian. It is located at 0 degrees longitude and passes through Greenwich, London, UK.
The line of longitude for a place that is halfway between the prime meridian and the 80th line of longitude and west of the prime meridian would be -40 degrees longitude. The prime meridian is at 0 degrees, and halfway between 0 and 80 is 40 degrees. Since the location is west of the prime meridian, the longitude would be measured as negative.
