Which one of the following is not correctly matched ?

Question

Accepted Answer

Option 3 is correctly identified as the incorrect match because the Prime Meridian is not located at 90° Eastern Longitude. The Prime Meridian is actually located at 0° longitude. It is the meridian (line of longitude) at which the longitude is defined to be 0°. This line runs through the Royal Observatory in Greenwich, London, and is used as the starting point for measuring degrees of east and west longitude around the Earth.

Now, let's explain why each of the other options is correct:

1. **Tropic of Cancer – 23.5° N**: This is correctly matched. The Tropic of Cancer is a circle of latitude located at approximately 23.5° North of the Equator. It marks the northernmost point at which the sun can appear directly overhead at noon, which occurs during the June solstice.

2. **Tropic of Capricorn – 23.5° S**: This is also correctly matched. The Tropic of Capricorn is a circle of latitude located at approximately 23.5° South of the Equator. It marks the southernmost point at which the sun can appear directly overhead at noon, which occurs during the December solstice.

4. **International Date Line – 180° East and 180° West Longitude**: This is correctly matched. The International Date Line is an imaginary line of longitude located at approximately 180° from the Prime Meridian. It is not a straight line but zigzags to avoid dividing countries and territories. It serves as the line of demarcation where the date changes by one day when crossed.

In summary, Option 3 is the incorrect match because the Prime Meridian is at 0° longitude, not 90° Eastern Longitude. The other options are correctly matched with their respective geographical lines.
