The Prime Meridian is at 0 degrees, and the opposite side is at 180 degrees. Since there are 360 degrees in a full circle, 180 degrees is on the opposite side, and 90 degrees West is halfway between the Prime Meridian and 180 degrees.

Which line of longitude is directly opposite the Prime Meridian?a)90 d...
Understanding the Prime Meridian
The Prime Meridian is defined as 0 degrees longitude and serves as the reference point for measuring longitude across the globe. It runs from the North Pole to the South Pole, passing through Greenwich, England.
What is Opposite Longitude?
The line of longitude directly opposite the Prime Meridian can be determined by adding or subtracting 180 degrees.
Calculating the Opposite
- Starting from the Prime Meridian at 0 degrees:
- Adding 180 degrees:
0 degrees + 180 degrees = 180 degrees
- Subtracting 180 degrees:
0 degrees - 180 degrees = -180 degrees (which is equivalent to 180 degrees)
Thus, the line of longitude directly opposite the Prime Meridian is 180 degrees.
Options Analysis
Let’s evaluate the given options:
- a) 90 degrees East: This is 90 degrees to the east of the Prime Meridian.
- b) 180 degrees: This is the correct answer as it lies directly opposite the Prime Meridian.
- c) 90 degrees West: This is 90 degrees to the west of the Prime Meridian.
- d) 360 degrees: This is equivalent to 0 degrees, returning to the Prime Meridian.
Conclusion
The correct answer is b) 180 degrees. This line of longitude is also significant as it roughly corresponds to the International Date Line, which is where the calendar day changes.
