Prime Meridian vs Axis

The Prime Meridian and Axis are both important concepts in geography and astronomy, but they serve different purposes and have distinct characteristics.

Prime Meridian:
- The Prime Meridian is an imaginary line that represents 0 degrees longitude on the Earth's surface.
- It runs from the North Pole to the South Pole, passing through Greenwich, England, which is why it is also known as the Greenwich Meridian.
- The Prime Meridian divides the Earth into the Eastern Hemisphere and the Western Hemisphere.
- It serves as a reference point for measuring longitude, with locations to the east of the Prime Meridian having positive longitudes and locations to the west having negative longitudes.

Axis:
- The Earth's axis is an imaginary line that runs through the center of the Earth from the North Pole to the South Pole.
- It is tilted at an angle of approximately 23.5 degrees relative to the plane of the Earth's orbit around the Sun.
- The Earth's axis is responsible for the changing seasons as different parts of the Earth receive varying amounts of sunlight depending on their position relative to the Sun.
- The axis also determines the length of daylight hours and the angle of the Sun in the sky at different times of the year.

In summary, the Prime Meridian is a reference line for measuring longitude on the Earth's surface, while the Earth's axis is an imaginary line that determines the tilt of the Earth and is responsible for the changing seasons. Both concepts play crucial roles in understanding Earth's geography and astronomical phenomena.
