Study Notes
Properties of the Global Grid
- All meridians are of equal length, ensuring uniformity across the globe.
- Meridians converge at the poles, serving as "true" north-south lines, distinct from magnetic north-south lines.
- Lines of latitude run parallel to the equator, maintaining consistent spacing between each other.
- The lengths of parallels decrease as they get closer to the poles, illustrating the globe's curvature.
- Meridians and parallels intersect at right angles (90 degrees), creating a grid-like structure on the Earth's surface.
- The scale of measurement on the Earth's surface remains constant in every direction, providing uniformity in distance and area calculations.
