To model a hypothetical situation where every location on Earth experiences 12 hours of daylight and 12 hours of darkness every day, you would use a diagram that represents a hypothetical scenario where the Earth's axial tilt is zero, and it is positioned in such a way that sunlight evenly illuminates both hemispheres.
One common type of diagram to visualize this would be a:
-
Schematic Earth diagram: This diagram would show a cylindrical representation where the sun is casting light evenly across the entire Earth. The Earth's equator would be equally illuminated by sunlight at all times, allowing for uniform distribution of light.
-
Equatorial Light Bulb Model: You could also think of a globe with a light source (the sun) at the center, with rays extending outward in all directions, reaching every part of the globe equally, indicating that neither side experiences longer days or nights.
-
Daily Cycle Diagram: A circle divided into 24 equal segments could also represent hours of day and night, showing that every point on the globe experiences 12 segments of light (daylight) and 12 segments of dark (nighttime).
These types of diagrams will effectively indicate the concept of equal daylight and nighttime across the globe, as in this hypothetical scenario.
