Multiple choice general knowledge

Why doesn't Earth's orbit cause seasonal temperature changes on Earth?

  1. The change in distance is actually minimal. Earth's tilted axis is the real cause of seasons on Earth.

  2. Even though Earth's orbit is an ellipse, the change in distance from the Sun is only an optical illusion.

  3. The change in distance is the real cause of seasons on Earth.

  4. The change in distance occurs at the same time as the seasons, so we don't notice the change.

A Correct answer
Explanation

Earth's orbit is nearly circular with only about 3% variation in distance throughout the year - from 147 million km at perihelion to 152 million km at aphelion. This small change cannot explain seasonal temperature differences. Instead, Earth's 23.5-degree axial tilt means different parts of Earth receive varying solar intensity at different times of year. Option B is wrong - the orbital shape change is real, not an illusion. Option C is factually incorrect. Option D is illogical - timing correlation doesn't explain causation.
