The physiological phenomenon of the twinkling of stars observed from Earth is primarily on account of:
- Alarge distance of stars and storms in air.
- Brotation of earth
- Clarge size of stars
- Dlarge distance of stars and fluctuations in the density of air.
Solution & Step-by-step Explanation
Stars act as point sources of light due to their immense distances from Earth. As starlight passes down through different shifting layers of the Earth's atmosphere, it undergoes continuous atmospheric refraction due to temperature gradients and localized fluctuations in air density. This causes the apparent position and intense brightness of the star to fluctuate rapidly.
