why do stars twinkle
Answers
Explanation:
In fact, most of the stars are shining with a steady light. The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. ... To our eyes, this makes the star seem to twinkle.

mark my answer as brainliest plz.....
Answer:
Twinkling of stars is due to atmospheric refraction of starlight. The starlight after entering the earth's atmosphere undergoes refraction in a continuous manner before it reaches the Earth. The atmospheric refraction is due to a change in the refractive index at different levels in the atmosphere. The starlights bends towards the normal, the apparent position is different from the actual position of the star. Since the atmosphere is not stationary and keeps changing. As the path of rays of light coming from star varies slightly then the apparent position of the star also varies slightly and the amount of light entering the eye flickers. Sometimes, it is brighter and sometimes the star seems fainter. In this way, the stars twinkle.
