Factors to change earths rotation or revolution!!

In December 2004 a tsunami hit coastal areas around the Indian Ocean. This tsunami caused not only severe damage and loss of lives, but also affected the earths rotation. the tsunami shifted coastlines and elevations thus interfering with Earths rotation.

Now I am going to grace you with the knowledge about how scientists came to the conclusion of Neptune has seasons. The discovery of Neptune having spring occurred early on this year. Astronomer Larry Sromovsky states that he became aware of Neptune having a season by physical changes around its atmosphere. Such as bands of clouds becoming larger. Scientist have come to one theory about the seasonal changes, and that is, the brightness from the sun as Neptune revolves around it changes to various seasons.
