Choosing the topic that I will explain was an important station for me, since I tend to astronomy and as I am fond of studying planets and love to dive in space and learn about its mysteries, I decided to be myself and to choose a topic related to the movement of the earth and the sun in order to present the best presentation about it because It highlights my personality and my passion for this field. I tried to choose a topic that I would enjoy while researching, and I mainly wanted to correct a common misconception among people. I made the final decision, "that is, I will discuss the issue of the reason for the succession of seasons" immediately after I asked my friends about the reason and they replied that it is the distance between the earth and the sun, here I noticed that many believe this, so I decided to contribute via video to explain this topic
