nullWe will learn about day and night when we see the sun shining in the sky. IT is day and when we don't at night. So the question is, why is the sun in the sky seen? And sometimes, and not at others, we see that the sun seems to move across the sky, starting in the east in the morning, then move toward the south, noon, and then finally toward the west as the day ends. Hm, how does this happen? Actually, the sun appears to move across the sky because the earth rotates on its axis. Access is imaginary straight line passing through the north pole, the center of the earth and the south pole. IT is tilted at an angle of twenty three point five degrees. The movement of the earth on its own axis is known as rotation. Let's see why we have days and nights. Let us soon. This global is our earth. And this lamp is the sun. Now looked closely, the light is shining only on one side. This is day. Now look at the other part, and you can see it's dark. This is night. When the earth rotate, day changes to the night, and night changes today. That's how the rotation of the earth causes day and night. Pretty cool. Look at this map. India and the united states are on opposite side. The earth takes a whole day to make one rotation, which is a total of twenty four hours. That's why when there is day in india, there is night in the united states. And when there is day in the united states, there is night in india. Similarly, when there is day in china, there is night in columbia, because these are situated on the opposite sides of the earth. Let's learn some fun facts about day and night. The earth is always spinning around, and IT takes twenty four hours for the earth to complete one rotation. Daytime is from the time of sun rise until sun set. Nights is from the time the sun sets and fill the sun rises. The shortest st day of the year is known as the winter solstice. The longest day of the year is known as the summer souls. This, the sun contains ninety nine percent of the solar system mass. Now you know a lot about day and night applied. Stay tuned for more.
