FAQs on Earth and sky
1. What is the sky?
Everything we see when we look up is the sky. It might be blue in the daytime and bright at night.
2. Why does it get dark at night?
The Earth revolves, so when our side of the Earth faces away from the Sun at night, it becomes dark.
3. Why moon is half sometimes?
The Moon looks half sometimes because it moves around the Earth, and the sunlight only shines on part of it. When the lit part faces us, we see a half Moon.
4. Why moon has different shapes?
The Moon has different shapes because of the way it moves around the Earth. Sometimes, it's a round full Moon, and other times, it's a crescent or a half Moon. This happens because the Sun's light hits it from different angles.
5. What causes day and night?
The reason day and night exist is because the Earth spins like a spinning top. It is daytime while it is facing the Sun, and dark when it is not.
