Answer:
1- Why is the sky blue?
ans- Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white.
2- Why can I sometimes see the moon during the day?
ans- When the Moon is close to the Sun in the sky, the Sun is too bright for us to see it. As it moves away from the Sun in the sky each day, we see it emerge as a thin crescent. This called the New Moon. If you look closely, you can see the faint glow of the “dark” part of the Moon
3- Why do birds fly south in the winter?
ans- Birds will generally migrate to the south for winter simply to be warmer. They’ll generally head fairly close to the equator for this, as that’s where it’s warmest year-round.
