Hi there! Let's talk about the sky!
Imagine the sky like a big, blue blanket that covers our Earth. When you look up, that blanket is what you see! But where does it start and where does it end? Here’s how to understand it step by step:
- Start with the Earth: The sky is all around us. It starts right where the ground ends. So, when you look up from the ground, you can see the sky overhead.
- The Color of the Sky: During the day, the sky looks blue. This is because of something called 'scattering,' which means that sunlight spreads out in different directions. In the morning and evening, the sky can turn pretty colors like orange, pink, and purple!
- How High is the Sky? The sky goes really high up, but it doesn’t have a hard line where it ends like a wall. It just keeps getting airier and thinner. It can go up for many miles! Planes fly in the sky, and they can go up to around 10 miles high!
- Outer Space: If you keep going up, you eventually reach a point where the sky fades into outer space. This is where stars and planets are! Scientists say that this part starts around 62 miles (100 kilometers) from the Earth.
- Remember: It's important to know that the sky is always around us, even if we can’t see it at night! It’s just hiding behind the darkness.
So, to sum it up, the sky starts just above us at the ground and slowly goes up and up into the thinner air and eventually into space! Isn't that amazing?
