My science teacher gave me these questions can you answer them. Why is the sky blue?
1. Why does the moon appear in the daytime?
2. How much does the sky weigh?
3. How much does the Earth weigh?
4. How do airplanes stay in the air?
5. Why is water wet?
6. What makes a rainbow?
7. Why don't birds get electrocuted when they land on an electric wire?
8. Do aliens exist?
9. Where do birds go in the winter?
10. Why is the ocean blue?
11. Why is the sun the only star that can be seen during the daytime?
12. Blue sky over a green hillside.

The sky is blue because the air scatters blue light from the Sun across the sky and down to our eyes.

1:( sorry l don't know) :-(

2: 14.7 lbs per square inch

3: 5.972 × 10^24 kg

4: (sorry l don't know):'(

5: Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.”

6: A rainbow is caused by sunlight and atmospheric conditions.

7: Because the electricity is always looking for a way to get to the ground.

8: No

9.:the Birds fly from north to south each winter, and then they head back north when the temperatures warm up.

10: The ocean is blue because water absorbs colors in the red part of the light spectrum.

11: In the daytime we see the sun shine. Our sun is a very bright star. The sun's bright light blocks out other stars. It blocks out stars that are not as bright.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
