Answer:
ans1-Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. ... More of the sunlight entering the atmosphere is blue than violet, however, and our eyes are somewhat more sensitive to blue light than to violet light, so the sky appears blue.

The surface of the moon is reflecting the sun's light into our eyes. ... "When we see the moon during the day it's because the moon is in the right spot in the sky and it's reflecting enough light to be as bright, or brighter, than the sky."

So, you can say that sky weighs one millionth of the mass of the Earth.

1.and 2.) Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. ... More of the sunlight entering the atmosphere is blue than violet, however, and our eyes are somewhat more sensitive to blue light than to violet light, so the sky appears blue.
3. We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes. ... But we don't see the moon all the time during the day, and that's because of where the moon might be in the sky.
4.) about 5 million billion tons
All that air, the entire atmosphere, weighs about 5 million billion tons! We don't get crushed because all that weight is distributed evenly over the entire surface of the Earth. The average force you feel is about 15 pounds on every square inch of your body.
5.) 5.972 × 10^24 kg
6.)Four forces keep an airplane in the sky. They are lift, weight, thrust and drag. Lift pushes the airplane up. The way air moves around the wings gives the airplane lift.
7.)“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.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each.
8.)Sunlight is white light and is made up of all the wavelengths of the visible spectrum. The colors we see in the rainbow are a result of sunlight hitting individual water drops where reflection and refraction of the light gives us a rainbow. When sunlight hits a water drop some of the light enters the drop.
9.)Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.
