Answer:
1.The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. ... These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue.
2. 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. ... "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."
3. This means the sky weighs 14.7 lbs per square inch of earth surface which is roughly 11 billion billion pounds. So, you can say that sky weighs one millionth of the mass of the Earth.
4.5.972 × 10^24 kg
6.Water is wet because when you have water on your clothes or skin it evaporates into the surrounding air. Evaporation produces cooling because it's like energy.
7.A rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.
