The sun hits bodies of water (ponds, oceans, pools, puddles) and it evaporates into a gas known as water vapor which goes up and forms a cloud. When the cloud gets heavy the water condensates back into little droplets and falls back to the ground. This is rain.
Wet land reduce the evaporation rate thus improve water quality.
Answer:
Air molecules scatter blue light more efficiently than other colors.
Explanation:
The sunlight has many colors and each of them has a different wavelenght. The color blue has shorter wavelengths and higher frequencies than the other colors. So, as sunlight goes through the air, the blue part causes charged particles to oscillate faster than the red part does and it is scattered more efficiently than the other colors and that's the reason for the sky to be blue.
