Give Reason:-
why sky is blue?why did it gives reflection?
Difference Between:-
Revolution and Rotation
Answers
Answer:
Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. ... Also, the surface of Earth has reflected and scattered the light.
Rotation of the Earth is its turning on its axis. Revolution is the movement of the Earth around the Sun. The Earth takes 24 hours to complete a rotation with respect to the sun. ... The path of the Earth moving around the Sun is called an orbit.

Answer:
1)When we look at an arbitrary point in the sky, away from the sun, we see only the light that was redirected by the atmosphere into our line of sight. Because that occurs much more often for blue light than for red, the sky appears blue.

2)Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth's rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun. This movement is called revolution.
This is your answer.
