why dous tha earth look blue from space ?​

Answer 1

Answer:

Earth looks blue from outer space because about two-thirds of the planet is covered with water. In fact, Earth is called the “Blue Planet” for this reason. (In reality, the oceans aren’t blue; they only appear that way because the water reflects the color of the sky overhead—which also appears to us as blue, due to refraction of light.)

The sunlight through appears white it is actually a combination of lights of several different colors (Violet, indigo, blue, green, yellow, orange and red).
