Question

1. Why does the earth appear blue from space?​

Answer 1

Answer:

The earth is largely (71 percent of the surface of the earth) covered by water. Water blocks the radiation of white light (sunlight). ... As illumination enters the water, the water consumes white light and reflects just blue light, lights of all colors. The earth from space, thus, looks blue.
