Question

why the earth seems blue from the space​

Answer 1

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. Closer to the horizon, the sky fades to a lighter blue or white.

Answer 2

The Earth seems to be blue from space because the majority of the Earth is covered in water.Thus, the Earth looks like a blue ball from the space.
