The water appears blue because it is reflecting the sunlit atmosphere from the relative perspective of the surface of the Earth. (There are other reasons too.)
The Earth is blue because the O-zone layer is blue and creates the dominant color in the earth's atmosphere so that even from space the earth appears blue
The blueness you see on the Earth from space is the oceanic water.
It's the water, and the green is land.
Well to begin with, the blue you see in pictures from outer space are the oceans. The sky really isn't blue; it is the reflection of a certain wavelength of light (Blue) off of the particles in the air. So the atmosphere is essentally clear.

because most of the earth's surface is covered by water, so from space it looks blue.
Astronomy is the study of the outer space. If you look up at the sky at night you are looking at outer space which is astronomy.
An observatory
1. Outer space contains virtually no gas/dust to scatter light. Outer space is black. 2. The sky is blue because that's the colour of air (mostly nitrogen), which is not totally colourless. You can see this effect looking at distant (10 km-plus) mountains. They have a blue tinge (caused by the intervening air between you and the mountains) known as atmospheric perspective. 3. If the sky's colour was due reflection from the oceans, then it would be white above Antarctica, which is snowy white. 4. If the ocean was blue because it reflects the sky, why does it still look blue-ish when under a totally clouded-over sky? The ocean is blue for the same reason the sky is blue: the sky is blue 'cause that's the colour of air, the sea is blue 'cause that's the colour of water.
Yes but no , the blue whale is blue & gray but they look a fine lite blue under the sea.
The water is reflecting the blue sky.
roll down the window and look for a gas station if you run out of fuel
