Earth, as viewed from space, is a mixture of green, brown, blue and white. Each one of these colors is representative of a different part of the Earth's crust.
When viewed from space, the green and brown colors that can be seen are the land masses. Depending on the dryness or fertility of the land, every land mass is some shade of green or brown. The blue color is the water sources of the planet. This includes oceans, lakes and rivers. The white colors are the clouds in the sky or polar ice. Most areas of cloud coverage are small, but large cloud coverage could be the evidence of a storm.
