Because that is what it looks like from space.
Earth appears blue from space because of its oceans, which cover about 71% of its surface. This vast amount of water reflects and scatters sunlight, giving the planet its characteristic blue appearance. Additionally, the Earth's atmosphere also scatters sunlight, which further contributes to the blue hue when viewed from space.
Limestone changes into marble through a process called metamorphism. This process involves the recrystallization of the calcite mineral in limestone due to high pressure and temperature deep within the Earth's crust. This transforms the limestone into a more compact, harder, and denser rock known as marble.
Marble can turn back into limestone through a process called metamorphism. When subjected to high pressure and temperature underground over long periods of time, the minerals in marble can recrystallize and rearrange to form limestone. This transformation occurs in the Earth's crust, where the conditions favor the alteration of marble back into limestone.
Marble is formed from limestone that undergoes a process called metamorphism. This process involves high pressure and temperature deep within the Earth's crust, causing the limestone to recrystallize and form marble. The key processes involved in its creation are heat, pressure, and the presence of fluids that help facilitate the transformation of limestone into marble.
Marble that was once sedimentary rock is called metamorphic marble. It forms when limestone, a sedimentary rock, undergoes metamorphism due to high pressure and heat, which causes its minerals to recrystallize into marble.
Earth is called the "Big Blue Marble" because when viewed from space, it appears as a blue sphere covered mostly by water. The oceans and atmosphere give the planet its distinctive blue color, likening it to a "marble" floating in space.

Yes, the term "blue marble" is often used to describe photographs of Earth taken from space that show the planet predominantly covered in blue due to its oceans. It is a way to symbolize Earth's beauty and fragility.

I'm guessing you mean the "Blue Marble," which is a famous shot of the Earth taken from space. The oceans of the world, combined with swirling cloud cover made the Earth look like a blue marble. Read more here: http://en.wikipedia.org/wiki/The_Blue_Marble
In space, the Earth looks like a blue marble. NASA has many photographs of the Earth from space. The earth is spherical like an orange but it is not orange.http://eol.jsc.nasa.gov/Collections/EarthFromSpace/land.htmhttp://www.wired.com/2014/12/digital-globe-best-earth-from-space-201
The Blue Marble - album - was created in 1969.
All colors are absorbed by a blue marble except the color blue because it is reflected.
Big Blue Marble ended on 1983-01-01.
Big Blue Marble was created on 1974-09-21.
We are called Earth. "Blue Planet" is a nickname for Earth, since our planet comprises primarily of water.
Earth as a Blue Marble relates to a picture taken on December 7, 1972, by the crew of the Apollo 17 spacecraft at a distance of about 45,000 kilometres (28,000 mi). The crew had their back to the sun so the Earth was fully illuminated. Similar pictures have been taken since that time. The phrase is used and popularized in Carl Sagan's documentary/science series "Cosmos" to represent the beauty and smallness of our planet in relation to the Universe.
