It would be wrong to state that earth and world both have a definite full form. … World – There is no full form for world as it basically means the place where we live. All countries, continents and everything on this earth constitutes the world.
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
The English name, from the 15th century, for the planet we inhabit came from the Old English eorþe, meaning both “ground, soil, dirt, dry land; country, district” and “the material world, the abode of man”, which descended from the Proto-Germanic erþ ō, from the Proto-Indo-European root er- (“earth”, “ground”).
Pangea’s existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”
Earth, “Tellus”, in ancient Rome was the personification of the nurse Earth, sometimes honored under the name of Terra Mater (Mother Earth), mostly identified with the Greek goddess Gaia (Gea). The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil.
