Earth Seen From The Moon



Earth is comprised of over two thirds ocean and many contintents which have evolved over the life of the planet and its tectonic plates (primary, tertiary and secondary).  Primary plates are (African Plate, Antarctic Plate, Eurasian Plate, Indo-Australian Plate, North American Plate, Pacific Plate, South American Plate).  365 days make up a Solar Year.  The planet is 4.54 billion years old.  The Earth is orbited by the moon which is theorized to have been formed a few hundred years after the Earth due to a large collision.
