Pagan Celebrations: 8th of March is the Birthday of Mother Earth
The name derives from the Indo-European basis of the Germanic noun eor(th)e Dutch: aarde, Danish, Swedish: jord, English: earth. Like most words and names, the Earth has its unique name in many different languages around the world.
GAIA (Gaea) is the goddess of the earth.
She is one of the primoridal elemental deities (protogenoi) born at the dawn of creation. Gaia is the great mother of all creation--the heavenly gods were descended from her through her union with Ouranos (Uranus) (Sky), the sea-gods from her union with Pontos (Sea), the Gigantes (Giants) from her mating with Tartaros (the Pit), and mortal creatures born directly from her earthy flesh.
Jord
Thors mother, variously named as Jord (Old Norse “Earth”), Hlöðyn, or Fjörgyn, is entirely of giant ancestry. Thor’s mother is also called Fjörgyn, Hlóðynn, Fold, and Grund throughout Eddic and skaldic poetry. These names, like “Jord,” all mean “Earth,”so, given the context, it’s unlikely that they were thought of as being truly distinct personages.
Before the Norse and other Germanic peoples converted to Christianity, their sacred tales and divine personalities were never systematized or rationalized like they are in modern storybook versions of mythology. They wouldn’t have necessarily felt a need to explain exactly who Thors mother was. That She was “Earth” was apparently enough.
The Norse and other Germanic peoples were part of the larger Indo-European group of peoples. Throughout the Indo-European world – for example, among the Celts, Slavs, Greeks, Romans, and early Hindu society – the idea that femininity and the earth are intrinsically connected, as are masculinity and the sky, was one of the most basic and common ideas. This is borne out especially clearly in Celtic mythology (wherein all goddesses, with very few exceptions, conform to the earth/fertility/mother/sovereignty type)
Another Germanic goddess, Nerthus, was specifically identified with the Roman Terra Mater, “Mother Earth,” by the Roman historian Tacitus.
In the New-Age movement
In the New Age movement and in some ecological circles, Gaia is a term for the earth or nature as the "nourishing Mother Earth", conceived as a cosmic, living being. This view is expressed in the Gaia Hypothesis, a hypothesis that the entire globe must be considered a living organism.
