Who is the goddess of earth and Thor's wife?

Who is the goddess of earth and Thor’s wife? Sif is Thor’s golden-haired wife and a Norse goddess associated with the earth. Her name is especially connected with her marriage to Thor and with imagery of fertility and cultivated land.

Sif is attested in the Poetic Edda and Prose Edda, where she is described as Thor’s wife and the mother of Þrúðr. She is also the mother of Ullr, although the surviving myths do not identify Ullr’s father. Her most famous story begins when Loki cuts off her hair.

Thor demands a replacement, so Loki obtains magical golden hair from dwarfs. The episode leads to the creation of several famous treasures, including Odin’s spear Gungnir and Thor’s hammer Mjölnir. Sif’s golden locks are often interpreted as a poetic image of ripe grain or fields.

A frequent confusion is with Jörð, whose name literally means “Earth” and who is Thor’s mother. Sif is Thor’s wife; Jörð is the personification of Earth. Older scholarship and poetic associations can connect Sif with fertility and earth, which explains the wording of this question.
