Who was the goddess who caused changes in the seasons?

The goddess who caused changes in the seasons is Demeter in Greek mythology. She is the goddess of agriculture, fertility, and the harvest, and her relationship with her daughter Persephone explains the seasonal cycle. When Persephone is in the Underworld with Hades, Demeter grieves, leading to winter; when Persephone returns to the surface, Demeter rejoices, and spring and summer follow. This myth symbolizes the agricultural cycle and the connection between life, death, and rebirth.
