Who were the gods of sea land and sky?

In ancient mythology, particularly in Greek mythology, the gods of the sea, land, and sky were Poseidon, Zeus, and Hades, respectively. Poseidon ruled over the sea and was known for his control over water and earthquakes. Zeus was the king of the gods and governed the sky, wielding thunder and lightning. Hades, although less commonly associated with the earth itself, ruled the underworld and was often connected to the land through his dominion over the dead.
