Final answer:
The three generations of Greek gods are the Primordials, Titans, and Olympians. The Olympians, including Zeus and Hera, are the best-known group and resided on Mt. Olympus.
Step-by-step explanation:
The names of the three generations of Greek gods are Primordials, Titans, and Olympians. The Primordial gods were the first deities, including Gaia (Mother Earth) and Uranus (Father Sky), and they gave birth to the Titans, who were the second generation of gods and included twelve male and female giants. The third generation, known as the Olympians, overthrew the Titans and consisted of the most well-known Greek gods who resided on Mt. Olympus, like Zeus, Poseidon, and Hera. These gods played essential roles in Greek mythology, with heroes like Perseus and Hercules being influenced by their divine actions.
