The geographical features of Ancient Greece included various mountains and hills, volcanoes and the numerous islands that interspersed the country along the Mediterranean Sea. Greece is home to the Pindus Mountain Range, which is the site of one of the planet's deepest canyons, Vikos Gorge. Another major landform in Greece is Mount Olympus, which was considered by the Ancient Greeks as the dwelling of their gods and goddesses.
The rugged mountains of Ancient Greece became suitable for the creation of city-states, which became the main political units of the country. The abundance of coastline and the thousand islands that dotted the region were utilized by the Greeks for fishing, trading and even raiding other villages. The frequent occurrence of earthquakes triggered by an active volcanic zone influenced the Ancient Greeks' belief in oracles.
