Geography has a few effects on the Greeks and the world. Some of the effects are developments of ancient Egypt and having relationships with other city-states.
Their geography was rocky soil but grapes can grow in rocky soil so they made wine and grapes and also olive oil
Because the Greeks farted in jars and ate doody
the Greeks were forced to move towards the ocean since the terrain was so rocky
islands,many coasts,it is mainly a sea country
im pretty sure it helped their city-states fiercely independent
Plays, poetry, histories, and inscriptions.
The geography of Greece is very mountainous with many valleys around them making it hard for other city states to come and attack them.
The mountainous geography kept the Greeks from uniting.
it was not the Geography of Greece which influenced western civilisation. It was Greek civilisation and the fact that the Greeks migrated out of Greece. They migrated to western Turkey, southern Italy and Sicily and they founded Marseilles in southern France. Thus, they created a Greek world which extended beyond mainland Greece. The Greeks influenced the peoples who lived near then. They also influenced the Romans. It is though this influence of the Romans that the Greeks later influenced western civilisation.
Take the Romans for example. If you don't know where or what Rome is then you will struggle knowing where this tribe started and originated from. It is the same with: The Greeks The Egyptians The Chinese The Indian The Norwegians Etc.
Greek geography has much to do with the way early Greeks lived. Mainland Greece lies on the southern part of the Balkan Peninsula.
