How did geography affect the development of civilization in Greece and Italy?

The Etruscans changed Rome from a village of straw-roofed huts into a city of wood and brick buildings. They laid out streets, temples, and public buildings around a central square.

Edit: The above one doesn't relate to geography though, and it doesn't mention Greece. Here is my answer:

The landscape of Italy is similar to that of Greece, but the Apennines are not as rugged as Greece's mountains. As a result, the people in Italy were not split up into small, isolated communities like the Greeks. Italy had better farmland than Greece. With more capacity to produce food, Italy could support more people than Greece could.
