How did the geography and climate of Italy influence the development of Ancient Rome?

Rome was located on seven hills which  were easy to cross because they are not so tall like the Greek mountains. The geographical location of the city (Rome) and mountains was excellent because they were far enough from the sea  and the attacks of the pirates. The Tiber River supplied the Romans with fresh water and food. The Roman people could cross the river easily. In addition to these facts,  the farming in Italy was good, which helps explain why many people came to live in Italy (Rome). Italy also had the high Alps in the north which helped to protect them from European attacks from that direction.
