WORLD HISTORY

Detailed explanation-1: -Rome developed about 15 miles from where the Tiber River empties4 into the Mediterranean Sea. This distance provided Rome with additional protection, because invaders had to move inland from the coast to arrive in the city.

Detailed explanation-2: -The Tiber connected the city of Rome to Ostia, a vital ancient port. While all roads led to Rome, the Tiber led to the sea. Importers and exporters could move their goods quickly across the Empire and exchange cargo on ships headed across the Mediterranean.

Detailed explanation-3: -It is 252 miles (405 km) long. Twisting in a generally southerly direction through a series of scenic gorges and broad valleys, the Tiber flows through the city of Rome and enters the Tyrrhenian Sea of the Mediterranean near Ostia Antica.

Detailed explanation-4: -In ancient Rome, the Tiber River was a reliable source of fresh water. The Romans used this water to irrigate their farms and provide drinking water for people and animals. Rome was not located at a river delta but developed about 15 miles (25 km) from the Tiber River flows into the Mediterranean Sea.

Detailed explanation-5: -The fertile soil of the Po and Tiber River Valleys allowed Romans to grow a diverse selection of crops, such as olives and grains. This allowed the empire to have a food surplus to feed its population and trade with other societies. The empire also used the resulting wealth to expand its military strength.
