Italian Peninsula
A peninsula in southern Europe extending into the Mediterranean Sea. It contains most of Italy, along with San Marino and Vatican City.
Apennine Mountains: A mountain chain running the length of the Italian Peninsula, from the northwest toward Calabria. This range forms the peninsula’s central spine and divides many of its regions.
African Plate: A major tectonic plate that underlies Africa and parts of the surrounding ocean floor. Its convergence with the Eurasian Plate helps drive tectonic activity beneath Italy.
Sicily: The largest island in the Mediterranean Sea, separated from mainland Italy by the Strait of Messina. It lies just off the peninsula’s toe and is often grouped with Italy’s mainland regions.
Ancient Rome: The civilization centered on Rome that grew from a city-state into an empire across the Mediterranean world. Rome’s central location on the peninsula supported its expansion across surrounding seas.
Po Valley: A broad, fertile plain in northern Italy drained chiefly by the Po River. It is the peninsula’s largest lowland, set between the Alps and northern Apennines.
Eurasian Plate: A major tectonic plate comprising most of Europe and Asia. Its interaction with the African Plate contributes to uplift and seismicity around the peninsula.
Calabria: A region occupying the toe of the Italian boot, between the Tyrrhenian and Ionian seas. Its narrow, mountainous terrain forms the peninsula’s southernmost mainland region.
Roman Empire: The state ruled by Roman emperors, at its greatest extent controlling territories across Europe, North Africa, and western Asia. The peninsula became the empire’s political center and chief point of reference.
Tyrrhenian Sea: A part of the Mediterranean Sea between the Italian Peninsula, Corsica, Sardinia, and Sicily. It borders the peninsula’s western coast.
Subduction: The process in which one tectonic plate moves beneath another into the mantle. Subduction around Italy helps explain its active volcanic and earthquake zones.
