Answer:
The European Age of Exploration began in the late 1400s. The
earliest explorers did not set out to find new continents. They sailed unknown seas,
looking for routes to Asia. Europeans wanted spices and silks from Asia. Merchants
from Italy and the eastern Mediterranean controlled this trade. To share in this
business, other countries sought their own trade routes. Thus, the Age of
Exploration was born.
Few people in the 1400s had traveled far from Europe. Then, in 1492, Christopher
Columbus sailed to North America. Other explorers followed. They used special
navigation tools to help them cross the ocean. They brought back things of value.
Sometimes, ships were lost at sea. Today, scientists search for these sunken
ships. They study artifacts that remain at the wrecks. These objects tell us about the
explorers’ expeditions.
