USA HISTORY

Detailed explanation-1: -Columbus knew that the world was round and realised that by sailing west-instead of east around the coast of Africa, as other explorers at the time were doing-he would still reach his destination.

Detailed explanation-2: -Contents. The explorer Christopher Columbus made four trips across the Atlantic Ocean from Spain: in 1492, 1493, 1498 and 1502. He was determined to find a direct water route west from Europe to Asia, but he never did. Instead, he stumbled upon the Americas.

Detailed explanation-3: -With a crew of 90 men and three ships-the Niña, Pinta, and Santa Maria-he left from Palos de la Frontera, Spain. Columbus reasoned that since the world is round, he could sail west to reach “the east” (the lucrative lands of India and China).

Detailed explanation-4: -In 1271, Marco Polo, along with his uncle and father, left their home of Venice and headed east, traveling to Acre, Hormuz, and then Shangdu to the court of the Mongol emperor of China, Kublai Khan. After 20 years in China, the Polo family returned to Venice by sailing along Southern Asia.
