Question

North America and South America are joined by the __________________.
A.Suez Canal
B.Bering Strait
C.Strait of Gibraltar
D.Isthmus of Panama

Answer 1

Hint: The continent of North America is the northern subcontinent of the Americas and the continent of South America is the southern subcontinent of the Americas, both located in the western hemisphere. Moreover, both these continents are bound by the Atlantic Ocean on the east and the Pacific Ocean on the west. To the north of North America are the Arctic Islands and the north pole while further south of South America is the continent of Antarctica and the south pole. They are joined by a narrow passage of land between the Caribbean Sea and the Pacific Ocean.

Complete answer: Option A: is incorrect. The Suez Canal is an artificial waterway that connects the Mediterranean Sea and the Red Sea. It was built through Isthmus of Suez in Egypt in 1869 effectively connecting Africa and Asia and serving as a quick route for trade.
Option B: is incorrect. The Bering Strait is a narrow passage of water located in the Pacific Ocean that separates the countries Russia and the USA. It is named after a Danish explorer who discovered the strait in 1728 while serving the Russian Empire.
Option C: is incorrect. The strait of Gibraltar is a narrow passage of water that connects the Mediterranean Sea to the Atlantic Ocean. It is located between the edge of the Iberian Peninsula in Europe and Morocco in Africa.
Option D: is correct. The Isthmus of Panama is a naturally occurring passage of land that connects the continents of North America and South America and separates the Atlantic Ocean on its east from the Pacific Ocean on its west.

Thus, The correct answer is Option D.

Note: The Americas were discovered by West European countries during the Age of Discovery by several voyages during the early 16th century, the most famous of which were the ones taken by Italian explorer Christopher Columbus. However, the theory suggests that hunters from Siberia entered through the Beringia land bridge almost 15,000 years ago.
