The ocean that connects Europe and America is the Atlantic Ocean.
Here's a simple explanation: The Atlantic Ocean is a massive body of water that lies between the continents of Europe and Africa to the east and the Americas to the west. This ocean is one of the world's five major oceans and is the second largest after the Pacific Ocean. Historically, the Atlantic Ocean has been significantly important as a route for ships traveling between Europe and the Americas, playing a crucial role in exploration, commerce, and cultural exchanges.
