Which body of water does the Channel Tunnel pass under?

The Channel Tunnel, often referred to as the Chunnel, is a remarkable engineering feat that runs beneath the English Channel. This tunnel connects Folkestone in the UK with Coquelles near Calais in France. The English Channel is the body of water that separates southern England from northern France, making it the correct answer.

This channel has historical significance as a major route for ferries and shipping between the UK and mainland Europe. The construction of the Channel Tunnel, completed in 1994, was aimed at enhancing transportation links, and it consists of a 50.45 km (31.4 miles) long tunnel, significantly facilitating both passenger and freight transit.

The other bodies of water mentioned, such as the Atlantic Ocean, North Sea, and Mediterranean Sea, are geographically separate from the Channel Tunnel's location and do not pertain to its routing. The Atlantic Ocean lies to the west of the UK and France, while the North Sea is located to the northeast of England. The Mediterranean Sea, on the other hand, is situated much further south and does not lie in proximity to the English Channel. These geographical distinctions highlight why the English Channel is the correct body of water for the Channel Tunnel.
