Question 1

True or false: The Strait of Gibraltar is home to a unique species of penguin found nowhere else on Earth.

Question 2

True or false: The Strait of Gibraltar is the only natural connection between the Atlantic Ocean and the Mediterranean Sea.

Accepted Answer

True. The Strait of Gibraltar is the only natural waterway linking the Atlantic Ocean and the Mediterranean Sea. At its narrowest, it's just 14 km wide.

Question 3

True or false: It is possible to see Africa from Europe with the naked eye on a clear day across the strait.

Accepted Answer

True. Yes, from Tarifa, Spain, you can see Morocco's coast. The strait is only 14 km wide at its narrowest point.

Question 4

True or false: The Strait of Gibraltar connects the Atlantic Ocean to the Mediterranean Sea.

Accepted Answer

True. The Strait of Gibraltar is the natural channel linking these two bodies of water, with Spain to the north and Morocco to the south.

Question 5

Question 6

True or false: The Strait of Gibraltar has a maximum depth exceeding 2,000 meters.

Accepted Answer

False. The maximum depth of the Strait of Gibraltar is around 900 meters, not exceeding 2,000 meters. Deeper straits exist, like the Strait of Magellan.

Question 7

True or false: The waters of the Atlantic and Mediterranean mix perfectly, creating uniform salinity throughout the strait.

Accepted Answer

False. They don't mix uniformly. Atlantic surface water flows in, while denser Mediterranean water flows out deep below, creating distinct layers.

Question 8

True or false: The Strait of Gibraltar is entirely located within Spanish territorial waters.

Question 12

True or false: Swimming across the Strait of Gibraltar is illegal.

Accepted Answer

False. Swimming across the Strait of Gibraltar is legal, though extremely dangerous due to strong currents and heavy ship traffic. Many people have completed the crossing.

Question 14

True or false: The Strait of Gibraltar once completely dried up during the Messinian salinity crisis about 5.9 million years ago.

Accepted Answer

True. Tectonic shifts closed the strait, evaporating the Mediterranean into a salt desert. It refilled dramatically in the Zanclean flood.

Question 15

True or false: Two massive underwater pillars, the Pillars of Hercules, are visible above water at the strait.
