Exploring Sunken Cities

The video explores the underwater remains of ancient Alexandria, Egypt, and discusses real sunken cities like Port Royal and Pavlopetri. It highlights the causes of submersion, such as earthquakes and isostatic sea level changes, and examines the implications of rising sea levels due to global warming on modern coastal cities.

What notable structure once stood on the island across the bay from the Great Harbor in Alexandria?

• The Great Lighthouse

• The Hanging Gardens

• The Great Pyramid

• The Colossus of Rhodes

Which city was known as one of the richest ports in the world before it sank?

• Venice

• Port Royal

• Alexandria

• Helike

What natural disaster caused the Greek city of Helike to sink?

• Volcanic eruption

• Earthquake and tsunami

• Hurricane

• Flood

What do scientists hope to learn from studying sunken cities?

• The development of ancient languages

• The history of ancient wars

• The lives of our ancestors and the planet's dynamics

• The evolution of marine life

What stopped at 11:43 during the sinking of Port Royal?

• A sundial

• A ship's clock

• A pocket watch

• A church bell

What is the term for the process that caused Pavlopetri to submerge?

• Isostatic sea level change

• Erosion

• Tectonic shift
