Question 1

True or false: The Chesapeake Bay Bridge-Tunnel was the longest bridge-tunnel complex in the world when it opened in 1964.

Accepted Answer

True. Opened on April 15, 1964, the 17.6-mile Chesapeake Bay Bridge-Tunnel was the world's longest bridge-tunnel complex at that time, combining trestles, bridges, and tunnels.

Question 2

True or false: Chesapeake Bay water is saltier than the open Atlantic Ocean due to evaporation in the shallow estuary.

Accepted Answer

False. Bay water is brackish—less salty than the ocean. Freshwater from rivers dilutes saltwater from the Atlantic, with salinity increasing toward the mouth.

Question 3

True or false: The current oyster population in the Chesapeake Bay can filter all the bay's water in less than a week.

Accepted Answer

False. Historically, oysters filtered the entire bay in days. But due to overharvesting and disease, the current population would take over a year to do so.

Question 4

True or false: The Chesapeake Bay is home to the oldest continuously operating lighthouse in the United States.

Accepted Answer

False. The oldest continuously operating lighthouse in the United States is Boston Light on Little Brewster Island in Massachusetts, dating to 1716. The Chesapeake Bay’s Thomas Point Shoal Lighthouse (1875) is not the oldest.

Question 5

True or false: The Chesapeake Bay watershed is home to more than 350 species of fish.

Accepted Answer

True. The Chesapeake Bay watershed supports an incredible diversity of aquatic life, including over 350 documented fish species, making it one of the most productive estuaries in the world.

Question 6

True or false: Chesapeake Bay's blue crab population has never recovered from a 1990s crash and remains critically endangered.

Accepted Answer

False. While blue crabs faced declines, recent population surveys show healthy rebounds thanks to management, and they are not critically endangered—still sustainably harvested.

Question 7

True or false: Chesapeake Bay was formed by a meteor impact 35 million years ago, creating its distinctive shape.

Accepted Answer

False. The bay was formed by rising sea levels flooding the Susquehanna River valley after the last ice age, not a meteor impact. A buried impact crater from 35 million years ago lies beneath, but it did not directly create the bay's shape.

Question 8

True or false: The Chesapeake Bay's deepest point, called 'The Hole,' is over 200 feet deep off Maryland's coast.

Accepted Answer

False. The deepest natural point, 'The Hole' off Bloody Point, MD, is about 174 feet deep, not over 200 feet.
