Question 1

True or false: Lake Erie is the shallowest of the five Great Lakes, making it also the warmest in summer.

Accepted Answer

True. True. Its average depth is only 62 feet, which allows it to heat up quickly, creating prime conditions for algae blooms.

Question 2

True or false: Lake Erie is the smallest by volume of all five Great Lakes, holding less water than Lake Ontario.

Accepted Answer

True. True. Lake Erie's volume is about 484 km³, the smallest of the Great Lakes. Lake Ontario holds roughly 1,640 km³, significantly more due to its greater depth.

Question 3

True or false: The Cuyahoga River, which flows into Lake Erie, caught fire in 1969 due to industrial pollution.

Accepted Answer

Question 4

True or false: Lake Erie is the only Great Lake where you can find a naturally occurring freshwater coral reef.

Accepted Answer

False. False. While Lake Erie has unique rock formations and reefs, true coral reefs are saltwater only; no Great Lake has them.

Question 5

True or false: Lake Erie's shoreline is entirely within the United States, with no Canadian border touch.

Accepted Answer

False. False. Lake Erie is shared by the U.S. (Ohio, Pennsylvania, New York, Michigan) and Canada (Ontario), with the border running through the lake.

Question 6

True or false: Lake Erie is the only Great Lake that does not have a native population of lake sturgeon.

Accepted Answer

False. Lake sturgeon are native to Lake Erie, but overfishing and habitat loss nearly wiped them out—they're now making a comeback.

Question 7

True or false: Over half of the fish species in Lake Erie are non-native invasive species introduced by ships.

Accepted Answer

False. False. Non-native fish make up only about 10–15% of the lake’s 130+ species. Invasive fish like round goby and sea lamprey are a small fraction, though ecologically significant.

Question 8

True or false: The lake's nickname 'Erie' comes from a Native American word meaning 'long tail' due to its shape.

Accepted Answer

False. False. 'Erie' comes from the Erie people, whose name means 'cat' or 'long tail' in Iroquoian, but it refers to the tribe, not the lake's shape.
