Which lake is famous for its bright blue color and is in Crater Lake National Park?

Easy
A
Lake Tahoe
B
Crater Lake
C
Lake Powell
D
Lake Shasta
Explanation

Crater Lake, located in Oregon, USA, is world-famous for its intense blue color and incredible water clarity. The lake was formed approximately 7,700 years ago when the volcano Mount Mazama collapsed during a massive eruption, leaving a deep caldera that eventually filled with rain and snow. Because it has no inlets or outlets, the water is some of the purest in the world.

Nevada
B
Utah
C
Arizona
D
California
Explanation

The Great Salt Lake is located in the U.S. state of Utah and is the largest saltwater lake in the Western Hemisphere. It is a remnant of the prehistoric Lake Bonneville, which was once a massive freshwater lake covering much of the Great Basin. Because the lake has no outlet, salt and minerals accumulate as water evaporates, making it several times saltier than the ocean.

🌟 Fun Fact

Because the lake is so salty, the only things that can live in its water are tiny brine shrimp and salt-tolerant algae!

6

Medium
A
California
B
New York
C
Florida
D
Texas
Explanation

The Finger Lakes are a series of eleven long, narrow, roughly parallel lakes located in the central part of the U.S. state of New York.

18

Which lake is known for its 'Floating Islands'?

Hard
A
Lake Tahoe
B
Lake Titicaca
C
Lake Superior
D
Lake Victoria
