lakebeds
Underwater basin floors
Lakebeds are the floors of lakes—the ground beneath the water.
When lakes dry up, their lakebeds become exposed terrain, often flat and silty: The ancient lakebed revealed fossils millions of years old.
Geologists study lakebeds for evidence of past climates and water levels.
