The image below shows part of Lake Mead, the largest reservoir in the United States. Notice the band of white sediments above the water line. This band is known as the “bathtub ring.”

How do you think the bathtub ring formed?

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the real answer is b. scintillation counter
