While researching a topic, a student has taken the following notes:
· Grand Prismatic Spring is a geothermal feature located in Yellowstone National Park.
· It is the largest hot spring in the United States and the third largest in the world.
· The spring's vivid colors are caused by microbial mats that thrive in the hot water.
· These mats produce bright hues of orange, yellow, and green, which contrast with the deep blue of the spring's center.
· The water temperature in the center of the spring is too high to sustain microbial life.
The student wants to explain what causes the striking colors of Grand Prismatic Spring. Which choice most effectively uses relevant information from the notes to accomplish this goal?
