1. BLOOD FALLS IS AN ON-AGAIN-OFF-AGAIN flow of red-orange water—striking against Antarctica’s sweeping grayscape—from the toe of Taylor Glacier, not far from McMurdo Station research base.
A. True
B. False
2. The Taylor Glacier is so cold that it really shouldn’t have any liquid water flowing through it at all.
A. True
B. False
3. Taylor Glacier is now the coldest known glacier to have persistently flowing water.
A. True
B. False
4. Scientists found that the saltiness of the water (which lowers the freezing temperature) and the latent heat of freezing—which is definitely a thing—helps explain how Blood Falls keeps flowing.
A. True
B. False
5. The red color in the blood falls comes from iron in the salty water, which is thought to originate from a pocket of brine trapped deep beneath the glacier for more than a million years (and supporting its own, unique microbial ecosystem).
A. True
B. False
Best of luck!
