The key (for the host: fold this page back)
- B: petrification. Water seeps into buried bone and leaves minerals behind, turning it to stone.
- A: wind shear. Wind shear helps set up the spinning air inside storms that can form tornadoes.
- C: the Challenger Deep. It lies at the southern end of the Mariana Trench in the western Pacific.
- C: Earl Douglass. His first find there was eight connected tailbones of an Apatosaurus.
- C: deposition. Sublimation is the opposite, when ice turns straight into vapor.
- B: the temperature of the eggs. Scientists call this temperature-dependent sex determination, or TSD.
- C: the lizard-hipped saurischians. The hip names were chosen before scientists knew birds are dinosaurs.
- B: 35 miles per hour. The snow must also cut how far you can see to under a quarter mile, for more than 3 hours.
- A: calcium carbonate. Most stony coral polyps are only one to three millimeters across.
- B: 🦁 A lion. A riddle: every clue fits only one of the three.
