The key (for the host: fold this page back)
- A: a hotspot in the mantle. The islands get older and more worn down the farther they are from the hotspot.
- C: Mount Chimborazo. Earth bulges at the equator, and Chimborazo sits just one degree south of it.
- A: P waves. P stands for primary; the slower S, or secondary, waves arrive later.
- A: the mantle. NASA compares the hot rock of the mantle to thick, slow-moving caramel.
- C: the Mariana Trench. It is about 10,935 meters deep, in the western Pacific Ocean.
- A: composite volcanoes. They are also called stratovolcanoes, built from layers of lava and ash.
- C: metamorphic rock. Schist and gneiss are metamorphic rocks, often with stripes or bands.
- A: the liquid outer core. The outer core is liquid metal, while the inner core is solid.
