hemispheres--a continent hemisphere and an ocean hemisphere.
The latter, the Pacific hemisphere, is underlain almost entirely by
one gigantic tectonic plate--a continuous chunk of Earth's crust--
which is diving under what is called the ring of fire because of the
volcanoes that line the plate boundary along Oregon, Washington
State, British Columbia, the Aleutians, the Kuriles, Japan, the
Marianas, Tonga-Fiji, South America, and Central America. There
are also volcanoes in other places: along other plate boundaries on
