Problem:The Hughes H-4 Hercules (also known as the Spruce Goose; registration NX37602) is a prototype strategic airlift flying boat designed and built by the Hughes Aircraft Company. Intended as a transatlantic flight transport for use during World War II, it was not completed in time to be used in the war. The aircraft made only one brief flight on November 2, 1947, and the project never advanced beyond the single example produced. Built from wood because of wartime restrictions on the use of aluminum and concerns about weight, it was nicknamed by critics the Spruce Goose, although it was made almost entirely of birch. The Hercules is the largest flying boat ever built, and it has the largest wingspan of any aircraft that has ever flown. The aircraft remains in good condition. After being displayed to the public for almost 11 years in Long Beach, California from 1980 to 1991, it is now displayed at the Evergreen Aviation & Space Museum in McMinnville, Oregon, United States.

Student A:In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.

Based on this passage, where are most of the divergent boundaries found?
Student B:OK... To answer the question, consider the following: Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.
between oceanic plates.
