Base your answers to questions 70 through 74 on the passage and data tables below, on the map in your
answer booklet, and on your knowledge of earth science. the data tables show trends (patterns) of two lines of
hawaiian island volcanoes, the loa trend and the kea trend. for these trends, ages and distances of the
hawaiian island volcanoes are shown. the map shows the locations of volcanoes, labeled with xs, that make up
each trend line.
hawaiian volcano trends
the hawaiian volcanic island chain, located on the pacific plate, stretches over
600 kilometers. this chain of large volcanoes has grown from the seafloor to heights
of over 4000 meters. geologists have noted that there appear to be two lines, or
“trends,” of volcanoes—one that includes mauna loa and one that includes mauna
kea. loihi and kilauea are the most recent active volcanoes on the two trends shown
on the map

identify the tectonic feature beneath the moving pacific plate that caused volcanoes to form in both the loa and kea trends.
