Question

During the 1960s, geologists used seismometers to record information that suggested Earth's plates were in motion. The data recovered by the seismometers showed that earthquakes, volcanoes, and other geologic features tend to occur or be present
A.
around the centers of tectonic plates.

B.
on the edges of tectonic plates.

C.
in Earth's outer core.

D.
in Earth's inner core.

B. on the edges of tectonic plates.

Seismometer records show earthquakes, volcanoes, and related features cluster at plate boundaries, where plates interact (convergent, divergent, transform), not at plate centers or in the deep core.
