Which resource would best the student understand the meaning of the volcano's flanks

This discovery activity puts students in the place of real volcanologists by giving them access to real-time data from Kilauea Volcano, Hawaii. They learn about volcano monitoring techniques, study case histories of important volcanic processes, and then form and test hypotheses for past and future volcanic events with multiple instruments and real-time data. As a result, students will understand the processes that shape a basaltic shield volcano.

Since you said "which", are there options?
