Which type of volcano forms broad, gently sloping domes from low-viscosity basaltic lava?

The Ring of Fire traces the outer boundary of which major ocean?
About 75% of Earth's active volcanoes sit along the basin of the Pacific Ocean in the Ring of Fire.
Along the Ring of Fire, which tectonic process drives volcanic activity?
Dense oceanic plates sink beneath lighter continental plates, melting rock into magma that feeds the arc's volcanoes.
The Ring of Fire produces roughly what percentage of Earth's earthquakes?
Movement along subduction zones makes the Ring of Fire home to 90% of the world's quakes and 81% of the largest ones.
Ring of Fire subduction zones carve which steep seafloor feature?
Sinking plates pull the seafloor downward, carving steep trenches like the Mariana Trench alongside the volcanic arcs.
