Which process limits the eruption intensity at shield volcanoes?

💡 Explanation

Low-silica magma allows dissolved gases to escape more easily via the mechanism of effusive eruption, because the lower viscosity prevents pressure build-up; therefore, eruptions are less explosive with less volcanic intensity, rather than high silica lavas which cause explosive eruptions that builds pressure significantly.
