Which outcome consistently results from effusive lava eruptions?

💡 Explanation

Effusive eruptions create broad, gently sloping shield volcanoes because low-viscosity lava spreads over large areas via magma convection; therefore, shield volcanoes form, rather than violent pyroclastic surges typical of explosive eruptions.
