Which outcome occurs after magma reaches strength threshold?

💡 Explanation

Higher magma viscosity enables plugging, therefore a lava dome is formed during viscous magma extrusion because it can withstand the pressure, increasing speed, rather than causing caldera collapse or altering tephra fallout.
