उत्तर
| S.No. | Shield Volcano | Volcanic Dome |
| (i) | Shield volcanoes are formed by intense viscous lava. | A lava dome (or) A volcanic dome is a roughly circular mound formed due to the slow ejection of viscous lava from a volcano. |
| (ii) | These are shallow depositions with gently sloping sides. Hence, the lava flows out in all directions to create a shield. E.g., Mauna Loa, Hawaii. | As the lava is rich in silica with intense viscosity, it is prevented from flowing far from its vent, e.g., Parícutin, Mexico. |
