Distinguish between Shield Volcano and Volcanic Dome.

Answer»

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