Shield volcanoes are large for the following reasons (choose two): Group of answer choices. the lava has low viscosity and so flows far and covers a wide area. the lava source is from the mantle. This thick layer held under pressure provides an abundant supply of magma and lava. A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in … See more The term 'shield volcano' is taken from the German term Schildvulkan, coined by the Austrian geologist Eduard Suess in 1888 and which had been calqued into English by 1910.
