What best describes a shield volcano?

Answer 1

I have been doing some research on volcanoes. Scientists have not made another name for shield volcanoes yet. I can not believe it. They have them for cinder cone, and composite volcanoes.

Answer 2

A shield volcano is a volcano with shallow-sloping sides. Shield volcanoes normally form from fluid lava flows that can travel long distances across slight inclines, resulting in their relatively flat, broad profile. In contrast, steeply sloped stratovolcanoes better match the popular stereotype of a volcano. Some of the largest volcanoes on Earth are shield volcanoes.

The name derives from a translation of "Skjaldbreiður", an Icelandic shield volcano whose name means "broad shield", from its resemblance to a warrior's shield.

Answer 3

Shield volcanoes are formed by gentle eruptions of basic lava which is runny and flows faster than viscous lava (acid lava). This runny lava flows over a greater area before solidifying, thus explaining the gentle slopes of the volcano. Eruptions are quiet and frequent as gas and steam can easily escape from within the volcano. A very good example is Mauna Loa in Hawaii.

Answer 4

Shield volcanoes ... are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that a a warrior's shield. They are built up slowly by the accretion of thousands of flows of highly fluid basaltic (from basalt, a hard, dense dark volcanic rock) lava that spread widely over great distances, and then cool as thin, gently dipping sheets. Lavas also commonly erupt from vents along fractures (rift zones) that develop on the flanks of the cone. Some of the largest volcanoes in the world are shield volcanoes. In northern California and Oregon, many shield volcanoes have diameters of 3 or 4 miles and heights of 1,500 to 2,000 feet. The Hawaiian Islands are composed of linear chains of these volcanoes including Kilauea and Mauna Loa on the island of Hawaii -- two of the world's most active volcanoes. The floor of the ocean is more than 15,000 feet deep at the bases of the islands. As Mauna Loa, the largest of the shield volcanoes (and also the world's largest active volcano), projects 13,677 feet above sea level, its top is over 28,000 feet above the deep ocean floor.

Answer 5

Some shield volcanoes include Mauna Loa and Kilauea in Hawaii, Erta Ale in Africa, Español anf Fernandina in the Galapagos, and Olympus Mons on Mars.

Answer 6

D.

formed from repeated explosive eruptions of flowing lava

a volcano that is covered in hardened pahoehoe lava flows.
A shield volcano is best identified by its shallow slopes, and, if active, by its low viscosity water-like lava.

Answer 7

One of the names of shield volcanos is Mauna Loa and Prestahunkur.

Answer 8

a broad gently sloping volcano formed by quiet eruptions of basaltic lave

Answer 9

They are large volcanoes with shallow sloping sides.

Answer 10

A shield volcano is a volcano with gentle slopes, usually composed of basalt from relatively runny lava flows.
