Live Game Live. Shield volcanoes are characterized by eruptions that are very hot and have a very low silica content. cone.. when a strato volcano erupts vast amounts of gasses such as What was the weather in Pretoria on 14 February 2013? The two types of volcano form in different places and have very different characteristics.

A volcano is an opening in Earth's crust where magma breaks through, raining down molten rock, ash and gases. Airborne fragments of lava, called tephra, are ejected from a single vent. Like shield volcanoes, stratovolcanoes are polygenetic; however, they differ from shield volcanoes in that they erupt infrequently, with typical repose intervals of hundreds of years between eruptions. Volcano Learning Zone > Types of volcano > Stratovolcano. Mount Fuji, an active stratovolcano in Japan that last erupted in 1707–08. Shield Volcano Stratovolcano 7 Shield Volcanoes: • Low Viscosity, • Low Volatiles, • Large Volume • Gently sloped, broad-based island volcanic peaks • Composed of basaltic lava • Eruptive styles Hawaiian or Icelandic Shield Volcanoes 8 The stratovolcano may not be as geologically pronounced as a hot-spot volcano which can form an elongated set of islands, as the Hawaiian chain of islands. A shield volcano has shield-like shape. Homework. It has some of the oldest cones, aligned northwest-southeast, ending on the destroyed Las Nubes volcano crater (Bergoeing, 1979). It is built up of many layers of hardened lava, tephra, pumice, and volcanic ash.. Unlike flat shield volcanoes like in Hawaii, they have higher peaks. V. VEI Vent This allows the lava to flow outward like a superheated river for long distances rather than stacking up on top of itself. Copyright © 2021 Multiply Media, LLC. Meanwhile, shield volcanoes have very fluid lava (low viscosity) that can travel very far during eruptions, and this accumulates as broad, gently-sloped layers that look like a 'shield'. Shield vs Stratovolcano DRAFT. Shield volcanoes are short and round because when they erupt, lava typically flows out from the summit crater due to the fluid-like consistency of the lava. Strato volcanoes have steep slopes, shaped like a tall narrow rivers of lava run down the sides of the volcano. Rainier, may be more than 1 million years old. The lower part of the mountain in some areas is clearly a shield on top of which a stratovolcano has built, but I would best describe it as a complex volcano. To play this quiz, please finish editing it. A stratovolcano is a tall, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. Shield Volcanoes Stratovolcanoes Greatest Volcanic Eruption Iceland Volcano. Shield volcanoes quietly produce broad, massive structures through lava flows. [1] Unlike shield volcanoes , stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions , although some have collapsed summit craters called calderas . There are three primary types of volcanoes, each with unique physical characteristics and eruptive natures.
