Some of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.
.
Besides, what type of lava does a stratovolcano have?
A stratovolcano is a tall, conical volcano composed of one layer of hardened lava, tephra, and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions. The lava that flows from them is highly viscous, and cools and hardens before spreading very far.
Also, what causes a shield volcano to be shaped like a broad? A shield volcano possesses broad dome and shield-like shape due to the steady flow by flow of lava on the surface of the volcano. The low impact eruptions cause the lava to easily flow and spread out in thin layers.
Additionally, which type of volcano is the largest?
Shield volcanoes
Which type of volcano is most likely to be composed of high viscosity lava?
Composite volcanoes are some of the most dangerous volcanoes on the planet. They tend to occur along oceanic-to-oceanic or oceanic-to-continental boundaries because of subduction zones. They tend to be made of felsic to intermediate rock and the viscosity of the lava means that eruptions tend to be explosive.

Examples of strato volcanoes include Mt. St. Helens, Mt. Rainier, Pinatubo, Mt.What is the most dangerous type of volcano?
Not surprisingly, supervolcanoes are the most dangerous type of volcano. Supervolcanoes are a fairly new idea in volcanology. The exact cause of supervolcano eruptions is still debated, however, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion.Why are Stratovolcanoes so dangerous?
This lava plugs up the plumbing in stratovolcanoes, allowing them to build up tremendous amounts of pressure. Of all the volcanoes on Earth, stratovolcanoes are the most dangerous. They can erupt with little warning, releasing enormous amounts of material. And they don't always erupt nicely from their tops.How is a volcano formed?
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.Where is the Ring of Fire?
The Ring of Fire (also known as the Rim of Fire or the Circum-Pacific belt) is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.Are composite volcanoes explosive?
There are three main types of volcano - composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. Eruptions are explosive due to the thick, highly viscous lava that is produced by composite cone volcanoes.What is the difference between magma and lava?
What is the difference between magma and lava? Magma is composed of molten rock and is stored in the Earth's crust. Lava is magma that reaches the surface of our planet through a volcano vent.What are the six types of volcanoes?
Different types of volcanoes include stratovolcanoes, shield, fissure vents, spatter cones and calderas.What happens if you jump in lava?
So, generally, the nature of lava/magma makes it unlikely that you'll sink. You might burst into flames and burn when you hit the lava/magma's surface (depending on the type, lava's temperature ranges from approximately 1,200 to 2,200 degrees). You might also burn before you hit the lava/magma due to the radiant heat.What are the 7 types of volcanoes?
Geologists generally group volcanoes into four main kinds—cinder cones, composite volcanoes, shield volcanoes, and lava domes.- Cinder cones. Cinder cones are the simplest type of volcano.
- Composite volcanoes.
- Shield volcanoes.
- Lava domes.
