A Volcano With Rugged Steep Sides

Why are the slopes of mt.

A volcano with rugged steep sides. Also called a stratovolcano. Having an irregular or jagged surface. Shield volcanoes get their name from their shape a huge shield laid on its side. Composite volcano a volcano with a broad base steep sides and often a crater at the top.

Supervolcano a massive volcanic eruption that is rare but incredibly powerful. You can see that shield volcanoes do not have the steep mountainous sides of composite volcanoes. How would you describe the topography around the crater of this volcano. Volcanic dome also called lava dome any steep sided mound that is formed when lava reaching the earth s surface is so viscous that it cannot flow away readily and accumulates around the vent.

A volcanic cone is the hill shaped landform that forms around a volcano. The volcano is composed of alternating layers of ash and lava flows. Figure 8 23 shows the mauna loa volcano. Sometimes domes are produced by repeated outpourings of short flows from a summit vent and occasionally extremely viscous lava is pushed up from the vent like a short protrusion of toothpaste from.

St helens and kilauea so different. How is the temperature of the lava related to the slope of the sides of a volcano. They have a very wide base and are much flatter on the top than composite volcano. Is it rugged steep valleys or gentle fairly flat.

How does the type of lava influence the slope. Most geologists classify a mountain as a landform that rises at least 1 000 feet 300. They usually have steep sloping sides and sharp or rounded ridges and a high point called a peak or summit.
