What are the 3 types of volcano according to its eruptive history?

There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes.

What type of volcano is Strombolian eruption?

In volcanology, a Strombolian eruption is a type of volcanic eruption with relatively mild blasts, having a Volcanic Explosivity Index of about 1 to 2. Strombolian eruptions consist of ejection of incandescent cinders, lapilli, and lava bombs, to altitudes of tens to a few hundreds of metres.

Which type of volcano is more eruptive?

stratovolcanoes
Because they form in a system of underground conduits, stratovolcanoes may blow out the sides of the cone as well as the summit crater. Stratovolcanoes are considered the most violent.

Which component of magma is the highest and lowest in value?

Felsic magma has the highest silica content of all magma types, between 65-70%. As a result, felsic magma also has the highest gas content and viscosity, and lowest mean temperatures, between 650o and 800o Celsius (1202o and 1472o Fahrenheit).

Which type of magma is most explosive?

Explosive eruptions are favored by high gas content & high viscosity magmas (andesitic to rhyolitic magmas). The explosive bursting of bubbles fragments the magma into clots of liquid that cool as they fall through the air.

What type of eruptions does a shield volcano have?

Although the type of eruptions found in a shield volcano can vary, most experience effusive eruptions. Effusive eruptions are the calmest types of volcanic eruptions and are characterized by the steady production and flow of basaltic lava that eventually builds up the shape of shield volcanoes.

What are the characteristics of a shield volcano eruption?

very low on silica and with low gas content.)

  • The lava erupted from the shield volcanoes are runny and non-acidic.
  • this results in the gentle sides of shield volcanoes.

    • What are facts about shield volcano?

    Shield Volcano Facts. A shield volcano resembles the appearance of a Hawaiian warrior’s shield in that they have a low-angle profile. In almost all cases the comparison to a shield is done because the width of these volcanoes is typically around 20 times the size of their height.
