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

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

The Three Classic Types of Volcanoes

• Cinder Cone Volcanoes.
• Composite Volcanoes (Stratovolcanoes)
• Shield Volcanoes.

What are the 4 classifications of volcanoes?

Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.

What is the tube in the middle of a volcano called?

Conduit – An underground passage magma travels through. Summit – Highest point; apex. Throat – Entrance of a volcano. The part of the conduit that ejects lava and volcanic ash.

Are composite volcano high or low silica?

Composite volcanoes have the following characteristics: Andesitic magma, which is lower in temperature, has more silica and a lot of dissolved gases and is more likely to explode when it reaches the surface. Acidic lava, which is very viscous (sticky).

What are the types of eruption?

Types of eruptions

• Hydrothermal eruption. An eruption driven by the heat in a hydrothermal systems.
• Phreatic eruption. An eruption driven by the heat from magma interacting with water.
• Phreatomagmatic eruption.
• Lava.
• Strombolian and Hawaiian eruptions.
• Vulcanian eruptions.
• Subplinian and Plinian eruptions.

What are the different types of eruption?

How many types of eruptions are there?

Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian. Encyclopædia Britannica, Inc.

What is the hole in the top of a volcano called?

The crater is the bowl shaped opening located at the top of the volcano.

What type of volcano has low silica content?

Shield Volcano
1) Shield Volcano: low silica content produces a fluid lava that flows out of a vent and builds up layer upon layer producing a “classic” volcanic cone shape. Shield cones are very tall with a broad base.

What type of eruption Do composite volcanoes have?

Composite volcanoes are built up by successive eruptions of domes, lava flows and pyroclastic flows, but also can experience large blasts that destroy large areas of their summits, such as the May 1980 explosion and landslide at Mount St. Helens. Landslides may occur during eruptions or at other times.

What type of volcano is the most explosive?

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.

Why is Crater Lake so blue?

Famous for its beautiful blue color, the lake’s water comes directly from snow or rain — there are no inlets from other water sources. This means no sediment or mineral deposits are carried into the lake, helping it maintain its rich color and making it one of the cleanest and clearest lakes in the world.

Is magma hotter than lava?

Magma is hotter than lava depending on how recently the lava reached the surface and if the magma and lava are from the same magma chamber below the…
