What is the most powerful type of volcano?
stratovolcanoesThe most well-known stratovolcanoes are Krakatoa, Mount Helen, and Vesuvius.
Another famous stratovolcano is Mount Tambora – the site of the most powerful eruption in recorded history.
Its volcanic cloud lowered global temperatures by as much as 3.5°C for up to one year..
What type of volcano has the greatest slope?
stratovolcanoesOf the different types of volcanoes, stratovolcanoes have the greatest slope.
What is the difference between magma and lava?
Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.
What are the 3 types of volcano?
Volcanoes are classified by the eruption type and by the volcanic cone shape. There are three basic cone shapes and six eruption types. The three cone shapes are cinder cones, shield cones, and composite cones or stratovolcanoes.
Is Taal a shield volcano?
There are actually three types of volcanoes namely shield, cinder and composite cones. The shield cone looks like an inverted semi-sphere. This type of volcano does not burst out violently. … One example of that is Taal Volcano, a small volcano located in an island at Batangas, Philippines.
Why is the stratovolcano the most dangerous?
Of all the volcanoes on Earth, stratovolcanoes are the most dangerous. They can erupt with little warning, releasing enormous amounts of material. … As we saw with Mount Saint Helens, they can blast out material from the side, creating pyroclastic flows the hurtle down the volcano’s flanks at enormous speeds.
What is the smallest type of volcano?
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Where are most volcanoes located?
Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
What is a steep sided volcano?
Cone volcanoes If you’re asked to picture a volcano, the steep-sided, cone-shaped volcano that immediately comes to mind is called a cone volcano. (It’s also sometimes called a stratovolcano or composite volcano.) Mt Taranaki and Mt Ruapehu are examples of cone volcanoes.
What are the 6 different types of volcanoes?
There are six types of volcanoes. They make up all the volcanoes on Earth. The six types are Cinder Cone Volcano, Stratovolcano, Shield Volcano, Rhyolite caldera complexes, Monogenetic fields, and Flood Basalts.
Do all volcanoes erupt lava?
Scientists realized long ago that no two volcanoes erupt the same. … Effusive eruptions – magma rises through the surface and flows out of the volcano as a viscous liquid called lava. Explosive eruptions – magma is torn apart as it rises and reaches the surface in pieces known as pyroclasts.

Which lava moves slowly?
Other lavas: Other types of lavas include block lava, which has a surface of large angular blocks, and rhyolite lava. These two types are associated with lava chemistries other than basalt. They tend to be very thick (10-200 meters) and slow moving.
Which volcanoes are more likely to explode thick lava or thin lava?
The lava that flows from both types of eruptions is very hot, thin, and runny which allows for fast flowing lava flows. The main difference lies in the fact that most Hawaiian eruptions have the greatest quantity of lava pouring out of the main vent at the volcano’s summit, not along side fissures.
How many volcano types are there?
When magma erupts at the surface it can form different types of volcanoes depending on the viscosity, or stickiness, of the magma, the amount of gas in the magma, and the way in which the magma reached the surface. Different types of volcanoes include stratovolcanoes, shield, fissure vents, spatter cones and calderas.
