Cinder cones are both the most common type of volcano and also the smallest. The cinder cone resembles a composite volcano but on a much smaller scale. They rarely reach even 300 meters in height but have even steeper sides than a composite volcano. They usually have a crater at the summit.
What is the smallest type of volcano?
Cinder cones are the smallest volcanoes and result from accumulation of many small fragments of ejected material. An explosive eruption may create a caldera, a large hole into which the mountain collapses.
What are the 4 types of volcanoes?
Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.
What is the simplest volcano?
Cinder Cone
Cinder cones are the simplest type of volcano. They are made of small pieces of solid lava, called cinder, that are erupted from a vent. The ground shakes as magmarises from within the Earth. Then, a powerful blast throws molten rocks, ash, and gas into the air.

What is the most powerful volcano on Earth?
Rising gradually to more than 4 km (2.5 mi) above sea level, Hawaii’s Mauna Loa is the largest active volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa’s great mass another 8 km (5 mi).
What is the safest type of volcano?
Shield Volcanoes
A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. They have very gentle slopes and are very developed horizontally. These are the classical Hawaii examples – steady flow and accumulation of lava leading to the shield-type formation.
What is the largest type of volcano?
The world’s largest volcano, Mauna Loa in Hawaii, is a shield volcano, according to the U.S. Geological Survey. Mauna Loa is about 55,770 feet (17,000 meters) from its base beneath the ocean to the summit, which is 13,681 feet (4,170 meters) above sea level.
What is a basic lava?
Lava: Magma that reaches the earth’s surface is called lava. It may be acidic or basic. Acidic lava is viscous, is lighter in colour and has higher silica content. Basic lava is non-viscous, is darker in colour and has lower silica content.

Can you fall into a volcano?
If you fall into a volcano, it’s magma that’s your problem. Most of us probably think of lava in the sense of lava flows, but you could also fall into a lava lake, which is lava that pools in a vent, crater or a depression on certain types of volcano.
Which volcanoes is the least explosive?
Shield volcanoes tend to be the least explosive volcanoes.
What’s 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 5 most active volcanoes in the Philippines?
The majority of the active volcanoes are located in the island of Luzon. The six most active volcanoes are Mayon, Hibok-Hibok, Pinatubo, Taal, Kanlaon and Bulusan.
How long does a volcanic eruption last?
According to the catalog “Volcanoes of the World” by Smithsonian Institution volcanologists Tom Simkin and Lee Siebert, 9 percent of eruptions end in less than one day, 16 percent within two days, 24 percent within one week, 30 percent within two weeks, 43 percent within a month, 53 percent within two months, 83 …
Why is Taal Volcano a complex volcano?
Taal is defined as a “complex volcano” – it doesn’t have just one main vent or cone but several eruption points that have changed over time. … Volcano Island alone has 47 craters and 4 maars – volcanic craters that form when hot magma comes into contact with shallow ground water, producing a violent steam explosion.
