There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.
What are the 3 classification of Volcano?
Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again.

What are the 3 types of volcanoes describe the differences between each type?
There are three main types of volcano – composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. … When composite volcanoes erupt they are explosive and pose a threat to nearby life and property.
What are the four types of volcanoes?
Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.
What is the 2nd biggest volcano in the world?
- Pūhāhonu – The second-largest volcano known on earth, recently discovered to be nearly twice as large as Mauna Loa.
- Mauna Loa – The third-largest volcano known on Earth; also the largest known volcano extending above sea level.
- Ring of Fire.
What is the smallest volcano?
We usually think of volcanoes as huge formations in inaccessible areas, but we want to tell you about one that breaks this stereotype. The Cuexcomate is known as “the smallest volcano in the world” and it is located just 15 minutes away from downtown Puebla in central Mexico.

What are the 6 different types of volcanoes?
Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.
What are the two primary types of volcanoes?
Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes.
Can lava burn in water?
So no, lava cannot burn underwater. It will lose heat very quickly and turn into basalt, pumice, obsidian, igneous or a combination of various rocks when cooled but no burning.
Are there volcanoes underground?
From Hawaii to Indonesia to Iceland, hundreds of islands across the globe have been formed by submarine volcanoes. Submarine volcanoes are exactly what they sound like—volcanoes located beneath the ocean’s surface.
What is the most powerful volcano on Earth?
Tambora – Indonesia – 1815 The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.
What is the oldest volcano?
The oldest volcano is probably Etna and that is about 350,000 years old. Most of the active volcanoes that we know about seem to be less than 100,000 years old. Volcanoes grow because lava or ash accumulates on the volcano, adding layers and height.
How hot is lava?
The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt. Once that happens, the magma (molten rock) will rise toward the surface (it floats).
What is the youngest volcano in the world?

Is Kilimanjaro a volcano?
Kilimanjaro has three volcanic cones, Mawenzi, Shira and Kibo. Mawenzi and Shira are extinct but Kibo, the highest peak, is dormant and could erupt again. The most recent activity was about 200 years ago; the last major eruption was 360,000 years ago. 8.
Can you go inside an extinct volcano?
It’s only possible to descend in to Thrihnukagigur on the Inside the Volcano tour because of safety and security reasons. You can either be picked up at your hotel in Reykjavik, or you can opt to arrive at the mountain hut in the Bláfjöll Nature Reserve on your own though.
Can a plane fly over Everest?
Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.
Where are the three places that volcanoes form?
- Hot spots,
- Divergent plate boundaries (such as rifts and mid-ocean ridges), and.
- Convergent plate boundaries (subduction zones)
What are the different types of volcanoes according to shape?

How does lava taste like?
Some will have a touch of sulfur, others will have clay like flavors if weathered. Freshly cooled lava can have smell and taste from roasted trees and other organics that it burned up. Consider that Hawaiian lava cooled in the ocean might taste salty unless the salt was washed away with rain water.
Why is lava red?
Simply put, because it’s hot – in fact, lava can reach up to 1,250 degrees Celsius (2,282 degrees Fahrenheit). Heat excites atoms, which can boost atoms’ electrons to higher orbitals. When an excited electron returns to its normal orbital, it releases its excess energy as a light photon.
Can lava melt diamond?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.
