What are the types of volcanoes based on shape?
Different Types of Volcanoes
| Type of Volcano | Shape | Height |
|---|---|---|
| Cinder Cone, AKA Scoria Cone | Symmetrical cone | Up to 1,200 feet (370 meters) |
| Shield | Tall and broad | Up to over 30,000 feet (9,000 meters) |
| Composite, AKA Strato | Tall, steep, and symmetrical | Up to 8,000 feet (2,400 meters) |
| Lava Dome | Dome | Up to 330 feet (100 meters) |
What are the 2 shapes 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.
What type of volcanoes are dome shaped?
Lava domes are formed when erupting lava is too thick to flow and makes a steep-sided mound as the lava piles up near the volcanic vent.
What is the perfect shape volcano?
Mayon Volcano is renowned as the “Perfect Cone” because of its almost perfectly conical shape. Its sides are layers of lava and other volcanic material. Mayon is the most active of the active volcanoes in the Philippines, having erupted over 49 times in the past 400 years.
What are the four different shapes of volcanoes?
Geologists usually group volcanoes into four main types: cinder cones, composite volcanoes, shield volcanoes, and lava domes.
What are 3 types of volcanoes?
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 main shapes of volcanoes?
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.
Why are there different shaped volcanoes?
Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.
What type of volcano has a very broad shape with gentle slopes?
Shield volcanoes
Shield volcanoes are huge, gently sloping volcanoes built of very thin lava spreading out in all directions from a central vent. They have wide bases several miles in diameter with steeper middle slopes and a flatter summit. The gentle convex slopes give them an outline like a medieval knight’s shield.
What are 5 interesting about volcanoes?
Check out these 10 facts about volcanoes…
- Volcanoes are openings of the Earth’s surface.
- The word volcano comes from the word ‘vulcan’.
- Volcanoes can be active, dormant or extinct.
- The liquid inside the volcano is called magma.
- Lava is the liquid that is expelled from the volcano.
- Lava is very, very hot!

What are examples of volcanoes?
Some common examples of active volcanoes in the world are Mount Fuji I Japan, Kilauea in Hawaii, Santa Maria in Guatemala and Mount Etna in Italy. Dormant Volcanoes. There is a general confusion in understanding the difference between an active and a dormant volcano.
What are the types of volcanic eruptions?
There are seven types of volcanic eruptions: Strombolian, Vulcanian, Peléan, Hawaiian, Phreatic, Plinian, and subglacial. A Strombolian eruption, named after Stromboli in Sicily , consists of large blobs of magma thrown tens to hundreds of meters in the air, until they fall to the ground and produce short, viscous streams of lava.
