What is a volcanic cone for Class 7?
Answer: Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption.
What are the 3 volcanic cones?
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.
What type of volcano is spatter cones?
Spatter cones are one of the main types of volcanic type landforms. They are made from lava that was ejected from a vent. The spatter cones are easy to distinguish especially during eruption. Unlike some volcanoes that produce lava flow during eruption, the eruptions in spatter cones are similar to explosion.
Why are volcanoes cone shaped?
They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up. The result is a cone that has a gentler slope than a cinder cone but is steeper than a shield volcano.
What is volcano short answer?
A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth’s crust.
What do you think is the most attractive volcanic cone?
Mount Mayon, the Philippines Mayon is also a stratovolcano – a steep cone built from many layers of lava flows – that’s prized for its incredible symmetry. “The perfect hyperbolic shape of Mayon in the Philippines underlines [its] threatening posture,” Vortselas said.

What happens if you jump in lava?
The extreme heat would probably burn your lungs and cause your organs to fail. “The water in the body would probably boil to steam, all while the lava is melting the body from the outside in,” Damby says. (No worries, though, the volcanic gases would probably knock you unconscious.)
Which type of volcano is the most explosive?
Stratovolcanoes are considered the most violent. Mount St. Helens, in Washington state, is a stratovolcano that erupted on May 18, 1980.
What is the most perfect cone shaped volcano?
Mayon Volcano
Mayon Volcano, active volcano, southeastern Luzon, Philippines, dominating the city of Legaspi. Called the world’s most perfect volcanic cone because of the symmetry of its shape, it has a base 80 miles (130 km) in circumference and rises to 8,077 feet (2,462 metres) from the shores of Albay Gulf.

What are 5 interesting facts about volcanoes?
Top 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 is the volcano that has the perfect cone?
Mount Mayon, also known as the Mayon Volcano, is an active stratovolcano on the island of Luzon in the Philippines, renowned for its almost symmetric conical shape. Mayon is considered to have the world’s most perfectly formed cone due to its symmetry, which was formed through layers of pyroclastic and lava flows from past eruptions and erosion.
What are the kinds of cone volcanoes?
AKA Scoria Cone. One of the most common types of volcanoes is the cinder cone.
What determines the types of a volcanic cone?
Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Osorno volcano in Chile is an example of a well-developed stratocone.
What does secondary cone mean in a volcano?
Also known as a Parasitic Cone, secondary cones build up around secondary vents that reach the surface on larger volcanoes. As they deposit lava and ash on the exterior, they form a smaller cone, one that resembles a horn on the main cone.
