What are the Different Types of Volcanoes?
- Cinder Cone Volcanoes: These are the simplest type of volcano.
- Composite Volcanoes: Composite volcanoes, or stratovolcanoes make up some of the world’s most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi, for example.
- Shield Volcanoes:
- Lava Domes:
What are the 3 parts of Volcano?
The three main parts of a volcano are the chamber, the vent, and the crater. The chamber is where the magma is stored.
What is top of volcano called?
At the top of the volcano, at its highest point, is a crater. Some volcanoes have something called a caldera. A caldera forms when a volcano gets hollow and then collapses on itself.
What is main vent?
main vent – this is the channel through which magma travels to reach the Earth’s surface. secondary vent – some magma may escape through the side of the volcano, particularly if the main vent becomes blocked. crater – this is found at the top of the volcano, where the magma erupts from.
What is a volcano for Grade 3?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments.
What is the smallest volcano?
Can volcanoes kill you?
Most people killed by volcanoes are the victims of pyroclastic flows and lahars – volcanic mudflows, packed with debris – which have been responsible for about 120,000 deaths over the last 500 years. Pyroclastic flows are very fast avalanches of rock, ash and gas, which can reach temperatures of 700C.
What kills you in a volcanic eruption?
Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes. They are so hot and choking that if you are caught in one it will kill you.
Can you die from volcanic ash?
Carbon dioxide and fluorine, gases that can be toxic to humans, can collect in volcanic ash. If inhaled, volcanic ash can cause breathing problems and damage the lungs. Inhaling large amounts of ash and volcanic gases can cause a person to suffocate. Suffocation is the most common cause of death from a volcano.
