What is a volcano short answer?
A volcano is an opening in a planet or moon’s crust through which molten rock, hot gases, and other materials erupt. Volcanoes often form a hill or mountain as layers of rock and ash build up from repeated eruptions. Volcanoes are classified as active, dormant, or extinct.
What are the causes of volcanic eruption?
Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.
What is an example of a dormant volcano?
Dormant → Dormant volcanoes are volcanoes that have not erupted in a long time but are expected to erupt again in the future. Examples of dormant volcanoes are Mount Kilimanjaro, Tanzania, Africa and Mount Fuji in Japan. Extinct → Extinct volcanoes are those which have not erupted in human history.
What is the strongest volcano in the Philippines?
The highest explosivity index in the Philippines was reached in the review period at VEI 6 in 1991. The volcano Pinatubo threw tephramasses of at least 10 cubic kilometers over 25 kilometers high. Such an intensity is normally only achieved every 100 years.
What are volcanoes made of?
They are made of small pieces of solid lava, called cinder, that are erupted from a vent. The ground shakes as magma rises from within the Earth. Then, a powerful blast throws molten rocks, ash, and gas into the air.
What are effects of volcanoes?
Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. People have died from volcanic blasts. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
How volcanoes are formed?
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
What are the 5 most dormant volcanoes?
Here are five that are sleeping, but could erupt again in your lifetime, so watch out.
- Mount Kilimanjaro. Three giraffe with Mount Kilimanjaro in the background at the National park of Kenya, Africa.
- Mount Fuji. Mountain Fuji and Chureito red pagoda with cherry blossoms.
- Mount Rainier.
- Mauna Kea.
- Three Sisters.
Where is the world’s largest dormant volcano?
The largest dormant volcano in the world, Haleakalā, makes up a large part of Maui. Mount Haleakalā is also called the East Maui Volcano. Haleakalā is considered a dormant volcano because it has not erupted in a long time, but it could erupt again in the future.
Why are volcanoes important?
Over geologic time, volcanic eruptions and related processes have directly and indirectly benefited mankind: Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations.
