What is a volcano question answer?

A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Volcanic eruptions are partly driven by pressure from dissolved gas, much as escaping gases force the cork out of a bottle of champagne.

What do I want to know about volcanoes?

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. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. More than 80% of the earth’s surface is volcanic in origin.

How do volcanoes erupt again?

Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth’s surface.

Can a dead volcano come back to life?

Volcanoes typically are categorized thusly: active (a volcano that has erupted in the past 10,000 years), erupting (an active volcano that is experiencing an eruption), dormant (an active volcano that has the potential to erupt again), and extinct (a volcano that has not erupted in over 10,000 years and is unlikely to …

Can you trigger a volcano?

There are many theories of what can trigger a volcano to erupt. Some are as simple as the buoyancy of magma — it is less dense than the surrounding rock, so it rises until it intersects the surface. This might be high levels of volcanic gases, shallow earthquakes, deformation of the volcano.

How overdue is Yellowstone eruption?

Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions.

What are the 7 types of volcano?

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 is the most dangerous type of eruption?

Composite volcanoes are some of the most dangerous volcanoes on the planet. They tend to occur along oceanic-to-oceanic or oceanic-to-continental boundaries because of subduction zones. They tend to be made of felsic to intermediate rock and the viscosity of the lava means that eruptions tend to be explosive.

Is Mount Everest a volcano?

Formed from clashing of two tectonic plates – the Indo-Australian and Eurasian plates, Mount Everest is not a volcano. Mount Everest is a mountain.

Is Mt Everest still growing?

Growth of Everest The Himalayan mountain range and the Tibetan plateau were formed as the Indian tectonic plate collided into the Eurasian plate about 50 million years ago. The process continues even today, which causes the height of the mountain range to rise a tiny amount every year.

Can you live on Mount Everest?

Humans can survive at high altitudes. Yet still about one out of every five of them gets symptoms of altitude sickness that are severe enough to interfere with their activities. Mount Everest is the highest place on Earth. It rises an unbelievable 29,035 feet (8850 m) above sea level.

What animals live on Mt Everest?

Everest Region and its wildlife Some of the wild animals of the Everest region include Snow Leopard, Himalayan Tahrs, Red Panda, Musk Deer, and Wild Yak. Snow Leopard and the Red Panda are among the rare and endangered species of the country. There are only about 500 Snow Leopards remaining in the Himalayas of Nepal.

What happens to the bodies on Mt Everest?

In the death zone, climbers’ brains and lungs are starved for oxygen, their risk of heart attack and stroke is increased, and their judgment quickly becomes impaired. “Your body is breaking down and essentially dying,” Shaunna Burke, a climber who summited Everest in 2005, told Business Insider.
