Is volcano good or bad?
Living with volcanoes is not all bad. Volcanoes provide a wealth of natural resources in the form of building materials, hot springs, freshwater and fertile soil. However, there are more hidden aspects, which was the focus of a recent collaboration with an archaeologist.
Can we live without volcano?
Without volcanoes, most of Earth’s water would still be trapped in the crust and mantle. Volcanoes may be devastating in the moment, but ultimately Earth’s life would not be the same, if it existed at all, without volcanoes.
What is a volcano one word answer?
The Short Answer: A volcano is an opening on the surface of a planet or moon that allows material warmer than its surroundings to escape from its interior. When this material escapes, it causes an eruption. Lava fountain at Kīlauea Volcano, Hawai`i. Credit: J.D Griggs, USGS.
Can you describe the volcano?
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. As the magma rises, pressure decreases, allowing the gases to form bubbles.
Why do people live near volcanoes?
People live close to volcanoes because Geothermal energy can be harnessed by using the steam from underground which has been heated by the Earth’s magma. Volcanoes attract millions of visitors around the world every year. Apart from the volcano itself, hot springs and geysers can also bring in the tourists.
How hot is lava?
The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt. Once that happens, the magma (molten rock) will rise toward the surface (it floats).
Did volcanoes create the Earth?
More than 80 percent of the Earth’s surface–above and below sea level–is of volcanic origin. Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth’s earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life.
Are volcanoes good for the Earth?
Volcanoes have done wonderful things for the Earth. They helped cool off the earth removing heat from its interior. Volcanic emissions have produced the atmosphere and the water of the oceans. Volcanoes make islands and add to the continents.

What is the 5 description of volcano?
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. Eruptions can cause lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. The danger area around a volcano covers about a 20-mile radius.
What is a volcano in your own words?
The word volcano is used to describe either a kind of mountain built up of volcanic rock or vent that pours out gas, molten rock and volcanic ash. Volcanoes are built by the accumulation of their own eruptive products: lava bombs, lava flows, pyroclastic flows and tephra.
