What are the results of volcanoes?
Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. … Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
What is the best describes the volcano?
A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time.
What is the importance of studying volcano?It is important to know about volcanoes because volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive and it can kill you. We should care because if a volcano erupts around where we live, we would know how to protect ourselves from it.
What is your conclusion regarding the location of volcanoes earthquake and mountain ranges?
Volcanoes, earthquakes, and mountain ranges can all be found at the site of convergent boundaries. Finally, earthquakes are also found at the site of transform boundaries. Each of our learning activities was a line of evidence.
What is the impact of volcanoes on the environment?
Further effects are the deterioration of water quality, fewer periods of rain, crop damages, and the destruction of vegetation. During volcanic eruptions and their immediate aftermath, increased respiratory system morbidity has been observed as well as mortality among those affected by volcanic eruptions.
What are volcanoes Wikipedia?
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.
What are the positive and negative effects of volcanic eruption?Positive: Lava and Ash deposited during an eruption breaks down to provide valuable nutrients for the soil… this creates very fertile soil which is good for agriculture. Negative: Deadly and devastating Lahars are made when… ash and mud from an eruption mixes with rain or melting snow making fast moving mud flows.
How volcanic eruption effects the society?
Lava flows and lahars can wipe out the flanks of mountainsides. Volcanic ash can blanket the landscape for miles, and ash clouds can disrupt aircraft travel, such as the incident in 1989 when ash from Alaska’s Redoubt volcano temporarily disabled a passenger airplane.What did you learn about 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. 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.Article first time published on askingthelot.com/what-is-the-conclusion-of-volcanoes/
What is a volcano in your own words?
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.
How do you describe a volcano?
What is a volcano? Volcanoes are openings, or vents where lava, tephra (small rocks), and steam erupt on to the Earth’s surface. Many mountains form by folding, faulting, uplift, and erosion of the Earth’s crust. Volcanic terrain, however, is built by the slow accumulation of erupted lava.
What can you conclude on the relationship between volcanoes and earthquakes?
Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock. Then the magma squirts into the crack and starts building pressure again. Every time the rock cracks it makes a small earthquake.
How do earthquakes and volcanoes affect human life?
Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields.
Why do you think earthquakes and volcanoes occur in these areas?
Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. At diverging plate boundaries, earthquakes occur as the plates pull away from each other. … We almost never see these volcanoes, because most of them are located on the sea floor.
How can we protect against volcanoes?
- Stay inside, if possible, with windows and doors closed.
- Wear long-sleeved shirts and long pants.
- Use goggles to protect your eyes. …
- Exposure to ash can harm your health, particularly the respiratory (breathing) tract. …
- Keep your car or truck engine switched off.
What is meant by volcano eruption?
A volcanic eruption is when lava and gas are released from a volcano—sometimes explosively. The most dangerous type of eruption is called a ‘glowing avalanche’ which is when freshly erupted magma flows down the sides of a volcano.
Why are volcanoes called Mount?
Because volcanoes are mountains. In fact many active volcanoes are referred to as “mountain” in their name. Mount Vesuvius, Mount Etna, Mount Erebus .. the list goes on. In some cases we use the native language equivalent for mountain : Mauna Loa, Mauna Kea, etc.
What are several positive ways that volcanoes can affect humans?
- volcanic rock and ash provide fertile land which results in a higher crop yield for farmers.
- tourists are attracted to the volcano, which increases money to the local economy.
- geothermal energy can be harnessed, which provides free electricity for locals.
Why is it important to know about the effects of volcanic eruptions?
Volcanic eruptions are one of Earth’s most dramatic and violent agents of change. … The warning time preceding volcanic events typically allows sufficient time for affected communities to implement response plans and mitigation measures. Learn more: Comprehensive monitoring provides timely warnings of volcano reawakening.
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 do volcanoes affect the economy?
The most common consequences of volcanic events include loss of life, respiratory illness, and severe economic losses, including destruction or damage to housing, infrastructure, and land.
How does volcanic activity affect the environment advantages and disadvantages?
Advantages – Precious minerals; geothermal energy; fertile soil; tourism (jobs); beauty products; souvenirs. Disadvantages – Destruction during eruptions; magma/ash destroys everything; earthquakes; pollution; sea life; quarries.
Are volcanoes good or bad?
Volcanoes are dangerous. They can kill people and damage property. Economic activity can suffer as it is hard for businesses to operate after an eruption. Habitats and landscapes are damaged by lava flows.
Do volcanoes have positive effects?
There are many positive effects of volcanoes including: Fertile soils, tourism, geothermal energy, creation of new land and building materials. Volcanic soils are very fertile. These rich soils are called laterite soils and are rich in minerals.
How do people learn about volcanoes?
Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is …
What are some important 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 very, very hot!
What is volcano Class 7 short?
An opening in the earth’s crust that allows hot molten lava, ash and gases to escape from below the surface, is called a volcano.
Why do volcanoes form?
On land, volcanoes form when one tectonic plate moves under another. Usually a thin, heavy oceanic plate subducts, or moves under, a thicker continental plate. … When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
Are volcanoes real?
There are volcanoes on every continent, even Antarctica. Some 1,500 volcanoes are still considered potentially active around the world today; 161 of those—over 10 percent—sit within the boundaries of the United States. But each volcano is different.
How are volcanoes formed lesson for kids?
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. … Hot ash and gases are thrown into the air. Some volcanoes are covered with snow and ice. If they erupt, melted snow and ice mixes with mud and volcanic ash and flows down mountain.
