Short Essay on Volcanoes

Volcanoes are openings on the surface of the planet allowing hot lava, ash, and gas to escape from the bottom of the earth's surface.

The name "volcano" comes from the Vulcan Fire God of Roman mythology. Volcanoes are like huge safety valves, releasing the pressure generated inside the earth. The Hawaiian Islands are made up of 5 volcanoes

There are four kinds of volcanoes classified by activity level. An "active" volcano is a volcano that erupts often. There are about 500 active volcanoes on the earth except for the volcano at the bottom of the ocean.

"Dormant" Volcano is a volcano that has not erupted for many years, but there are still some activities in it. "An extinct" volcano is a volcano that is no longer active.

Volcanic eruptions occur when hot rocks and lava erupt from a volcano; the geysers and hot springs are actually just volcanoes. They are caused by groundwater trapped by the heat of the volcano.

The lava in the volcano is called magma and it is called lava when it flows out. The temperature of fresh lava ranges from 700 degrees Celsius to 1,200 degrees Celsius, and it generates hot incandescence when flowing. The most dangerous volcanic eruption recorded was the eruption of Mount St. Helens in Washington.

The highest volcano in the world is Ohos del Surardado, Chilean volcano. The largest volcano in the world is Hawaiian Muanro.

Volcanoes generally concentrate on the edge of the continent along the chain of islands or form long mountains on the ocean floor. The majority of the world's active volcanoes surround the Pacific Ocean and form a "circle of fire".

Volcanic eruptions can have a serious impact on the land and its surroundings. The damage left by them led to completely destroying the surrounding landscape. In the past 500 years, about 20,000 people died due to volcanic eruption.

The building is destroyed, people are homeless, people are killed, plants and animals are destroyed, and toxic gases released from the volcano can cause diseases such as death and pneumonia.

But everything related to volcanoes is not negative. The crust of the earth,

A large amount of magma did not erupt but cooled down below the surface. It makes fertile soil and contributes to cultivation.

The volcanic ash that erupts from the volcano increases the soil fertility by adding nutrients to the soil. Groundwater heated by magma can be used as geothermal energy. Most metal minerals such as copper, gold, silver, lead and zinc are extracted from the magma deep inside the extinct volcanic roots.

As scientists research more and more volcanoes, they can measure the level of volcanic activity. With this information, you may not be able to prevent volcanic eruptions, but at least large-scale human life damage can be avoided by evacuating personnel in time.

What I remember from my nephew's visit is to check Inside Out. In the first video, a solitary volcano formed an island with love until another volcano reacted and joined the first erupting volcano. In the theater, my wife and I keep hands and smile at each other and remind me of their island making. Then I noticed that my nephew was crying quietly and my mouth became narrow with pain - and she did not do anything to stop the tears on the other side of my wife.

What comes from a volcano * Lava * Tephra (rock fragments) * Why does the gas eject? When magma and natural gas find escape routes, the volcano erupts. Volcanic eruptions may be mild and / or violent. Active volcanic type * - often * inject a dormancy - a specific period, also known as sleep * do not erupt during extinction - erupted during a volcano of at least 100,000 years or more? The volcano is a volcano that is open on the surface of the planet or in the Earth's crust, allowing hot magma volcano to be a conical structure emitted by lava. The domed structure not only adds to natural beauty but it makes it more spectacular, and on the other hand they are very dangerous as it helps to bring about huge disasters. As an example, the word volcano originated from the name Balkan, which means Roman Balkan. The volcanic eruption was thought to be one century ago.
