Are Volcanic Eruptions Good For The Earth. Third point：volcanic eruptions can lower earth’s temperature if there are any huge fluctuations on the earth that threaten the survival of human beings? Many lives can be lost as a result of a volcanic eruption.

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.the internal heat associated with young volcanic systems has been harnessed to. They are found throughout the world, forming ridges deep below the sea surface and mountains that are thousands of meters high. Many lives can be lost as a result of a volcanic eruption.

They produce ash, lava, volcanic bombs, pyroclastic flows and lahars. Volcanoes erupt when molten rock called magma rises to the surface.

On longer time scales, eruptions can inject massive quantities of ash into the atmosphere, greatly reducing the solar heating of the earth and potentially interrupting the global food supply for several years. Many lives can be lost as a result of a volcanic eruption.

Volcanic deposits are also used as building materials. The lava and ash deposited during an eruption breaks down to provide valuable nutrients for the soil.

Even if mars never had conditions suitable for life on its surface, despite volcanic eruptions, life could have flourished beneath, nasa scientists suspect. They are found throughout the world, forming ridges deep below the sea surface and mountains that are thousands of meters high.

Volcanic eruptions are dramatic and violent events, and volcanoes are a great example of how small, incremental changes can lead to big transformations over long periods of time. The lava and ash deposited during an eruption breaks down to provide valuable nutrients for the soil.

Effects of volcanic eruptions e.g. Volcanoes have a large effect on their locality. How do volcanic eruptions affect society?

Volcanic Eruptions Are Dramatic And Violent Events, And Volcanoes Are A Great Example Of How Small, Incremental Changes Can Lead To Big Transformations Over Long Periods Of Time.

Large eruptions every year produces about 110 million ton (99790.3 million kg) of co2, while human activities produce billions of tons of co2. Major eruptions alter the earth's radiative balance because volcanic aerosol clouds absorb terrestrial radiation, and scatter a significant amount of the incoming solar radiation, an effect known as radiative forcing that can last from two to three years following a volcanic eruption. A volcanic eruption definitely adds carbon dioxide to the atmosphere but compare that to the amount of co2 created by human activities, and it isn't as big a threat.

Many Lives Can Be Lost As A Result Of A Volcanic Eruption.

Third point：volcanic eruptions can lower earth’s temperature if there are any huge fluctuations on the earth that threaten the survival of human beings? They helped cool off the earth removing heat from its interior. This creates very fertile soil.

Volcanoes Make Islands And Add To The Continents.

Global warming is undoubtedly the biggest concern for everyone. This creates very fertile soil which is good for growing fruit and vegetables. There are very few extinct, and thus safe, volcanoes on the earth.

Most Of Earth’s Atmosphere, Water, And Crust Were Delivered By Volcanoes, And Volcanoes Continue To Recycle Earth Materials.

Volcanoes have done wonderful things for the earth. More than a dozen are usually erupting at any time somewhere on earth, and close to 100 erupt in. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.
