Essay about Volcanic Eruptions and Global Climate Change

One of the biggest tectonic events that has an effect on the earth climate is volcanic activity.

Assess the extent to which primary rather than secondary impacts are the more serious effects arising from volcanic eruptions. (30 marks)

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

Volcanos are beautiful yet discursive. They may have different effects on towns but some are similar, and some are different. Some may have an effect on both people and cities and the people's mindsets may change on their beloved homes.

Another physical factor is snow; if a volcano is snow capped, like Eyjafjallajokull, then the lahars and flash floods become a greater hazard. The flooding in Iceland in 2010 caused 700 people to be evacuated. Without the snow then lahars and floods may not be a problem at all.

Furthermore, acid magma is more likely to produce clouds of smoke and ash due to the explosive nature of the eruption it causes, than thinner, basic lava. Ash clouds, such as the one caused by the Icelandic volcano when it erupted in April 2010, which caused severe disruption to European air space, causing thousands of flights to be cancelled due to concerns over the hazards posed to air passengers travelling through the ash cloud.

The Earth has been experiencing a considerable amount of climate change for the last several decades. Natural factors that contribute to the climate system consist of: solar output, volcanic activity and earth’s orbit around the sun. The two factors relevant on timescales of contemporary climate exist in volcanic activity and changes in solar radiation. The earth’s energy balance primarily influences the amount of incoming energy from volcanic eruptions, which have a relatively short-term effect on climate. Changes in solar output have contributed greatly to climate trends over the past century. The effect of greenhouse gases in the atmosphere has been at least ten times that of changes in the Sun’s output and the ocean covers more than 70 percent of the earth’s surface, receiving twice the amount of earth’s radiation. Although the sun is the engine that drives all the weather, oceans and atmosphere control the sun 's energy along certain

How did the described volcanoes in Iceland and the Philippines change the environment to lesser or greater extents?

Volcanic eruptions not only give burning lava to the environment but the eruptions also release sulfur into the air (Mattox). This may sound familiar as coal burning power plants

The article primarily appeals to individuals with interest in global warming. The main point that Wood focuses on is the idea of sulfur-aerosol injection, in which sulfur dioxide would be pumped into the sky. However, there are several issues with this concept that he addresses in his article.

Volcanoes are in fact important because without volcanoes the atmosphere wouldn’t have its oxygen rich properties. Many of years ago, Earth’s atmosphere was swarm with rock-forming minerals of the earth 's crust. During earlier volcanic eruptions many gasses enters into the earth atmosphere. Carbon dioxide, water vapor and many other gases

Introduction: Since the beginning of time, volcanoes have been wreaking havoc on the world, as we know it. Yet in the more recent times, there has been a great amount of debate regarding the effect of volcanic eruptions on world climate change. In this report, the effects of these volcanoes will be explored, particularly in regards to cooling and the depletion of the ozone.

The main effect on weather right near a volcano is that there is often a lot of rain, lightning, and thunder during an active volcano that is eject lava, ash, and gases. This is because all the ash particles that are thrown up into the atmosphere are good at attracting/collecting water droplets. The particles moving through the air and separating positively and negatively charged particles.
