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.

Analyse the factors that causes differences in the hazards posed by volcanoes around the world (40 marks)

A human factor that would cause differences in the hazards posed by volcanoes is settlement, which includes where people chose to live in relation to a volcano. For example, in Indonesia many people settle near Mount Merapi because of the rich and fertile soil favoured for farming. As Indonesia is a poor country many people rely on subsistence farming, therefore are willing to risk everything by settling beside a volcano. Furthermore, in the last eruption in 2010 360,000 people were displaced from their homes, meaning not only did they lose their home but also their livelihood; hundreds also lost their lives. Therefore, the hazards posed could have been minimalised if people chose to settle elsewhere.

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

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

In the article “The volcano-climate connection” by Jack Williams the author states “Scientists now know that these volcanoes, especially Tambora- the largest volcanic eruption of the last 10000 years- had spewed large amounts of sulfur dioxide into the air, which combined with water vapor to create a sulfuric acid mist of tiny particles that blocked up to 1or 2 percent of the solar energy that normally reaches the earth for months following the eruption.” The sulfuric acid mix that entered the air reflected some of the sunlight back into the atmosphere which caused unusually low temperatures in some parts of the world. The change in global weather patterns also had a large effect on agriculture causing

Volcanic eruptions happen all across the surface of the globe, many argue that if controlled and monitored they would have little effect on the population. However others argue that some volcanic events are too powerful or unpredictable to control.

Did you know that volcanoes don’t just destroy things but they can also help improve them? Volcanoes have a very strong impact on environments and people. They help environments by adding nutrients and making the soil very rich. Volcanoes affect people by helping their crops grow and farms succeed.

How will the rise in warmer temperatures and other atmospheric changes affect volcanoes and their sensitivity to erupting? How much more significant will the effects of these eruptions be in the future?

As human beings, we need to respect the environment in which we live. This is important to greater our future and that of others to follow. Very few people realize that their daily behaviors have a direct impact on the environment, the atmosphere in particular. By emitting harmful gasses into the air on a daily basis is one of the main reasons of such climate changes. People notice such changes and yet don't do anything to help the situation. Wee don't realize the risks that such changes in temperature pose. Rather than trying to conserve gas or taking cold showers, we still go on through our daily activities reluctant to change that will in time benefit the earth. By conserving gas

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.

How volcanoes affect people and environments? A volcano is a mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are in. Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.
