being neutral‚ and zero being most acidic. The pH of acid rain is in the range of four point two to four point four. Humans are not the only specimens causing acid rain‚ volcanos and decaying vegetation contributes to the formation of acid rain. Volcanoes cause acid rain because the gas bubbles build up in the molten rock

Climate Pandemonium In late 2003‚ San Diego County was hit by a catastrophic firestorm created by several different large fires that formed together raging throughout the southern part of the state. The fires were fueled by the hot air of the Santa Ana winds; generating a towering wall of flames. Consequently‚ when firestorms roll through our neighborhoods it destroys everything in its path. The Road‚ a novel by Cormac McCarthy‚ shows the dramatic evidence of powerful forces at work with the eruption

The Impact of Hurricane‚ Earthquake and volcanoes on named Caribbean territories. The Caribbean territories are at the mercy of hurricanes‚ earthquakes and volcanoes. The region have a history of devastating geographical phenomena such as hurricane Gilbert in 1988 which kill 45 persons in Jamaica‚ 30 in Haiti and 5 in the Dominican republic‚ but the most devastating period for any one country in territories was in 2008‚ where in a three week span Haiti was hit by tropical storm Fay‚ hurricane

Why are some volcanoes more hazardous than others? There are several reasons that influence volcanic hazards‚ these include the viscosity of the magma‚ proximity to population centres‚ materials that are ejected from the volcano‚ the magnitude of the eruption and the plate margin that the volcano rests upon. The viscosity of the magma depends on 3 things‚ the temperature‚ dissolved gasses and the chemistry involved in the magma. These factors produce 2 main types of magma called acid and basic

This reduces the scientists’ credibility in the eyes of government and local people‚ and can cause problems the next time an eruption seems likely. 7. Prediction‚ forecasts and reactions - Active volcanoes all over the world are monitored using a vast array of scientific equipment. Satellites look for infrared radiation that indicates rising magma and ground instruments measure gas emissions‚ ground deformation and resulting earthquake activity. - Geologists use evidence from past eruptions

Volcanoes are big erupting mounting that shoot out hot lava/magma. Volcano eruptions produce a lot of toxic gases which can damage the environment. When a volcano is about to erupt there is rain‚ thunder‚ and lightning. Volcanoes can also be bigger or smaller than a mountain. There are many different types of volcanoes that cause destruction throughout the entire world. Volcanoes occur all over the world anytime of the day. Volcanoes occur at the mid-ocean ridges because they are divergent plate

Why people choose to live near volcanoes There are a number of different reasons why people choose to live near Volcanoes but here are just 5 of them: Cost of Moving The first and most important reason is that it is expensive to move away from volcanoes. There are people who cannot afford to move away and most of them are in denial and hope that these volcanoes nearby them will not erupt again. After all‚ when a volcano has long been dormant‚ it is easy to assume and hope that it will not erupt

the crater never gets plugged. This is the calculated risk that people take in order to live productive farming lives on the sides of volcanoes. The other main factor that is the cause for people living so close to volcanoes is geothermal energy. Heat from the earth’s crust is being converted into heat energy. In very cold countries with a high number of volcanoes this can therefore be very useful. For example in Iceland this method is used. The volcano Eldfield‚ Haemaey here has created many positive

killing thousands of people. The word volcano comes from the term Vulcan‚ which was a name the ancient Romans gave their god of fire. Volcanoes played a role in the religious life of some of these people‚ and they believed that god lived beneath a volcanic island off the Italian coast. Powerful forces within in the earth ’s surface cause the formation of volcanoes. Volcanoes begin as magma‚ deep inside the earth‚ which is caused by the extreme heat within the earth ’s interior. Magma develops from 15

Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) Your main factors can be put into two simple categories. Human and physical. From there you can then further explore the factors. In my essay I will mainly focus on viscosity‚ location‚ settlement and perception and explore how the physical and human factors intertwine with each other through one simple idea that physical factors dictate the hazard while human factors exacerbate the hazard.
