INTRODUCTION Have you ever wondered what a volcano was ? Well, a volcano is a long tube that 's filled with lave. Also, lava is very hot and can burn you alive. What are volcanoes ? Volcanoes are openings in the surface of the earth from which gas or cold melton, or liquid, rock escape and cover the land with smoking hot lava.
This type of eruption is driven by thermal contraction where the temperature difference between the two results in violent water-lava interactions. The eruption usually has bursts of tremors, geothermal activity, mushroom cloud formation, and a large amount of ash. These tremors can result in earthquakes and geothermal activity refers to the melting of the ice. When the volcano erupts, a mushroom cloud can be formed from 30 km wide and 15 km high. In addition, ash is formed by the magma and glacial ice.
Tidal waves can likewise be created by submerged volcanic ejections. Volcanic emissions are another catastrophic event, and they are brought on by magma getting away from inside the earth. A blast happens, discharging the magma from a bound space, which is the reason there are frequently likewise gigantic amounts of gas and tidy discharged amid a volcanic emission. The magma goes up within the well of lava, and spills out over the encompassing territory as
1.1 Research Background Jet fires occur following the ignition and combustion of flammable fluids issuing continuously from a vessel, pipe or orifice, which burn close to the release plane. Jet fires dissipate thermal radiation away from the flame’s visible boundaries. The energy transmitted could be hazardous to both life and property. The pressure of release generates a long flame, which is stable under most conditions. A flash flame may take the form of jet flame on reaching the spill point.
Underneath the earth are plate tectonics, and when the earth drifts apart the plate tectonics move and cause many things to happen. Many of our landforms were created because of this. Three examples are volcanos, earthquakes, and mountains. To begin, volcanos are a great example of landforms being created by the movement of plate tectonics. When the plate tectonics move, it causes pressure inside the earth that creates volcanoes.
I choose this one because this explains how deadly this volcano was and is and what it could do if this happened again. "Then more terror. As the volcano loses energy, the molten rock and ash mix together to create a super heated wave that rushes down the mountain at 80 miles an hour. This burning avalanche is known as a pyroclastic flow.
Oxygen is affected by the fuel arrangement and feeds the process of combustion. When the fuel is gone, when the pilot heat source is not available, if there not enough heat, if ash builds up, or if the oxygen is limited then a leg of the triangle is broken and the fire goes out.

Commercial logging will affect the climate through the release of carbon from the vehicles and machines used to bring down trees. Fire used to clear lands releases carbon from the combustion process. Fire in the rainforest will generate a huge amount of carbon dioxide and huge volume of smoke causing the temperature to increase and expose humans to polluted smoke such as haze (Gorte.RW, 2010). This shows that carbon is released from every single process in the deforestation phase. As a conclusion, deforestation does indeed cause the temperature of the Earth to rise due to the heat from the burning and also carbon dioxide which will increase the greenhouse gases rapidly.
There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.
