This volcanic ash and rain combine to form and cause flooding that can wash away roads, bridges, and can even flood nearby villages and cities, leaving many people homeless and destroying everything in its path. The ash produced by volcanoes is very light, which means that it can cover a large area and be absorbed quickly. Lets delve deeper into the topic to seek more clarification. Firstly and most commonly,the advanced technology make the people more lethargic. The ash clouds produced by volcanoes can also interfere with aviation.

This could cause serious health issues for people only with heart or respiratory problems. Volcanoes erupt when magma reaches the surface due to high pressure and starts to pool in a magma chamber. A secondary problem is lahars and mudflows produced in rivers and lakes. Besides, tourists also enjoy the steam vents, mud pools, hot springs, and bathing lakes that are usually found around an area with considerable volcanic activity. The slow flow of highly viscous lava from a Hawaiian eruption creates a large, low-profile volcano that resembles a circular shield.

However, the other two major types of volcanoes -- cinder cones and stratovolcanoes -- feature eruptions that are much more violent than those of shield volcanoes. This is because there needs to bemillions of tons of sulfate ejected into the stratosphere mostlyfrom tropical volcanoes , which then makes its way around theglobe, effectively blocking the sun. Those without an eruption are often triggered eathquakes, by weakening of rock into clay by hydrothermal activity, or by heavy rainfall or snowfall. It was a slow process and it had happened for billions of years. When lava and ash cool and settle after an eruption they decompose and release valuable nutrients into the soil. The engines are thought to have shut down because the ash turned to a glass coating, which fooled the temperature sensors and esulted in an auto-shutdown.

Once the volcano erupts the magma is called lava. Earth layers are Inner Core, Outer Core, Mantle, and Crust. However, Shield volcanoes are named due to their shape. It was like an egg being boiled until it finally cracked, but in this case it would not be the soft yellow centre squirting out, it would be a vast flow. In this article, we will discuss one of the most interesting things on the earth i. That warmer material inside the surface is called Magma.

Volcanic eruptions throughout history have been known to cause mass destruction from lahars. Mostly children dependent on computers for multifarious purposes. In the months that followed over 200 lahars occurred and destroyed road, towns, crops and bridges. Several eruptions during the past century have caused a decline in the average temperature at the Earth's surface of up to half a degree Fahrenheit scale for periods of one to three years - sulfur dioxide from the eruption of Huaynaputina probably caused the Russian famine of 1601 - 1603. This volcanic ash is very dense and creates unbreathable air.

Discovering new talents- It is always a refreshing to see a new and creative designer come into the spotlight. Aso viewed from the visitors center. In terms of effects volcanoes have both positive and negative effects but the first sort of classification is that of primary and secondary effects. The eruptions materials released by volcano can be useful. So it is better to evacuate places if such place is near to the volcano which can cause pyroclastic flows.

To ancient Greeks Mount Etna is known as the God of fire. It should also be pointed out that it is not feasible to either accurately predict or even prevent a volcano from erupting since we lack the requisite technology. I guess the main good effect that volcanoes have on the environment is to provide nutrients to the surrounding soil. A volcanic eruption occurs when hot rocks and lava burst from a volcano. This is why we need to take a closer look at some of the positive and negative effects of volcanic eruptions.

Consequently, they got considerable material losses, which burdening the victim. Volcanic ash A volcanic eruption is always accompanied by huge amounts of volcanic ash, which is often extremely thick and capable of enveloping the sky and pervading the air for days on end. This ash cloud circled the earth and decreased global temperatures by about one degrees over the next year. Here are 10 positives of the fashion industry. What we are experiencing now has been referred to as the Great Recession of 2007-2010.

Inspiration- Fashion inspires others to be creative and to want to build a career from it. The earth is made up of huge plates, these plates shift gradually over a time period of millions of years. They helped cool off the earth removing heat from its interior. Cinder cone volcanoes are cone craters which are usually small and steep shaped made up of lots of little rock or cinders filled with gas shooting straight up into the air and cooling rapidly thereby falling back close to the source. Their height greatly increases the residence time of these fine particles in the atmosphere—they are not washed quickly back to Earth but spread slowly into haze layers that can blanket a hemisphere or even the entire Earth. Lahars: Volcanic ash which when mixed with water or snow also tends to create large mud slides known as lahars.
