Volcanoes generally preserved geologic rock record eroded . However, materials erupted volcanoes found preserved rock record. From learned types volcanoes, infer type volcano erupted an area-based type volcanic deposits found layers rock? Give specific examples, briefly discuss materials linked types volcanoes. Volcanoes are some of the most interesting and at the same time intriguing manifestations of nature. They have been the object of study for decades and all types of technologies

Volcanoes are often associated with fire, earthquakes, victims and damage. The activity of nature often turns peaceful mountains with smoky tops into fire vents with lava and smoke getting out and turning everything into fire and burning it. Why do volcanoes erupt and where does such an incredible energy get from inside the earth? After the radioactivity phenomenon was discovered, especially one of uranium and thorium, scientists began to understand that the

S., with an estimated magnitude of 8.0 on the Richter scale. They formed new lakes, changed the course of the Mississippi River, and could be felt at least a little in a 50,000 square mile area. In contract, the San Francisco 1906 earthquake could be felt moderately in a 60,000 square mile area, even though it was a smaller quake. Kobe earthquake - Occurred in 1995 and measured 7.3 on the

Igneous rock is one of the three main types of rock formations making up the earth's crust. It is formed primarily through the cooling and subsequent solidification of magma or lava. Igneous rock may also form without any crystallization -- below the surface as intrusive rocks or above as extrusive. It is best to think of igneous rock as being formed with heat -- one or more of three processes:

Air pollution remains one of the most urgent and serious problems facing the world today. Research studies conducted in the past have clearly indicated that in addition to harming the environment, the effects of air pollution on human health are particularly adverse. In this text, I discuss air pollution, its causes, and effects. Further, I propose solutions that could be embraced to rein in the problem of air pollution. Air Pollution:
