Solar energy is the main energy source sustaining life on planet earth and extending its usefulness to fulfill human needs is one of the research priorities around the world. Use of solar power as an alternative energy source have been studied for many decades and...
Solution for the energy crisis: Solar power
By: Bruce Lee1
People always ask, "how is solar power the solution behind our energy crisis?" The response is rather simple. With the sun’s natural light, we can produce more than 50 percent of the energy used on a daily basis by businesses, consumers, and even...
Do Synthetic Fabrics Harm the Environment
By: Glen Reese
All human activities impact the environment, especially those activities that consume fossil fuels and water - both of which are coming under increasing pressures. A better question is “Does the production and usage of synthetic fabrics have more negative impact than the available alternatives...

Pyroclastic flows are the mixture of solid to semi-solid fragments and gases that flow down the sides of a volcano. They are in a fluidized form. They are heavier than air emulsions (suspension of a liquid in another liquid). When they are falling, they look...

The magma (molten rock) found in volcanoes contains dissolved gases. Magma deep beneath the earth's crust is under tremendous pressures. As the magma rises towards the surface there is a decrease in the pressure that the magma is under, and the gases will come out...
How earthquakes may be connected to volcanic eruptions
By: Rex Trulove
Volcanoes and earthquakes go hand in hand, however they can exist for different reasons. It is worthwhile to look at the connection between the two. Volcano caused earthquakes Normally, before a volcano erupts, it produces a magma pocket of super heated and fluid rock beneath...

Listening to Obama and other alternative energy activists around the world, people might think that wind power represents the hope of a clean planet; free from the corrupting effects of oil and coal, but a report published by the U.K. Daily Mail paints an...

Vesuvius, the only active volcano on mainland, has experienced a number of eruptions over the years. The volcano overlooking the Bay of Naples in Italy is part of the Campanian volcanic arc formed over the subduction zone between the African and Eurasian tectonic plates. The...

One of the most deadly aspects of a volcano is the pyroclastic flow. This current of fast moving rock and molten lava can easily reach temperatures of over 1,800 degrees and travel at speeds over 100 km per hour. Contained within the fiery streams...

Volcanic gases are invisible and hazardous to collect therefore our knowledge of them is imprecise and limited. Normally when there is a volcanic eruption of any extent one gets as far away as possible. Reliable data comes from non-explosive volcanoes such as Kilauea on Hawaii...
