No longer are mobile phones simply devices for making and receiving phone calls. No longer are the plethora of personal digital assistants only for organizing data, and hence your life. Today, smartphones combine the best features of both these devices and then add much more.

Volcanoes – Science Article

Volcanoes

Volcanoes have been in the news a lot recently, one volcano in particular located in Iceland at the Eyjafjallajökull glacier, which brought Europe’s air travel to a halt.  But what is a volcano?  I’m going to try and explain them, but don’t forget I’m not a volcanologist.  Volcanology is the study of volcanoes.

The first thing you have to understand is the structure of the earth, there are three layers:-

1. The Crust: The crust is the outer layer of Earth. It is made up of plates about 18 miles thick, these plates sometimes move. It is the bit we live on.
2. The Mantle: The second layer is called the mantle. It is about 1,800 miles thick.
3. The Core: The inner layer is called the core.

Between the Earth’s crust and the mantle is a substance called magma which is made of rock and gases.  When plates on the surface collide, one plate slides on top of the other, the one beneath is pushed down.  Magma is squeezed up between the plates.

Earthquakes

An earthquake (also known as a quake, tremor, or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves.  At the Earth’s surface, earthquakes manifest themselves by shaking and sometimes displacing the ground.  Any activity within the earth that creates vibrations can be called an earthquake, whether it’s a natural phenomenon or an event caused by humans — something that generates seismic waves.  Earthquakes are caused mostly by the rupture of geological faults, but also by volcanic activity, landslides, mine blasts, and nuclear experiments.  Earthquakes send waves through the earth and this means that places many miles from the centre of an earthquake can be affected by these waves.
