An outline of tsunamis and their destructive force
By: Christyl Rivers
The destructive Tsunami that hit Japan in March of 2011 was the result of a powerful point nine earthquake. It is both the magnitude of an earthquake and the geology of land and sea that affect a tsunami's intensity. The even more destructive Indian Ocean...

Try this experiment: Toss a coin into a kitchen sink filled with water. See the concentric circles rippling out from where the coin dropped into the water? That's the pattern of the giant killer ocean wave known as a tsunami. "Tsunami" (soo-nah-mee) is a Japanese...

How sand dunes are formed
By: Jose Juan Gutierrez
Sand dunes are collections of grains of sand, forming hills, ridges or mounds, that accumulate on the shoreline by the effects of wind and sea waves. Sand dunes may vary in form and size, depending on the type of sand and the wind´s direction...
Facts about the earth's magnetic field
By: Jose Juan Gutierrez
The Earth´s magnetic field (geomagnetic field) is an enormous invisible shield of magnetic field lines surrounding the Earth. The magnetic field protects the Earth from the charged particles (solar wind) coming from the Sun. The magnetic field extends from the Earth´s liquid outer...
The importance of Earth's magnetic field
By: Jose Juan Gutierrez
The Earth´s magnetic field, also known as the geomagnetic field, is an immense invisible shield of magnetic field lines encircling the Earth. The magnetic field protects the Earth from highly charged particles leaving the Sun. The Earth´s magnetic field surrounds planet Earth, extending...
Should we start preparing for the end of the world?
By: Christyl Rivers
It really is the end of the world as we know it. Watch this Ted video to learn some reasons why. Although it is the end of the old world, for many optimists it is the beginning of a new, and improved world. The fact...

Air pollution can be measured in one of two ways. Source monitoring, which measures the pollutants as they are emitted from a source, seeks to determine the mass of polluting material that is contained in a volume of emission (i.e., mass of pollutant/volume of...

The Northern Lights, aurora borealis, is the name given to certain bright displays of light which are frequently seen in the skies above the higher latitudes, i.e. towards the Arctic Circle, (Southern Lights, known as aurora australis, can be seen southern skies) and these...

Remember that school science project that mixed baking soda with vinegar to create a "volcanic eruption"? The same two ingredients can be mainstays of a personal program to reduce pollution by substituting for harsh chemical cleaners that harm the environment. What's more, using baking soda...

Pollution is contamination of the natural atmosphere by human activity. The source of this contamination can be a man-made chemical, a natural mineral, biological waste or any form of energy, such as sound. Pollution is everywhere; we cannot miss it. It is responsible for damage...
