High Speed Avalanches
Although an avalanche can mean the fall of any material e.g. snow, soil and even rocks, in common usage it generally refers to a falling mass of ice and snow which breaks away from the side of a mountain or cliff and surges down at great speed.
Preserve Your Body In Ice Like Otzi
Did you know that under extreme cold the human body can be preserved over 1000’s of years. A great example of this was during September 1991 when hikers in the Otztal Alps came across the body of a man who turned out to be over 5000 years old. He was preserved in an airtight pocket beneath a huge glacier.
Water Can Crack Metal
Â
Did you know that water can expand in volume by around 1/9th of its total composition. This means that when frozen it occupies more space than when in liquid form.
The above phenomena is very common in houses where water pipes burst over the winter due to ice forming in the pipes. The pipes which were [...]
Global Warming Is Real
Â
The arctic ice is receding and global warming is no longer a theory but a reality. Scientists predict that by the year 2100, the average surface temperature will jump up by 6 degrees Fahrenheit. Nighttime temperatures will be higher and there will be hotter days.
Since air temperature is a powerful component of climate, there will [...]
Tornadoes : High Speed Destruction
A tornado is generally perceived to be one of the most violent weather disturbances you could ever face. The extremely fast whirling winds mean that tornadoes can travel for many miles at great speed causing massive destruction, death and cost to the people and environment they hit. As an example one tornado traveled for 293 miles across the USA crossing [...]
Autumn Trees & Leaves
Autumn is a time of great beauty with trees turning from a bright green to shades of brown and red, but why do these leaves lose their green color and become the yellow, orange, and red we associate with Autumn?
Well when the air temperature drops the chlorophyll inside the leaves starts to break down and [...]
Hibernation, Migration & True Grit
Â
Winter is a hostile season for both animals and humans but interestingly both approach the cold in different ways. Whilst humans will survive by keeping their homes insulated and wearing several layers of clothing animals take a slightly different route ? In fact scientists studies have shown that most animals fall into one of three [...]
Pollution Problem: The Household
Â
The ever rising problem of pollution and greenhouse gases are not just generated from the exhaust of your automobile’s engine but from your house as well. Its a well known fact that more pollution is emitted from the average home compared to the average car.Â
In fact, the average home generates about 200,000 lbs or more of [...]
