A big mining corporation is planning to replace an ex-roman settlement (over 2000 years old) that is also a unique natural landscape, with an open-pit cyanide-based mining operation in the middle of Europe in Romania.
40 tons of cyanide per DAY will fill up a valley and 4 mountains will disappear.
Stunning photos showcasing the diverse collection of landscapes found across the planet.
Have you noticed how the full moon looks bigger on the horizon than high overhead? Actually, the two images are exactly the same size — so why do we perceive them differently? Scientists aren’t sure, but there are plenty of intriguing theories. Andrew Vanden Heuvel unravels the details of focus, distance and proportion that contribute to this mystifying optical illusion.
This animation is made up of two images of Europe at night showing lights from sources in cities and along roads in 1992 and 2010. Bright areas highly correlate with high population density – such as the densely populated cities like London, Paris and Rome. Coastal areas are also more populated than inland regions, making the outline of Europe clearly visible in these night images.
This is just a basic display of the abundance of elements in the known universe, the Earth, the Earth’s crust, the ocean, the atmosphere, and the human body.
Sinkholes may vary in size from 1 to 600 m (3.3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may be formed gradually or suddenly, and are found worldwide.
