When you are in Uganda, make a trip to lake Victoria. Only in this lake is home to fish, Marco, in other bodies of water the fish lived 300 million years ago. She is able to hold the inhaled air in the gills – so only makes a man: holds the air in his lungs. This fish represents the element of the so-called “adapter”, between the fish and animals on land. In addition to this unique fish in the lake full – full of crocodiles. Another phenomenon – an unimaginably rapid formation of new species and subspecies of fish – the phenomenon puts Darwin’s theory of evolution to a standstill, as he claimed that this is possible only over a long period of time. But the little fish from lake Victoria baffled not only the theory of Darwin, but of many scientists. On the same place in a few years it is again possible to observe a new appearance. And what absolutely fantastic – the ability to change the fish from this lake you can almost see already in the next generation, even if they live in your aquarium!
In addition to its rich underwater world and its inhabitants, the lake is also known in that it originates the sacred Nile. Victoria – the largest lake in Africa and second largest in the world. Fresh water in the lake is of excellent quality, Continue reading
American Arizona attracts tourists primarily for its red rocks, mysterious mirages and, of course, located here is the Grand canyon. But the wonders of nature in Arizona is not limited to, some of them even created as a direct result of human activity. For example, lake Powell is rightly considered the most beautiful artificial lake in the world.
Lake Powell, located on the border of Utah and Arizona, was created by the construction of a dam on the Colorado river in the Glen Canyon area. Although the construction of the dam and was met by numerous protests from ecologists and anthropologists, the project was completed on time, namely in 1963.
The shoreline of the lake is 3156 km and by this indicator it is not only a leader in the U.S. among the lakes, but this figure even more than the total length of the American coast of the Pacific ocean!
The maximum width of lake Powell reaches 40 km and depth of about 170 meters. It is of interest that the hydroelectric power station built on the dam, fully supplies electricity to five States of the USA.
Water not only fills Glen Canyon, and about 90 smaller canyons adjacent to it. The best Continue reading
11km NNW of West Yellowstone, Montana
Yellowstone is one of the largest known volcanoes in the world and the largest volcanic system in North America. The volcano is found above an intra plate hot spot that feeding the magma chamber underneath Yellowstone for at least 2 million years.
The giant Caldera is the product of a major collapse of the crust after 3 so-called ultra-plinian or Super-volcano volcanoes – large explosive events that occur several hundred to several thousand cubic km of magma. These eruptions happened 2.1, 1.3 and 0.64 million years ago.
Yellowstone is also the world’s largest hydrothermal system. It contains 182 Geysers, mud pools and fumaroles. The most famous feature in Yellowstone is old faithful geyser.
Future Super-volcano eruptions at Yellowstone?
Yellowstone Magma Chamber is considered to be still active and contain at least 15,000 cubic km of melt.
It can not be excluded and predicted that there will be another Super-volcano eruption at Yellowstone in the future (geological).
In recent years, the Caldera has been studied and monitored more closely. In recent years, Yellowstone demonstrates unrest in the form Continue reading
