A new theory of the formation of the ancient continents

A new theory of the formation of the ancient continents Facts

The structure of the Earth can be compared with oranges: its bark like skin, covered with a thick mantle. By its parameters bark 30-40 kilometers deep, and be looser than the thinner oceanic crust.

"According to the new theory, the first continental crust formed when tectonic plates collide, plunging oceanic crust into the Earth's mantle. There is partially melted at the approximate depth of 100 kilometers. This molten rock and formed the first continent, "- said study author Thorsten Nigel, professor at the Institute of Geosciences Steinmann in Bonn.

The earthquake in Tuva caused the Indian tectonic plate movement

December 29. Earthquake in Tuva, including, and what happened on the night of Wednesday to be associated with the gradual movement of the Indian tectonic plate deep into Eurasia at a rate of 4.3 centimeters per year, which will go on for tens of millions of years, said RIA Novosti head of the laboratory of the Institute of Petroleum Geology and Geophysics, Ivan Kulakov.

According to him, the heterogeneous composition of collision zone — the area of the lithosphere of Asia, in which "drives" India — permanently deformed as a result of forming mountain ranges. These deformations cause mechanical stress

Solar energy — saving for Africa

Solar energy — saving for Africa Facts

Fig. Photovoltaic solar cells, which operates the system of drip irrigation. Kalale, Benin.

Robert Freling, executive director of the solar electricity SELF, located in Washington, showed that for irrigation use of solar energy will be much more economical than the use of internal combustion engines with diesel fuel. The experiment of combining drip irrigation and solar energy in 2007 to save the dry regions of the world began in the villages Freling Dunkassa Bessassi and in the north of the West African country of Benin.

Originally the project was planned to install solar

Britain found a way out of the drought situation

Britain found a way out of the drought situation Facts

The beginning of spring for southern Britain was surprisingly warm, which set the temperature of 15-18 ° C, which is higher than on. Rhodes in Greece at the moment. However, along with the spring warmth in the region has an acute shortage of rainfall, is detrimental to the awakening of nature and wallets of citizens forced to pay for the additional cost of water for irrigation and other purposes.

Rainfall for each region of south-east Britain.

To resolve the situation in the regions, where in February fell by one-third less

China has developed a system for monitoring the Earth's crust

China has developed a system for monitoring the Earth's crust Facts

In March 2012, China had completed a system of monitoring the movement of the earth's crust, which aims — to predict earthquakes. Based on the satellite navigation system is a network of 260 permanent and 2,000 temporary observation stations, including data processing equipment. According to China's earthquake administration, to other purposes for which the monitoring system also provides weather prediction and research.

Experts involved in the project, the consensus is that the results concerning the sources of geoscience, comprehensive, accurate and diverse, and the data will be publicly available

Like a bolt from the sky — snow instead of an Indian summer, the island after the earthquake, showers instead of sandstorms

September 29, 2013. Storm mist — this week at the Capital Region poured nearly ten times the rate of precipitation and weather forecasters managed to upset half the country — instead of the promised Indian summer came to woman's winter. Mexico attacked simultaneously two hurricanes: from the Atlantic and the Pacific, Asia, the sky is pouring so hard that even the rainy season rate exceeded tenfold. It seems that abyss of heaven opened wide. And this is not the end — Europe already promised the coldest winter for a hundred years, and America — a powerful cyclone.

U.S. threatens sea-level rise

U.S. threatens rising sea levels Danger Zone

The lives of 5 million Americans are living at a height of a few meters above sea level, is really threatened by the consequences of global warming. Basically, it refers to coastal populations from Maine to the Gulf of Mexico and the west coast, where the water levels in the ocean of the risk of flooding has doubled.

Only one South Florida is under attack taxable property value of 30 billion U.S. dollars. In California, because of the changing climate in the next two decades will be exposed to the danger of flooding

Natural anomaly in Tver: the city blossomed lilacs

September 5, 2013. At that time, as the Capital Region is experiencing a prolonged autumn bad weather, the city's more than 100 kilometers north of Moscow blossomed lilacs.

Blossoming in September, there has been observed for the first year. According to experts, this is due to global climate change, and nothing good is. Unplanned spring will lead to the fact that in May, when it is necessary to blossom bushes, no flowers on them will be gone.

Floating city will save the planet

Floating city will save the planet save the planet

Chinese designer-architect Wei Zhao proposed his own version of clean high-rise building, exhibited at the skyscrapers eVolo-2012. According to the draft, the house will float in the air above the ground.

As planned by the developer, the main force that keeps the house, or a city in the air, becomes magnetic levitation technology of Maglev, allowing buildings to stay in the air, starting from the Earth's magnetic field. Molecular magnets principally responsible, will be in the lower part of the perimeter of the structure. The rotation of the magnets will also

Japan again threatens tsunami

Japan again threatens tsunami Natural disasters

March 13, 2012 on the north-eastern coast of Japan, an earthquake measuring 6.8. Since strong aftershocks continued, the National Weather Service warned residents of coastal prefectures of Aomori and Iwate, and the central and eastern part of the island of Hokkaido about a possible tsunami, but the warning was soon canceled.

The earthquake occurred at a depth of 10 kilometers at a distance of 210 kilometers from the northern coast of Hokkaido and caused heavy seas: Japanese coast waves reached 20 and 10 centimeters. Therefore the height of the proposed tsunami could reach half
