Why the Sun is so important to the Earth
Temperature of the surface : 5200 î Ê Time of rotation : 25h (poles) 34h ( equator)The sun shines and warms our planet, without it life on Earth would be impossible not just for human , but for microorganisms as well. The sun is the main (though not only one) engine of processes occurring on the Earth. But not only its warm and light receives Earth. Various kinds of a sunlight and streams of particles render constant influence on its life.The oxygen on the Earth is produced by the plants in process called photosynthesis.Photosynthesis is a formation by the supreme plants, seaweed, photosynthesizingBacteria of the complex substances from simple (CO2 , H2O) due to the energy of light absorbed by a chlorophyll etc. photosynthetic pigments. One of the major biological processes, it is constant and in huge amounts made on our planet.Sun is also needed for human's organism to produce the vitamin D .Some of electric energy is produced due to the energy of sunlight.The Earth's climate is controlled by the ener
If not to accept special precautions, there can put out of action complex space devices and solar batteries. n Even if people can survive in this situation , it won't be enough sunshine for the human's organism to produce vitamin D . " Dutch scientist doctor Piers Van der Meer, the expert of the European space agency (ESA), believes, that some attributes testify that the Sun just about will blow up, news service Yahoo informs. But action of particles by it is not limited. In serious editions there are no Meer'sarticles on this subject. Streams of rigid x-ray radiation and the solar space beams, born at flashes, render strong influence on physical processes in the top atmosphere of the Earth and circumterraneous space. The heat of the Sun can be kept due to the "Greenhouse " effect. Flashes - the most powerful explosive processes observed on the Sun, are more exact in Its chromosphere. Fast particles cause strong currents in a terrestrial atmosphere, result in indignation of a magnetic field of our planet and even influence air circulation in an atmosphere. About the unusual processes occuring on the Sun, pictures of huge prominences, received solarobservatory NASA SOHO conducting continuous supervision over a star from space testify also. About the same amount of heat comes from the Sun on all surface of our planet for the whole year.
