Why the Sun is so important to the Earth essays Temperature of the surface : 5200 i 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, photosynthesizing Bacteria 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 humans organism to produce the vitamin D . Some of electric energy is produced due to the energy of sunlight. The Earths climate is controlled by the energy of the Sun . The heat of the Sun can be kept due to the Greenhouse effect. But not only positive effects has the Sun on Earth. Ultraviolet radiation can be harmful in large amounts and can cause sunburns and skin cancer. Flashes - the most powerful explosive processes observed on the Sun, are more exact in Its chromosphere. They can proceed all some minutes, but for this time energy which sometimes reaches 1025 Joules is allocated. About the same amount of heat comes from the Sun on all surface of our planet for the whole year. 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. If not to accept special precautions, there can put out of action complex space devices and solar batteries. Ther ...
