Earth

The earth - our homeland planet. From all planets of our solar system we know it best. Of the structure of the earth up to the first life natures, from the atmosphere to the water. All this is singular - we know up to now from only one planet, on which there are lives - the earth. Water in the liquid condition gives it only on earth - probably the most important reason for the life.

The Atmosphaee around our planet developed approximately in millions of years - coincidence? Purely theoretically this expiration could take place also on another planet - or already gives it to lives outside of the earth? Air is separated from the ozone layer with the universe. Air is not weightless, but approximately around the earth of thousands of Kilos heavily. Therefore it is held also by the attraction of the earth.

The inside of the earth is liquid and/or because of the positive pressure zuinnerst already again firm. The terribly high temperatures let the rock melt. The earth's crust - our soil - is relatively thick to the 40'000 kilometers in the interior of the earth a thin Haeutchen, i.e. straight times 40 kilometers.
