THE CONCEPT OF THE WORLD AND THE WORLD


Layer of air surrounding the earth. Greek "ATNOS": steam and sphaira ", the word ball.
Varies depending on the amount Atmosphere
Animals and plants can live only in the atmosphere because the atmosphere outside the danger of them (shooting stars, UV and cosmic rays), protects and heat, and live for substances such as oxygen, which are absolutely necessary. To do this, astronauts, constantly, can live the artificial creation of an atmosphere in the cabin or space suit.

The higher above the ground, the mood is not uniformly understood: pressure, density, temperature and composition, increased drastically changed. Sıfırken height, ie the sea level, the thickness of the burden we all carry the air around the Earth. Air pressure is very important that this burden is, more falls kg cm l (L 033 g). We, the pressure is reduced. This event is very high hill, mountain climbers, for example tırmandıkları Himalayas (8,000 meters) to understand better time. As for the astronauts, the space will be released if they are clothes, and places the world on all sides there literally explode under pressure.

The atmosphere is 500 km into the air

The temperature varies in the same manner as before is reduced, then gradually reaches a very high degree, a few hundred. The atmosphere, the temperature change in the vertical direction in mind is divided into the following layers: the troposphere (the higher temperature, a certain rate decreases), the stratosphere (a condition called the heat does not change), mesosphere (from the heat rises, then decreases), thermosphere (increases at higher temperature).

Indispensable in a conservation area

The sun, UV rays or other radiation emitted light that illuminates us, but the ultraviolet rays that are dangerous, that from the ground when they bulunmazdı ulaşabilseydi the opportunity to live on Earth. Fortunately, up to 25 kilometers, or less stopped on the rays of the ozone layer. But some of them infiltrated the atmosphere still reaches the ground. Woe to the careless sun for a long time without measure!

All weather events in the atmosphere resulting from the movements. These movements created by the rain to let go of life to go on Earth.

Space

It shows on the contrary, a very small number of universes in a space largely consists of much more than material objects: in fact, the heavenly bodies, the stars of boşluk'ta had only one. The smallest level of matter, which is quite a big gap between the core electrons in the atom is.

Since ancient scholars such as Aristotle, "hate nature cavity you're from. This is one reason, the old science of physics to connect, to explain some of the events that have been created by a famous phrase.

Italian physicist Torricelli (1608-1647), but XVII. Century. During the experiments on atmospheric pressure, barometric gap proved by the opposite. In 1654, the German Otto von Guericke discharging the air in a glass vase, the air discharge machine was invented.

Today it was being developed for all laboratories and industrial tools (rotary pumps, hoses, water or mercury). All of these machines exactly boşaltamazlar air or gas, because each of them has a place. Also in interstellar space is not complete: be reduced in density of gases and particles.

Equal weight, regardless of all objects in space decreases rapidly. Space, at a lower temperature than the boiling temperature of liquids offers. Space is the protection of cold food in combination with (canned) help (airless boxes) are used.

In which there is no conductive material does not transmit sound, which is an excellent insulator against heat. In contrast, cross the beams is why we are the warmth of the sun: The sun's warmth shines through interplanetary space heats up the earth again thanks to this room, the cloudless nights, although they are far away are the light of stars We can see clearly.
