Texto Cientifico

We can say that scientific texts are those in which scientific language is employed. Being all scientific language mechanism used for communication, whose universe is in any field of science, and this communication occurs only between specialists, or between them and the general public in any communicative situation in which channel established.

Scientific texts are those who belong to the pure experimental sciences, which study the physical realities of the world and are characterized by the search for general principles and laws that have universal validity. On the other hand, technical texts refer to applied science in its technological and industrial aspects. These technological sciences are studying the possible practical applications and derivations of the general principles and laws established by the experimental sciences.

The Solar System is a planetary system that is Earth. It consists of a group of astronomical objects that rotate in an orbit, effects of gravity, around a single star, known as the Sun, which gets its name.1 was formed about 4600 million years ago from the collapse a molecular cloud that created it. The residual material caused a circumstellar protoplanetary disk in which occurred the physical processes leading to the formation of the Solar System planetas.2 is located today in the Local Interstellar Cloud is in the Local Bubble Orion Arm , of the spiral Milky Way galaxy , about 28,000 light years from the center esta.3

Artist's concept of the Solar System and the orbits of its planets.

Most of its mass , approximately 99.85 % , lies in the Sol.4 June 5 Of the many objects that orbit the star, much of the remaining mass is concentrated in eight planets whose orbits are almost circular and passing within a nearly flat disc called up eclíptico.7 the nearest four considerably smaller Mercury , Venus , Earth and Mars , also called the terrestrial planets, are primarily composed of rock and metal.8 9 While the outer planets , gas giants also named as " Jovian planets " , are substantially more massive than the Earth . The two largest , Jupiter and Saturn, are composed mainly of hydrogen and helium , ice giants , as they also call Uranus and Neptune are mostly made up of frozen water , ammonia and metano.10

Artist's conception of a protoplanetary disk.

The Solar System is also home to several regions composed of small objects. The asteroid belt located between Mars and Jupiter , is similar to the terrestrial planets as it is composed mainly of rock and metal, this dwarf planet Ceres is located. Beyond the orbit of Neptune is the Kuiper belt and scattered disc , two linked to Trans-Neptunian objects composed of water, ammonia and methane mainly areas. Here are four dwarf planets Haumea , Makemake , Eris and Pluto , which
