All you have to know about Planet Earth

The Earth is located in the solar system, and the third from the Sun, the eight planets that compose it. The "blue planet" as it is also known, is covered in more than 70% for water in the oceans, without considering the rivers and seas that are in the dry part of the planet. Comprising five continents, dry area has 148 647 000 Km2. Since the oceans have an estimated 361 million Km2 area, harboring various forms of life, aquatic animals and plants. It is the only planet that has living creatures have news.

     In spatial level, has a very important feature that there is life inside: the existence of atmosphere. It is composed of several gases, the nitrogen, oxygen and argon three main atmospheric gases. It serves a number of purposes, among them, protect the Earth from ultraviolet rays and provide oxygen for respiration of living organisms. The Earth performs translational movements, which is the movement around the Sun, lasting 365 days (one year) and the rotation motion around its own axis, which lasts about a day (24 hours).

     The Earth has several layers inside. The crust is the outermost layer and where we live. She, along with a layer above the mantle is called the lithosphere, which is totally solid. Below the mantle there is a composite of silicon, iron and magnesium layer. The inner core is having a liquid portion and a solid, even though at very high temperatures.

     Lithosphere in the region is that the tectonic plates are located. These plates are pieces of the lithosphere along the whole earth. The earth has seven major tectonic plates and many smaller ones. They get a "fitted" into the other and this area is that between a plate and the other are the points of occurrence of earthquakes and volcanoes. This is because when a "rub" the other plate results can be active volcanoes, earthquakes, tsunami and others.

     Its shape is not perfectly round, but slightly flattened and inclined about 23 degrees. This inclination indeed influences, with the translation, to determine the seasons (winter, summer, fall and spring). It has a mass of approximately 5,973.1024 and volume of around 1,083. 1012 is the largest of the solid planets, since other planets bigger than Earth, the solar system are gaseous. Itself has several imaginary lines, such as the tropics of Capricorn, Cancer, the equator (the line that cuts the earth in half dividing it into north and south) and the Greenwich meridian (also stains the earth in half, but this time vertically, dividing into east and west) sides. Not only are these lines, there are several tropics and meridians, helping, for example, to set the time zone in different cities of the world.

     But to get at the planet we live on and for him to gain such training were formative years. According to evolutionists were over 4.6 billion years. For creationists were 6-10 thousand years. The differences between these two currents do not stop there: how the Earth formed, how life originated and how life might possibly end up also matters that the two lines of reasoning found no common point.

History of Earth 


There are two theories to explain the formation of planet Earth. The known discrepancy between the creationist and evolutionary theory still yields discussion worldwide.
The first, a creationist, believes that a higher being responsible for the origin of life. For them God made the whole planet, as well as plants and celestial bodies.
