NATURALES- TEMA 6. THE AERTH, INTERNAL AND EXTERNAL DYNAMICS

COSMIC EGG
14.000 million years ago all the matter and energy of the universe was forming the cosmic egg. The energy was so big thatthe big explosion happened, then, the universe start.
COSMIC EGG – BIG-BANG – UNIVERSE – MILK WAY – SOLAR SYSTEM

SOLAR SYSTEM
Components:
* Sun: Produce energy as light and heat.
*Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluton.
* Asteroids: Rocks fragments
* Comets: Rock fragments and frozen gases.

SUN
* Es una estrella pequeña ( smallstart)
* Tiene 4.600 millones de años
* Le quedan 5.000 millones de años
* Produce energy as light and heat

PLANETS

* Mercury Small, rocky, dense and close to the sunplanets
* Venus
* Earth
* Mars
* ASTEROIDS BELT
* Jupiter
* Saturn Big, gaseous, light(ligero) and away to the sun planets
* Uranus
* Neptune
* PlutonINTERNAL STRUCTURE OF THE EARTH

a) ACORDING TO THEIR COMPOSITION

CRUST: Is composed by aluminum silicates
MANTLE: Is composed by magnesium silicates
CORE: Is composed by iron and nickelACORGING TO THEIR DYNAMIC

¿Cuál es la relación entre esta clasificación y la otra?
* La endosfera es igual que el núcleo
* La litosfera es igual a la corteza mas los 50 primeroskilómetros del manto superior
* La mesosfera es el resto del manto superior mas el inferior
* La astenosfera es entre 100 y 200 kilómetros del manto superior

LITHOSPHERE
Is continuous moving overasthenosphere
Is divided into pieces called tectonic plates
As a result of this movement earthquakes and volcanoes are produced especially between two tectonic plates.

TECTONIC PLAQUES

*The movement of tectonic plaques produce:
Earthquakes
Volcanoes
Rocks (igneous and metamorphic)

EXTERNAL DYNAMIC OF THE EARTH
START: Reacciones nucleares– 2 átomos de hidrogeno – 1 atomo de...
