THE UNIVERSE AND OUR PLANET

good morning, welcome to my blog.

Today I will talk about a work entitled Natural sciences
THE UNIVERSE AND OUR PLANET
THE UNIVERSE:
What way?

The universe is formed by spaced apart by great distances galaxies.
the galaxy can be grouped to form clusters of galaxies and star clusters they are also.
the stars are formed primarily and hydrogen and helium.
within galaxies or in the periphery can be found groupings of stars called star clusters.
Also in the stars of galaxies there are clouds of gas and dust called nebulae.
Our galaxy is called the Milky Way.
One of the more accepted theories he origin of the universe is the Big Bang theory.
That has some measures and distances in astronomy and units, of which defines it
Astronomical Unit (AU) is the average distance from the earth to the sun 150 million km.
Light year is the distanc
e light travels in a year, which is 9.5  km.

MOVEMENTS OF THE PLANETS AND EARTH STATIONS

MOVEMENTS OF THE EARTH

They are the rotation and translation
Rotation is the imaginary line that runs through the north and south geographic.
Equatorial plane is an imaginary plane perpendicular to the earth cut in half.
Ecuador is the imaginary line that separates the two hemispheres.
Ecliptic plane is a plane that cuts in half the sun.
rotational movements are completed every 24 hours.
Translacion when land is making moves around the sun.
and completed in 365 days, which is determined Earth year.

THE STATIONS

There is an important inclination causing the earth to be temperature differences as a result of this difference seasons occurs.
The days pass from summer to fall and winter to spring is known as EQUINOCI the day and night is equal to 12 hours.
The days of autumn to winter and spring to summer is called Solstici which is the difference between day and night.

APPARENT MOVEMENT OF THE SUN

From the ground the sun revolves around the earth.
Summer the sun rises in the east and the sky gets too high.
Winter sun rises in the east and rises slightly to heaven.
Spring the sun rises and sets every day a little north.
Autumn sun rises and sets every day a little further south.

MOVEMENTS OF THE MOON

There are two types of movements
M. rotation-turns on her and takes 28 days to complete.
M. Voltan Translacion- the earth draws a nearly circular orbit that takes about 28 days.
is the eclipsis which has two types:
Eclipsis the sun and the moon Eclipis.

THE TIDES

The earth and the moon attract each other because of the force of gravity.

SOLAR SYSTEM

It consists of two models:

M. GEOCENTRI-
 according to this model encontrava land in the center and all the planets revolve around it.
M HELIOCENTRICO- 
In this model the sun is still the center of the universe and all the planets revolve around the the.
This is the astronomical NICOLAU propueso COPERNIC.

THE STRUCTURE OF THE SOLAR SYSTEM

The solar system will lead to more than 4,500 million years from a nebula.
Solar structure is constructed by a series of Cocentricas areas called orbits.
They also have some small fragments like asteroids, which are located in two regions.
the asteroid belt and the Kuiper Belt.

THE PLANETS

These rocky or gaseous
Rocosos- Mercury, Venus, Earth and Mars
Gaseosos- Jupiter Saturn, Uranus and Neptune,

EARTH, A UNIQUE PLANET

The components of the earth are.
Geosphere and metal rocky part of the planet.
Hidrosfera- is made up of all the water on Earth's surface.
atmosphere-is the gaseous layer that surrounds the planet.
biosphere is the set of all living creatures on earth.
