THE EARTH

THE SOURCE OF LIFE

WHY IT IS THE PLANET OF LIFE?





Scientists have been able to reconstruct detailed information about the planet's past. Earth and the other planets in the the solar system formed 4.54 billion years ago out of the solar nabulo , a disk-shaped mass of dust and gas left over from the formation of the Sun. Initially molten, the outer layer of the planet Earth cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object (sometimes called theia) with about 10% of the Earth's mass impacting the Earth in a glancing blow.Some of this object's mass would have merged with the Earth and a portion would have been ejected into space, but enough material would have been sent into orbit to form the moon.
Outgassing and activity produced the primordial atmosphere. Condensing water, augmented by ice delivered by The highly energetic chemistry is believed to have produced a self-replicating molecule around 4 billion years ago, and half a billion years later.





The development of allowed the Sun's energy to be harvested directly by life forms; the resultant accumulated in the atmosphere and resulted in a layer of (a form of in the upper atmosphere. The incorporation of smaller cells within larger ones resulted in the True multicellular organisms formed as cells within colonies became increasingly specialized. Aided by the absorption of harmful by the , life colonized the surface of Earth.As the surface continually reshaped itself, over hundreds of millions of years, continents formed and broke up. The continents migrated across the surface, occasionally combining to form . Roughly 750 million years ago (mya), the earliest known supercontinent, , began to break apart. The continents later recombined to form , 600–540 mya, then finally , which broke apart 180 myaSince the 1960s, it has been hypothesized that severe action between 750 and 580 mya, during the , covered much of the planet in a sheet of ice.

THE SOLAR SYSTEM


INSIDE THE MILKY WAY THERE ARE MANY SOLAR SYSTEMS BUT WE CARE ABOUT ONE WHICH IS OUR SOLAR SYASTEM


IT HAS 9 PLANTES, ONE SUN AND THE MOON




LETS START WITH THE SUN



SECOND, THE Mercury







Third Venus









FOURTH, EARTH








FIFTH, Mars














SIXTH, Jupiter












SEVENTH, Saturn







EIGHTH, Neptune







NINETH, PLUTO

Where We Live?


IF WE GO DEEP INTO OUR SPACE
WE WILL FIND THAT WE LIVE IN A GALAXY
IT IS CALLED "THE MILKY WAY"
WHT YOU KNOW ABOUT IT?


The Milky Way (a translation of the latin Via Lactea, in turn derived from the Greek Γαλαξίας (Galaxies) sometimes referred to simply as "the galaxy"), is a barrade sperial galaxy that is part of the local group of galaxies. Although the Milky Way is one of billion of galaxies in the observal univarse, the Galaxy has special significance to humanity as it is the home galaxy of the planet earth. The Milky Way galaxy is visible from Earth as a band of light in the night sky, and it is the appearance of this band of light which has inspired the name for our galaxy


Some sources hold that, strictly speaking, the term Milky Way should refer exclusively to the observation of the band of light, while the full name Milky Way Galaxy, or alternatively the Galaxy should be used to describe our galaxy as an astrophysical whole. It is unclear how widespread the usage of this convention is, however, and the term "Milky Way" is routinely used in either context.
