Origin Of The Earth

Origin 

 

 Like the other planets , the Earth is made up of molecules . These molecules were floating around in space , in a cloud of dust left over by the formation of our Sun . At first , just a few molecules clumped together .Then , the clumps began to crash into each other and stick together to make bigger clumps . Later , there were big crashes as pieces of metal and rock hundreds of miles across smashed into each other . There were huge clusters , one such cluster that formed about 150 million kilometers (93,205,678.8 miles ) from the Sun was planet Earth . The planet formation was largely completed in 10 - 20 million years .

Orbit
The Sun's gravity caught the Earth , as well as the other planets , and pulled them into an orbit around it . On one hand , the Earth's momentum was always trying to carry it away from the Sun in a straight line . On the other hand , the Sun's gravity kept pulling the Earth toward the Sun .

As a result ,through centrifugal force , the Earth ended up going more or less in a circle , about 148,059,648 kilometers (92 million miles ) away from the Sun .

Geography ;The Early Earth

The Early Earth    The early Earth was like a blurred patch of scalding rock and chocking fumes . But the space , in which it was floating , was  cold so the surface of the EARTH also began to cold , So the surface of the Earth also began to cool down . Approximately 3,000 million years ago , the Earth was cool enough for land masses to form . Even so , our planet remained an alien world for the next several hundred million years . Rafts of solid rock drifted in the magma like dark ice floes .   Atmosphere ,Weather and Oceans -) Gases , carbon dioxide , nitrogen , gusted out from the cooling rock and enveloped the planet in a blistering atmosphere devoid of oxygen . As the Earth cooled, the steam began to condense into water , and the water ran down wherever the rocks were lower , which perhaps made the first oceans . These first oceans may have been short-lived . Space rubble  left over from the birth of the planets bombarded Earth continuously .   ...
