Explanation:

HEY MATE .......

when Earth and the rest of the solar system first formed. The solar system began as a rotating cloud of stardust. “Dust, rocks, and gas” may not sound inspiring, but this cloud contained the 92 elements which somehow combine to form every corner – living and nonliving – of Earth.

Then the Big Bang (14 billion years ago) produced the atoms of hydrogen and helium. Elements as heavy as lithium followed the Big Bang within minutes.

Stars such as red giants fused hydrogen and helium nuclei to form elements from carbon (the foundation of life) to calcium (now our bones and teeth). Supernova explosions formed and ejected heavier elements such as iron (for red blood cells). We are not just “dust.” We - and our world - are stardust!

About 4.5 billion years ago, a nearby star exploded and sent a shock wave through the dust cloud, increasing its rate of spin.

As a result, most of the mass became concentrated in the middle, forming the sun.

Smaller concentrations of mass rotating around the center formed the planets, including Earth.
