why does the earth not implode from gravity?

Question

if gravity is a pull, why does the planet earth not adjust

Answer 1

It is a balancing act. Matter is drawn to the center of gravity as this happens pressure increases, temperature increases, volume increases away from the center. Matter pushes up, matter pushes down. At some point they reach an equilibrium. The sun woks the same way but on a totally different scale. But the principle is the same.

Answer 2

The earth has alredy contracted to an equilibrium state after millions of years from a gas ball to a rocky planet by gaining sufficient density due to its own gravity. Further contraction due to its own gravity is not possible.

Answer 3

Read the book by Bill Bryson - A Short History of Nearly Everything. It will answer your question and many more questions you might have about life on Earth and the Universe itself. It's an incredible book and easy to read. I hope you will check it out!!

Answer 4

Because the mass of the earth is not enough to create a gravitational pull that would cause it to collapse upon itself. Some stars do though. A supernova explosion is the result of a star collapsing upon itself and then exploding outward. Some stars collapse and become black holes.

Answer 5

insufficient gravity to overcome rejection forces between atoms and inside the atoms. to change that the mass of earth should be many times larger than the sun's.

Answer 6

because the earth has a core!
