how does the earth form?

Question

in sientific words

Answer 1

the "big bang" cause it.

Answer 2

Ok, so we start off with the big bang, 4.6 billion years ago. It constantly expanded and lots of debris were flying around space, and hitting each other, making smaller bits. Some really huge bits of rock have a gravitational force, because they are moving, and have a large mass; these huge rocks attract smaller rocks, and the whole thing gets bigger, until a planet is formed. The outer rocks of this planet are constantly putting pressure on the middle of the rock, then the middle of the planet turns really hot, and makes convection currrents in the lava, only leaving the top bits of rock on the outer parts of earth (tectonic plates), the tectonic plates move, volcano's and stuff are formed, the atmosphere is formed from the gases, and eventually life is formed, because of our earth being the right distance from the sun - not too hot, not too cold

Answer 3

Throughout space we see stars forming and many of these will no doubt have planets. The early solar syatem was a condensation of gas and interstellar dust which started forming into an accretion disk. As the central mass, what became the sun, condensed, it sped up its rotation according to the law of conservation of angular momentum. At that time is was what we call a protostar. The flattening disk of gas and dust, and also rock and ice, formed areas of density which started attracting and sweeping up the debris. These dense regions, still orbiting the sun, became the planets.
The earth was one of these. At first the earth was probably largely gaseous like Jupiter and Saturn, but when the sun condensed enough to start nuclear reactions at its core, it became a real star and its solar wind probably blew away most of the outer gas regions of the young earth, leaving behind a hot, still-accreting mass. Rocks like meteorites and asteroids continued to get swept up by the earth's gravity, causing the surface to stay molten for millions of years. Then it cooled and began to form a lithosphere, or rocky crust. Later outgassing of water vapor and gases created our oceans and atmosphere. Some believe continued bombardment of comets may have added significantly to the water on the surface.
As for anyone who says this scientific explanation is bad science because it can't be demonstrated or replicated, is simply engaged in anti-scientific, pro-biblical propaganda. I would like to see the creationists replicate *their* version of creation, or show any evidence for it whatsoever. Science determines many things with great reliability, through indirect forms of observation and evidence-gathering. Creationists determine by biblical authority, blind faith, and dogma. Evidence and observation have nothing to do with their views. Yet, we see protostars and planetary systems forming all over the galaxy. No hand of God, yet.

Answer 4

In sientific words: it didn't.

In scientific words: probably through ground rock (with natural minerals in) mixed with decomposed leaves and general foliage breakdown etc, meteror deposits and H2O through a period of millenia. I'd guess.

EDIT: you can't get much more scientific than Rhsaunder's comments! 'agglomeration', lol

Answer 5

Ideas about the formation of the world are not strictly in the realm of science. Any notions about the formation of the earth cannot be observed, cannot be repeated, and cannot be tested.

But we do know the answer to your question since the creator has told us:
In the beginning God created the heavens and the earth.

Answer 6

The earth was formed about 4.6 billion years ago from an agglomeration of gas and dust, at least some of which came from a supernova. It is possible that the supernova explosion created a shock wave which caused the agglomeration.

Answer 7

According to Bertrand Russell in 'The ABC's of Relativity" the earth was formed when "Big swirls have little swirls that feed on their velocity and little swirls have lesser swirls and so on to viscosity."

Answer 8

Firstly many rocks were flying around, as they collided together they formed one large rock, it fell into the inertial and gravitational pull and now orbits the sun.

Answer 9

Hot gasses which spins rapidly and then cool down over millenia.

Answer 10

lots of rock, glue and some water

Answer 11

it is form by the combine of dust called nebulae....
