How was the earth formed?

Question

oder dan big bang
n de bible

Answer 1

HARD !!!

Answer 2

It's a long story but i can tell you a shortcut...billions of years ago there was the so called " big ban " a big explosion which had recreated the universe...i believe. After that explosion, the matter started to get cold and so the planets on the solar systems were formed. And so the earth was formed. It is possible that the moon is a part of the earth which had formed after a big impact while the earth was still in a very hot and liquid form. Sorry for my spelling and my english...

Answer 3

The earth was formed from the accretion disc around the young sun. This accretion disc was a large disc of gas and dust that orbited the sun. As dust particles moved around, they started to bump into each other, stick together and form the planets.

Terrestrial planets like the earth were mainly made from this dust, while the gas giants like jupiter started as a smaller lump that started to attract more gas than dust.

Answer 5

The earth was formed by God Almighty. In otherwords the earth was framed by the word of God. If you read through the whole of Genesis chapter one in the holy bible you will get to understand why and how God formed the eath.

Answer 6

From the Big Bang, from which the universe emerged, and massive dust clouds then form planets.

Answer 7

The Formation of the Earth
After the big bang explosion (approximately 12 billion years ago), much of the matter of the expanding universe coalesced into stars. The nuclear fusion reactions of these stars gave rise to the 92 naturally occurring elements and their isotopes in the known universe.

Approximately 5 billion years ago, one of the aging stars in the Milky Way galaxy "exploded", sending a cloud of matter into the galaxy. Most of the lighter elements (hydrogen and helium) rejoined to form our sun, while the heavier elements formed a flattened disk of matter that orbited the newly born star. Over time (more than 100 million years) this disk of matter began clumping together in a process called collisional accumulation to form larger aggregates of matter. As the size and gravitational pull increased, the stellar debris clumped into millions of planetesimals, which grew into a much smaller number of planetoids, which eventually grew into the nine planets of the solar system, their moons, and a host of other solar system materials.

The young Earth formed approximately 4.6 billion years ago (give or take a few million years). The age of the Earth has been determined by radioactive dating techniques which measure the decay sequence of potassium-40 to argon-40, uranium-238 to lead-206, and a host of other radioactive decay series. The Earth formed a structure somewhat like a jawbreaker piece of candy in that is has four distinct layers plus the atmosphere, one on top of the other. From inside out we have:

the inner core composed of solid, crystalline iron and nickel;
the outer core, which is a liquid layer made of molten iron, oxygen, and sulfur compounds;
the mantle, which is a molten, quasi-liquid layer made up of silicon, aluminum, and magnesium oxides;
the crust, composed of lighter elements (mostly silicon and lighter mantle compounds) above the mantle. The crust is composed of two distinct parts - the continental crust, which is made up of low-density granitic rocks such as quartz and feldspar that "float" on top of the mantle, and the oceanic crust, which is the earth below the oceans composed of basaltic rocks rich in elements from the mantle;
and the atmosphere, that is composed of variety of gases (nitrogen, oxygen, carbon dioxide, argon, etc.), which have changed throughout Earth's history.


The early Earth's atmospheric composition is not completely understood. It's composition was either one of two possible scenarios:

A Reducing Atmosphere - This hypothesis states that the young Earth would have had no free oxygen due to the slow coalescence of the Earth. Exposed iron formed compounds with free oxygen, "locking" it away from the newly forming atmosphere. In this scenario, the primitive atmosphere would have consisted of water vapor, hydrogen, nitrogen, methane, ammonia, and trace amounts of carbon dioxide and carbon monoxide.
A Mildly Oxidizing Atmosphere - This idea states that the primitive atmosphere had small amounts of free oxygen present that came as a result of a rapid formation of the Earth. It would have generated large amounts of heat, melting most of the iron and drawing it closer to the core very quickly. This allowed oxygen to be present in trace amounts, along with water vapor, carbon monoxide, carbon dioxide, nitrogen, sulfur compounds, methane, and ammonia.
Liquid water appeared on the Earth's surface starting around 4 billion years ago. We know this from the evidence of sedimentary rocks (which require water to form) that have been found in the Isukasia Region of Greenland that date to over 3.8 billion years old, and gneiss from the Canadian Shield of the Northwest Territories near Great Slave Lake that date to 3.96 billion years old. For the first 600 million years, the Earth's surface was too hot for liquid water to have existed on the surface. Water vapor was released from the abundance of volcanoes, from comets (composed largely of ice and organic compounds), and meteors (also possessing organic compounds). As the water vapor condensed, fell to the Earth's surface, and was vaporized by the hot surface temperatures, the water was cycled back into the atmosphere. This water cycle lasted for over 600 million years. From the constant cycling of this slightly acidic water, small pools and ponds began forming on the continental crust. As the runoff from the granitic continental crust eroded away minerals and salts, they were carried into the oceans and seas, where we now have a 3% salt solution in our oceans.
