how was earth formed?

The Earth and other planets in the solar system are believed to be had formed out of the solar nebula. Solar nebula was the disk shaped mass left over after the formation of Sun and still considered as the place of origin of new stars. It happened about 4.54 billion years ago.

he earth was formed in the same way as the sun, planets, stars. At first the earth was a hot glowing ball of white hot gases with a temperature that was millions of degrees Fahrenheit. This was caused by particles of gases being drawn together and compressed, giving off a lot of heat. This happened millions of years ago.

Finally the earth cooled down. The ball of gas slowed down from spinning and the color changed from white to yellow to red to not giving off any light at all.

The earth contracted, getting smaller and the gases changed to liquid as they cooled. Heavier materials drew to the center of the earth. The heavier liquid settled at the middle of the earth. As the earth cooled more, a solid crust formed over the over the liquid material. As the crust cooled, it got wrinkled and burst open in spots. Gradually cracks formed in the crust. Water that formed under the earth's crust escaped from the cracks in the earth and soon water vapor formed above the earth. This lead to cloud formation. Larger droplets formed in the clouds and as they were pulled to the earth by gravity came the first rainfalls. The rain at first evaporated as soon as it hit the earth. Later, as the earth continued to cool, the rain stayed on to form lakes and oceans. At first the water was all fresh water, but as it had chemicals from the earth's crust mix in, the water of the oceans became salty. At one time the earth was all water on its surface.

Later pressure and heat in its center pushed up solid portions of the earth that became land forms. Sometimes the land would sink back down and other portions arise.

About three million years ago, the earth cooled a great deal and great sheets of ice called glaciers covered its surface. As the ice spread over the land, it gouged great valleys, rivers and lakes into the earth. About 8000 years ago the last glaciers melted, with the earth more as it is today.

earhnfor formed billions of years ago due to big bang.

here is a detail-

Planet Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that the Sun and the other planets were formed. However, Earth then was very different from Earth now, and it would have been impossible for life to exist on it. In fact, it is only quite recently in the Earth's 4,600,000,000 year long life that life, resembling modern-day life, has been possible, first with the dinosaurs over 200,000,000 years ago and now with humans and other animals. The Earth is still being formed now. It still has a molten centre which causes volcanoes to occasionally erupt, and plates on the surface are constantly "swimming" meaning that they collide with other plates and cause earthquakes. On this page, we will look at how Earth may have settled to become like the planet it is now.
