How Did Earth Form? Planet Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that formed the Sun and the other planets. 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 ...
How did planet Earth form: The Earth we know as home Over billions of years, Earth gradually becomes the safe, pleasant, life-bearing home we know today. Gradually, as our solar system cools and evolves, Earth goes from a hostile and volcanic molten rock to a lush and water-filled world.
How did all the water on planet Earth form see the details? Water is formed by putting hydrogen and oxygen together usually through the combustion of hydrogen with oxygen so where did all this free hydrogen and free oxygen come from? or where did all this water come from if it didn't come about by the combining of hydrogen and free oxygen ...
While no one knows for certain how the Earth formed, scientists theorize that it formed over 4 million years ago after the sun went through its initial formation, gravity began to draw heavy particles together into a planet and solar winds blew away lighter gases. These heavy particles became the core of the planet.
