The Earth and all the planets are formed 4.5 billion years ago with interstellar hydrogen gas and heavier elements previously formed in earlier stars that had exploded.
The Sun, a young star, consists almost entirely of hydrogen and helium, which are being converted into other elements by a process of fusion, which generates the energy radiated by the Sun. However, the Sun produces insignificant amounts of elements heavier than carbon, since this fusion requires much higher temperatures. Some stars do create heavier elements, and as they reach the end of their lifespans, they explode as supernovas, releasing these elements (and creating still more, notably the radioactive ones).
Sometime more than five billion years ago, supernovae had exploded in our neighborhood of the Milky Way galaxy, creating and spewing out vast volumes of heavy elements. A tiny percentage of this material (but still a huge amount by earthly standards) was captured in the disk of gas that would form our Sun. Scientists are beginning to discover planets around other nearby stars, indicating that terrestrial planets (formed of heavy elements) also exist around other stars.
Around 4.5 billion years ago, this gas coalesced into a small number of balls, one of which was the Earth. These balls, or planets, were very hot but cooled, forming an outer crust on the smaller ones. The Earth could have continued to cool until it solidified. However, with radioactive uranium as one of the heaviest elements, the Earth's core can maintain an extremely high core temperature almost indefinitely. The discovery of near-surface geothermal "hot rocks" provides an example of the same process.
The Earth's surface has not always had the same form or with the same continents as it has now. A process of plate tectonics has the continents drifting (at an incredibly slow but measurable pace) across the surface. They split apart and ram back together to form new land masses. The Himalayan mountains were formed when the Indian land mass pushed into the southern boundary of the ancient Asian land mass, folding the crust and forming mountains. Other mountains were formed by similar processes.
The Earth's crust was originally formed from igneous rocks, much like the rocks formed when lava cools. These rocks gradually weathered away into sand and silt, which were deposited in the valleys and on the ocean bed. Here, they were compressed into sedimentary rocks such as sandstone and shale. The earth's surface is constantly changing, and many sedimentary rocks were later uplifted to form new mountains.
where in earth is diamond formed?
It is formed when the Earth was being formed. As the Earth got bigger the iron seeped into the crust of the earth and kept going.
Uranium is formed by nuclear synthesis in supernovas and at the 'big bang'. When the earth formed Uranium became a part of the forming earth.
in which layer of earth are rubies formed
As earth formed, most planetesimals were attracted by the earth's gravity and coalesced with earth.
Generally, diamonds are formed in the Earth and not from Supernovas.
it is formed 2 miles away from the earth
It happened right when the earth was formed by other weird stuff.
The materials that formed the Earth are in fact OLDER than the Earth, because they were around BEFORE the Earth was formed. The Elements that you are made of were formed inside STARS before the Earth ever existed.
Considering the Earth was Molten when it was formed, the temperature has actually decreased.
all about the earth. precisely how the earth formed, and what happened while the earth formed it's countries which came to be continents
Pangea was the original landmass of Earth so it was probably formed when Earth formed.
seasons are formed by the revolution of the earth
Rock was formed when the earth was made.
No and no. Uranium was formed before the Earth formed. Even the uranium that's IN the Earth was formed before the Earth was formed, by the process of stellar nucleosynthesis. Also, the most stable isotopes of uranium do have very long half-lives, but they are still radioactive, meaning that they eventually will decay into other materials.
Earth formed by God
the water the earth was formed with
No, rocks that are 3.5 billion years were not present when earth was first formed. Earth formed about 4.6 billion years ago.
it was all formed by me
It is formed at the outer layer of the solid earth.
They're not formed here. They were formed in stars - mainly as they exploded.
in the earth
earth was rotating to fast and the elements of the moon flew off of earth and the moon was formed
scientists believe the earth was formed during this era precambrian
When God formed Earth it was called creation, or creating of the land. becoming of the land.
