Earth evolution,just-born earth look like

What did the just-born Earth look like?

The jist-born Earth was like a blurred patch of blistering rock and choking fumes. However, space was cold, so the Earth also began to cool down. Approximately, 3,000 million years ago, the planet was cool enough for land masses to form. The centre of the planet was mainly melted iron. As time passed, the surface cooled to form the crust, which was mainly silica and the system condensed into water

How did the Earth start or iting the Sun?

The Sun's gravity caught the Earth, as well as the other planet,and pulled them into orbit around the sun. On one hand, the Earth's momentum was always trying to carry it always from the Sun's in a straight line. On the other hand, the Sun's gravity kept pulling the Earth toward the Sun. As a result, because of the centrifugal force, the Earth ended up orbiting the Sun in an elliptical path.

How far is the earth from the sun?

The Earth is the third planet from the Sun. It is situated at average distance (the mean distance) of about 150 million kilometers (93 million miles) from the Sun. However, the exact distance between Earth and the Sun varies with its position in its elliptical orbit.

When the Earth closest to the Sun?

The Earth is closely to the Sun around the first week of January, every years. The event is called Perihelion, and this point, the distance between the Earth and the Sun is about 147 million km (91.3 million miles).

THE REAL HISTORY OF EARTH,DEVELOPMENT,CHANGES,COMPOSITION,EVOLUTION, EXPLOSIONS

How old is our Earth? Scientists believe that our Earth was formed approximately 4.54 billion years ago. About 14 billion years ago, there was a massive explosion, which the scientists later named The 'Big Bang'. It relalised radiation, particles and huge clouds of atoms, dust and gas. Our Earth is believed to have been born as a result of this Big Bang. Where in Space our Earth located? Our Earth is located in a spiral galaxy named the 'Milki Way' which is  part of the solar system also consists of the Sun,the Moon,the other seven planets and their moons,numeeious comets,astroids andminor planets. The Solar System was formed from a large,rotating cloud of interstellar dust and gas called the 'Solar Nebula',orbiting the milki way's galactic centre. The Solar Nebula was composed of hydrogen and helium,created shortly after the Big Bang. How did the Earth form? After the Big Bang, particles were floating around in space. The force of gravity pulled the particl...
