What did Earth First Look Like?
In Earth’s Beginning
At its beginning Earth was unrecognizable from its modern form. At first it was extremely hot to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years the planet began to cool and oceans of liquid water formed.
How the earth was formed National Geographic?
About 4.5 billion years ago gravity coaxed Earth to form from the gaseous dusty disk that surrounded our young sun. Over time Earth’s interior—which is made mostly of silicate rocks and metals—differentiated into four layers.
Where did the earth come from?
Earth formed from debris orbiting around our sun about 4 ½ billion years ago. That is also the approximate age of the sun but it is not the beginning of our story. The story really begins with the Big Bang nearly 14 billion years ago which spewed hydrogen atoms throughout the universe.
Who was Earth discovered by?
Earth was never formally ‘discovered‘ because it was never an unrecognized entity by humans. However its shared identity with other bodies as a “planet” is a historically recent discovery. The Earth’s position in the Solar System was correctly described in the heliocentric model proposed by Aristarchus of Samos.
When was the first life on Earth?

How did life on Earth begin?
It seems possible that the origin of life on the Earth’s surface could have been first prevented by an enormous flux of impacting comets and asteroids then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 – 3.8 billion years ago.
How was the Earth formed in 5 steps?
Starting 6600 million years ago the stages involve the formation of the core the formation of the mantle the formation of oceanic-type crust the formation of ancient platforms and consolidation (the present stage) after which there will presumably be no more earthquakes or volcanic activity.

about 4.54 billion years ago
In a process known as runaway accretion successively larger fragments of dust and debris clumped together to form planets. Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) and was largely completed within 10–20 million years.

How long is 1 hour in space?
Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour while that person calculated that our clock ran for 59 minutes 59.9974 seconds.
