When was the earth all connected?
Pangea existed between about 299 million years ago (at the start of the Permian Period of geological time) to about 180 million years ago (during the Jurassic Period). It remained in its fully assembled state for some 100 million years before it began to break up.
How did the world began?
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
What is the origin of Earth?
About 4.54 billion years ago, through accretion of small planetoids, numbering in thousands, an entity which we call proto-Earth formed. Our planet grew through accretion of these planetoids and their collisions. This generated a tremendous amount of heat.
How did the Earth’s First continents form?
About 500 million years later, the first continental crust formed. These continents drifted on a sea of mantle, causing plate tectonics. They drifted and collided over millions of years, to create the world as we know it today. With further cooling, clouds formed on Earth, causing the first rains and creating oceans.
How were the terrestrial planets formed?
Over a period of millions of years, they coalesced through collision and condensation to form the terrestrial planets. One such planet, which was the aggregation of such small planetoids, created 150 million kilometers away from the Sun, was Earth (rather the proto-Earth).
How did the Solar System create the Earth?
Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium, from the closer regions, leaving only heavy, rocky materials to create smaller terrestrial worlds like Earth.
