HOW DID EARTH GET HERE ?
Of
all the questions that humans face, the question of how the Earth
formed is one of the most challenging, and different theories that human
beings have been formed over the years on creation of the planet is
often generated much controversy.
While
scientists today believe that they finally found the answers to the
most basic question, it is important to remember that the previous
generations, people and culture they assumed that the answer to this
question is correct in their day as well. Here is some basic information about the most popular theory of how the Earth formed.
Development
of our planet began about 4.6 billion years ago, and the Earth has
undergone a startling change in geology since then. Earth has existed in some form for about a third of the history of the universe itself. Our
home planet formation starts with the early Hadean era, in which a
variety of solar debris accumulates into a world that is increasingly
crowded.
Very
little of it exists in its original form today, but scientists have
concluded that the main ingredient is the bedrock and the crystal. At
some point during this era, the young Earth to form the first coat just
before colliding with another large protoplanet, and many of the
problems on our planet was formed by this event. In
the chaos that followed, the Earth is setting the violence that is
constantly bombarded by meteorites and volcanoes was rocked by a great
and constant.
As the planet cooled, and things began to settle, the Earth entered the Archaean era. It
was during this period that our atmosphere was created, but the total
absence of the ozone layer and the scarcity of oxygen means that it will
be a difficult place to survive. However, the first fossils began to emerge during this time, and with it the story of life on Earth began. At
this time, the Earth is big enough to pull the building blocks of life
to the field of gravity, and accumulation of water started to create a
big ocean and sea.
In
these waters, life is slowly growing, and the possibility that the
early days of evolution, including the world's lifeforms are even more
diverse than the world today. Some
lifeforms found a way to build and store energy through the use of
sunlight and the abundant carbon dioxide, and oxygen created by the
basic form of photosynthesis is allowed to continue down the path of
evolution for the curious.
