The history of the Earth to be very precise, is concerned with
the evolution and development of the planet Earth in the Solar
System. It also refers to the series of events and periods that
paved the way to the evolution of life on Earth. All branches
of Science from the ancient times to the modern times have
made their significant contribution to understanding the main
events of the Earth from its past to the present. The age of
the planet Earth can be deduced to be around one-third of
the age of the entire universe. Several events related to the
geological changes have occurred in the timespan of the origin
and evolution of the Earth. These events have been related to
the formation of Earth in the Universe due to the various
extra-terrestrial events and the emergence of life on Earth. We
would discuss the process of the formation of the planet Earth
and the subsequent advent of life for the first time on Earth.
The geological changes occurring on the planet have been a
characteristic behavior of the Earth's crust since the primordial
times. The geological changes along with the biological changes
have been the root cause of the evolution of life on Earth.
Since the first evidence of life on Earth, species have continued
to flourish and get extinct at the same time. Even the process
of the continuous movement of the plate tectonics has played a
major role in shaping the continents and the oceans of the
Earth's crust. Several changes that occur in the biosphere of
the Earth like the ozone layer, the conditions of the different
types of soils, the proliferation of the various forms of the
greenhouse gases and the events leading to global warming –
all of these have played a major role in advancing the primitive
Earth to the planet what it has become today.
When considered in the modern phase of the planet Earth,
significant changes have been observed in the natural
environments since the time of the 1940s. Various forms of
developments in the field of technology have caused different
kinds of changes to the planet Earth. Man has been able to
explore deeper into the Universe and the Solar System with the
help of advanced technology. While global warming remains the
greatest threat to the existence of the planet Earth, several
awareness programs are being developed throughout the world
to make our planet a better place to live for the future
generations as well. After all – Earth is Our Home!
