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!
