Evolution of Earth

 Our Glorious Earth 

April 22, 2021

Wishing you all a very happy Earth Day!!🌎 

April 22nd every year is observed as Earth Day. It was first organized in 1970 to promote ecology and raise awareness of the growing problems of air, water, and soil pollution. So please do your bit and let's together try saving our lovely earth. 

Our dear Earth, the perfect breeding ground for life to evolve. Earth has been called the "Goldilocks planet." In the story "Goldilocks and the Three Bears," a little girl named Goldilocks liked everything just right. Her porridge couldn't be too hot or too cold. And her bed couldn't be too hard or too soft. On Earth, everything is just right for living things. It's warm, but not too warm. And it has water, but not too much water. 

This wonderful sphere of mortal life, our home, and the only planet known to have an atmosphere containing free oxygen, oceans of water on its surface, and, of course, LIFE was formed around 4.54 billion years ago. Phew! a pretty long time ago, isn't it?  However, life began at least 3.5 billion years ago. So, I decided to part my knowledge about the evolution of the Earth with you all on this precious day.

And yes!! rightly guessed. Our today's topic is the EVOLUTION OF EARTH. 

A giant mass of water and mud revolving in space, providing us all the necessities, was formed quite a long time ago. But have you ever wondered how did this giant planet come into existence in the first place? I am sure you did. So let's dive into this astonishing story about the earth's formation. 

This all began eons ago when the whole universe was inside a bubble, thousands of times smaller than a pinhead(even smaller than a single atom) called the 'COSMIC EGG.' Then about 13.8 billion years ago the tiny bubble began heating up and generating energy until it finally exploded with a bang. And yes, this idea of the massive explosion was jokingly referred to as ''THE BIG BANG.'' But as time progressed and evidence piled up this concept and the name got stuck with the scientific community. 

Now, let's take a peek into the Big Bang Theory. So, after the explosion the universe that we know today was born, and with it, TIME, SPACE, and MATTER came into existence. And it all happened in just a fraction of a second. The universe kept on expanding. When the universe cooled down a bit the energy converted into particles of matter and antimatter. Out of these two, some brave matter managed to survive. PLEASE NOTE: just 1 second has gone by so far. Over the next 3 minutes, the temperature fell below 1 billion degrees Celsius. 

Now, the universe got colder to allow the PROTONS AND NEUTRONS to come together and form its first atom THE HYDROGEN!! After millions of years when the hydrogen gas clumped together stars and galaxies began to form. Later everything started to spin forming mighty wind and GRAVITY! And over time one such gravitational force from the remnant of a dead star started pulling the giant dirty gas cloud. This cloud got denser and denser in its center and formed an accretion disk:(accretion- In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk.)   Then in the next 10 to 20 million years, other small particles of dust, rock, and gas started sticking together, creating larger objects. Until, it became a sphere and large enough to be called a planet, and whoopie!! our young Earth was formed!! 

At this time Earth's surface temperature was a burning mess with seas of lava and a poisonous atmosphere. Not only that, various comets, asteroids, and other cosmic elements constantly attacked it from all sides making it boil more and more. 

But soon, things took a dramatic turn, and the cosmic attack reduced, and so the temperature of the Earth cooled down. WATER from the inside of the earth rose to the surface, formed steam, and rained back on the ground to form oceans. Even other meteors brought more water in the form of ice. So gradually, the earth cooled down and the surface formed a thin crust. 

Meanwhile, the volcanoes on the ocean's bed blew magma to the top which eventually cooled down to form volcanic islands that joined together to create a single giant continent called PANGAEA. And inside the earth the hot rock continued to move around, moving the crust below and breaking it apart through a process called Plate Tectonics. And as the Earth's crust moved around Pangaea broke apart and its pieces drifted away to create the continents we see today. 

And modern earth took its form!! A place we all can proudly call HOME!

Omg!! that was a lot of research😵😅 Anyways I hope you enjoyed today's post and Thanks a lot for supporting me and reading my posts. 😊
