The Making Of the Planet
Where did planet earth come from? How did everything start? Scientist has figured out how things were like millions of years ago and its secrets. They have discovered how life started and how it has evolved. This is the story of how the only planet known to hold life came to be, and how life on earth started.
When our solar system first started only our young sun existed, so where are the planets? Dust and debris is only thing surrounding the sun, but as million of years pass gravity takes hold and rock is compressed and collected until a large planet has formed. The surface of the earth right now is barren and no life can be seen anywhere. Volcanic activity starts up and spews hot lava and magma across the surface of the earth. From space the planet looks more like hell then Earth. Unaware of an incoming planet, earth continues to spew lava from its core; the young planet appears hurtling toward the earth at 20 times the speed of a bullet. As the planets collide and reform a smaller chunk of it becomes our moon. The planet is set spinning and days only last for 4 hours. Earth starts getting bombarded by millions of meteorites; these rocks carry small amounts of water and other elements and minerals vital for life on earth. Pools of water start to form until whole oceans are created. Our moon is fully formed and it is so close to the earth that it is creating super waves and storms. Soon the moon pulls away from the planet the world spins more slowly and the water calms. Deep in the water many volcanoes start to form creating islands when they surface, these are some of the first volcanic islands ever. Planet earth is very hot and still getting bombarded by waves of meteorites; these meteorites sink into the oceans and dissolve into proteins and primitive acids. Also under the sea under water chimneys spew out hot liquid and minerals from deep inside the earth’s core. These chemicals mixed together creating the perfect soup that created the first single celled primitive life on earth.
For nearly 200 million years life on earth remains the same only single celled organisms. The planet spins more slowly and it has cooled down, life has started to evolve. In the shallows of the sea many round rocks are forming, but they are not rocks they are primitive plant like bacteria that are converting light and the Co2 in the ocean into oxygen and glucose, this is a process called photosynthesis. These bacteria expand and grow everywhere filling the oceans with huge amounts of oxygen. Oxygen combines with iron to form rust that falls to the ocean floor creating millions of very rich iron deposits that we will mine millions of years later. Two billion years later the planets spin has slowed to 16 hours a day, the days have become longer so the bacteria can pump out even more oxygen. Over the next million years the planet cracks and plates are created form the earths cores heat expanding and escaping. Earth’s plates move around carrying the islands and oceans with them, soon the all the masses of earth are collected in one place the super continent called Rodinia. On average the temperature is 85 degrees and the days 18 hours long, but there is still no life on land it looks more like mars then earth. This is because the suns high UV rays scorch the land so no life can exist on land.
Deep in the Earth’s core heat escapes and cracks the super continent in half and year over year the continent drifts apart. Volcanoes form on land and spew carbon dioxide into the atmosphere creating acid rain. Rocks on the surface start to absorbs the rain and the Co2 soon there is not enough carbon dioxide to keep the planet warm, in just a couple thousand years after the planet’s temperature plummets and its freezing. This is the start of a period called snowball earth the longest and coldest ice age ever to strike the earth. Massive sheets of ice spread across the earth thousands of feet tall. The ice moves rapidly and the more ice there is the more the suns heat and rays are deflected creating more ice and freezing the planet even more. Soon an ice sheet 10,000 feet thick cover the entire planet. Freezing temperatures and conditions last for 150 million years, but the core of the earth is still hot and it releases volcanoes to pump out Co2, without any rocks to absorb the gas it fills and covers the atmosphere. Our planet now has a blanket that starts trapping in more and more heat; the ice sheets have started to melt retreating back to the poles. Frozen ice is releasing oxygen and hydrogen peroxide formed from the ice and sun reacting. Air around the earth is now warm like a summer day and the days are 22 hours long. Along with all the oxygen and water it is the perfect recipe for life to thrive, but it is now where to be seen did every thing die out in the big freeze? To find life we have to look in the place where we first saw it, the ocean.
Those bacteria have been cling on to life and evolving, there are now lots of different plant species and some species of animals. Oxygen is plentiful, allowing creatures to grow bigger and have bony skeletons. There are what looks like an armored slug and other life. Such as worms, slugs, sponges trilobites and anomalocaris. Anomalocaris is a predator that hunts trilobites it is one of the first organisms that have eyes other than that it has razor sharp teeth and long grasping limbs on its face, the creature measures 2 feet long. Another amazing life form is the pikaia it is a primitive fish that has developed a long and hard backbone, a primitive vertebrae, this fish is the father of all animals and humans that have backbones. Beneath the waves there are tens of thousands of animal and plant species, the advance of life seems unstoppable. On the land however that earth is barren there is no critters or trees that populate the land only some algae why is that? It is because the sun’s deadly radiation is passing through the atmosphere and toasting the land, whether the life in the ocean is shielded by water. Up in the sky something is happening oxygen is combining with other elements and creating a gas called o-zone, it forms layers of blankets and blocks out the radiation. With out this layer life on land wouldn’t even exist and now that it’s there life has a rocket booster and it takes hold.
Mossy plants are the first life on land and that pumps even more oxygen into the air, next is trees and more complex plant life. Tiktaalik a strange fish is one of the first animals to climb onto land; it uses its fins as legs to support its self. Millions of years later the fins evolve into legs until it can leave the water completely. Creatures called tetrapods move onto land to eat the abundance of plant life on land. These tetrapods later evolve into, dinosaurs, birds and mammals. Plant life use to reproduce using spores, but now they have evolve seeds letting the trees spread their branches far and wide. Many insects are hundreds of times larger then what they are now; this is because of the high levels of oxygen in the atmosphere allowing the bugs to grow. Over the next millions of years animals evolve and adapt to their surroundings, evolving things like fur, wings, feet, shelled eggs and other evolutionally traits. The power of evolution helps the creatures stay alive through the earth’s many challenges and let mammals finally evolve into us.
The Earth has come a long way since being chunks of rock; it has evolved far and created many creatures along with us. Luck has played its part and help the perfect planet bring life on earth. Planet Earth has varied from being a flaming ball of fire to a ball of ice. We have uncovered the past and learned about how our planet was created and how unforgiving it can be. How the creatures cling on to survive through thick and thin. However the earth is still young there may be many other chapters and episodes of adventure in the near future. After all who knows how far evolution will take us.
