How did the Earth evolve to support life.

Our planet now supports a huge diversity of living creatures requiring very special conditions, but what was the series of events that brought this unique set of conditions together? What did it take to make a world that would support human life? Naked Science takes an imaginary ‘human’ time traveller on a journey back to the moment of formation of our solar system. We meet the scientists who are carrying out their own detective work, uncovering the clues around the world today into what our planet was like 4 and a half billion years ago.

Our journey begins with the astonishing story of how a giant cloud of interstellar dust and gas collapsed to form the sun and planets. We discover that the intense heat of the early Earth created a molten iron core. This generated a magnetic shield around our planet that protects us, to this day, from the sun’s deadliest particles.

Many of the features we take for granted on our living planet were forged in the most violent event in our planet’s history. Early in its life, the Earth collided with another planet. Planetary Scientist Robin Canup has modelled the impact using supercomputers. She reveals that the resulting fireball was so energetic it melted the Earth and created the moon. This dramatic impact gave us our tides and seasons.

We wouldn’t have life today without water. But where our water came from is a mystery that has long puzzled scientists. At a NASA research laboratory, Michael Zolensky studies a recently discovered meteorite that supports the view that water came from space.

For the first half of its history the Earth had an atmosphere of methane and carbon dioxide we would find impossible to breathe. One clue as to how the earth acquired its oxygen can be found in Australia. Shark Bay in Western Australia is home to strange bacterial mounds called stromatolites. The bacteria in these objects are pumping out oxygen. A few hundred miles away geologist Martin Van Kranendonk shows us a fossil stromatolite, the world’s oldest fossil. The evidence suggests that these strange objects are responsible for creating the air we breathe.

Where does a cup of coffee come from? In this film, it’s not Starbucks, it’s stars busting. We go right back to the beginning of time to show where the ingredients in your cup of coffee were born.

The main ingredient is hydrogen; it makes up most of the water in your cup. And that formed in the big bang. How it got from there, into your cappuccino is one of the most dramatic stories in science. It has taken thousands of scientists to track its trail. We follow it through stars and galaxies, exploding supernovae, and giant clouds of gas to show just how it reached your cup.

But that isn’t the end of the story. For where it goes in the future, depends on the fate of the universe. Will it carry on expanding for ever, or tear itself apart?

The History of Earth - How Our Planet Formed - Full Documentary HD

In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.

It is theorized that the true age of the earth is about 4.6 billion years old, formed at about the same time as the rest of our solar system. The oldest rocks geologists have been able to find are 3.9 billion years old. Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in - when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock - a magma ocean.

Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Due to the forces of plate tectonics, our planet is also a very dynamic one; new mountains forming, old ones wearing down, volcanoes melting and reshaping new crust. The continual changing and reshaping of the earth's surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. So the age is a theoretical age.

When Did Life on Earth Begin?

Scientists are still trying to unravel one of the greatest mysteries of earth: When did life first appear and how did it happen? It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. Some crawled from the seas and took residence on land, perhaps to escape predators in the ocean. A cascading chain of new and increasingly differentiated forms of life appeared all over the planet, only to be virtually annihilated by an unexplained mass extinction. It would be the first of several mass extinctions in Earth's history.

Scientists have been looking increasingly to space to explain these mass extinctions that have been happening almost like clockwork since the beginning of living time. Perhaps we've been getting periodically belted by more space rocks (ie. asteroids), or the collision of neutron stars happening too close for comfort? Each time a mass extinction occurred, life found a way to come back from the brink. Life has tenaciously clung to this small blue planet for the last three billion years. Scientists are finding new cues as to how life first began on earth in some really interesting places - the deep ocean.

Naked Science - Colliding Continents

Subscribe to Naked Science -

How were the continents formed?

We walk over them without a second thought, but where did the land beneath our feet come from? We go back in time to the oldest rocks on earth, to see how the first continents formed on our fledgling planet. We see how continents are just lighter rocks, floating on a layer of denser molten rock, the mantle.

Travelling to the bottom of the Grand Canyon we follow the process of erosion and sedimentation that created the landscape we see today. At the Giant’s Causeway, in Ireland, we tell the story of how a continent split into two, creating America and Europe, and in the Himalayas, we see how two continents colliding create the tallest mountains on earth.

But what of the future? Using computer simulations, we trace the progress of the continents over the next 250 million years and discover that they will all merge into one.

There is a place on Earth that we have never seen. It is a place of unimaginable heat and pressure, where no life could survive. Yet without it, we would perish for it holds the key to our precarious existence on this planet.

2000 miles below the Earth's surface, there is a vast ocean of molten iron. The spinning outer core of the Earth generates a protective magnetic shield around the planet, defending life from lethal space radiation. But now there is startling data that it could be about to stop defending us. Naked Science is taking you on a journey to the centre of the Earth.

Naked Science - Moon Mysteries

Every other Wednesday we present a new video, so join us to see the truth laid bare...

The moon is far more than just a beautiful object in the night sky.

Ever since its creation 4.5 billion years ago the moon has been edging away from Earth into space. Throughout its journey, it has influenced our planet in different ways. But one things clear, without it life would never have emerged on Earth.

4.5 billion years ago the moon forms when another planet slams into the early Earth. The impact knocks our planet “off-balance” onto an axis of 23 degrees, which we still rotate around today. This is what gives us our seasons. Without it we would have no summers, springs, winters or falls.

4 billion years ago the solar system endures the most violent meteorite bombardment in its history, the Lunar Cataclysm. The Earth, being 50 times bigger than the moon, exerts a massive gravitational pull on incoming space debris. Because the moon is still so close to Earth it too gets hit. 99% of all craters on the lunar surface visible today are a result of this bombardment.

3 billion years ago the Earth has water and oceans. Because the moon is far closer its gravitational pull is far stronger on the Earth. The tides it creates are thousands of feet high and smash hundreds of miles inland every day. Scientists believe that these tides feed the Primordial Soup with the minerals required to start life. Without them only the most basic microbes would be on Earth today.

Today the moon has the same gravitational pull as a mosquito landing on your head, yet some people still believe it can influence our planet in bizarre ways.

The San Francisco Police Department tell us how crime appears to soar during a full moon. But the scientific data suggests otherwise, studies show no correlation between the Full Moon and violence. Naked Science investigates.

Scientific research into the moon is allowing some scientists to predict when natural disasters will strike. Some researchers believe that when the sun and moon align and pull together on the Earth they can trigger both earthquakes and volcanic eruptions.

In the future the moon will move so far from Earth that it will affect the fine balance of our planet, sending our climate tumbling out of control.

Secrets Of Earth: Hindi Documentary

Secrets Of Earth : Hindi Documentary

Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.[n 5]

Earth's axis of rotation is tilted, producing seasonal variations on the planet's surface. The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest of the four terrestrial planets.

Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by oceans.[29] The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the Earth's magnetic field, and a convecting mantle that drives plate tectonics.

Within the first billion years of Earth's history, life appeared in the oceans and began to affect the Earth's atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Some geological evidence indicates that life may have arisen as much as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive. In the history of the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of all species[32] that ever lived on Earth are extinct.[33][34] Estimates of the number of species on Earth today vary widely;[35][36][37] most species have not been described.[38] Over 7.4 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans have developed diverse societies and cultures; politically, the world has about 200 sovereign states.

Harbingers of doom or givers of life?

Comets, distant travellers from the outer reaches of our solar system, have captured the imagination of man and have long been shrouded in mystery. Now through Earth based observations and an increasing number of space probes, their origins and nature are becoming unveiled. Naked Science explores behind the legend to reveal what a comet actually is, what secrets they hold for our understanding of how the solar system was formed; shed light on the theory that they brought the building blocks of life to earth and their potential for wiping out life as we know it.

Naked Science - Alien Contact

Subscribe to Naked Science -

Every other Wednesday we present a new video, so join us to see the truth laid bare...

Just for a moment, imagine a universe awash with life, where we humans are not the only intelligent beings around. What might these alien races look like? Could we communicate with them, or even recognise them as intelligent? And what would they make of our violent and dangerous species? Might they take one look, and decide not to bother with such primitive beings? A planetary nursery filled with spiteful, galactic infants. On the other hand, in our imaginary scenario, they may enrich us with scientific knowledge beyond our imagination. Or could an encounter with aliens have a more destructive outcome? It could be a bad day for human kind. But relax, it’s just make believe, it could never happen, could it?

A mysterious crash in Roswell, New Mexico during the 1940s convinced many that our planet is being visited by space aliens. Crop circles in Britain have only added fuel to the fire. Few scientists doubt that life indeed exists elsewhere, but some believe we're more likely to make contact via radio waves. Join the search for extra-terrestrials and hear from scientists who think we are on the verge of making contact.
