To learn more, start your googling with these keywords:
Hypsometric Curve: Basically, a chart that shows the proportions of surface area at every elevation on a planet.
Crust: Earth's outermost layer, made out of two distinct materials – oceanic crust (which is denser) and continental crust (which is less dense).
Lithosphere: The rigid outer layer of Earth, including the crust and the hard, un-bending part of the upper mantle.
Subduction: The process of an ocean plate crashing into another plate and getting forced to dive down into Earth's mantle.
Isostasy: Describes the way earth's crust sort of floats in the underlying mantle. Continental crust is less dense and thicker, and floats higher than the oceanic crust, which is denser and thinner. Geologists talk about things like isostatic rebound, which is what happens after an ice age, when the ice melts off a continent and the continent lifts up, like a floating raft in a pool after someone gets off (though continents rise more slowly).

Naked Science - Birth of the Earth

Subscribe to Naked Science -

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

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.

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.

10 Places Science Can't Explain

Some of our planet's most mysterious places seem to defy the laws of science. Here are some of such.

The devil's kettle waterfall is believed by some to be a gateway to another universe or even to hell itself. The two streamed waterfall has baffled geologists for decades as no one can work out where the water flowing into the kettle leads. It's as if it simply disappears. But that's not the only mysterious water structure. In the amazon river is now known to be a boiling river hot enough to kill any creature to fall into it. It was thought nothing more than a myth until it's recent discovery and no one knows why the water is hot enough to boil.

In India stands a small village known for having a high twin rate. It's obvious why the settlement is now known as twin town but less obvious why so many twins are born here. Suggested answers include the claim that government experiments secretly changed the genetics of locals decades ago.

Perhaps the most mysterious location is the zone of silence in Mexico, a place known for magnetic phenomena and as a dead zone for radio. You will receive no radio signal while in the zone and don't expect your compass to be reliable. Also watch out for mutated animals or strange alien like figures - those are never a good sign.

Earth Science

... The American Geological Institute (AGI) is a nonprofit federation of 45 geoscientific and professional associations that represents more than 120,000 geologists, geophysicists, and other earth scientists.

Earth science (also known as geoscience, the geosciences or the Earth sciences), is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science, the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth science.

There are four major disciplines in earth sciences, namely geography, geology, geophysics and geodesy. These major disciplines use physics, chemistry, biology, chronology and mathematics to build a quantitative understanding of the principal areas or spheres of the Earth system.

The following fields of science are generally categorized within the geosciences:

- Geology describes the rocky parts of the Earth's crust (or lithosphere) and its historic development. Major subdisciplines are mineralogy and petrology, geochemistry, geomorphology, paleontology, stratigraphy, structural geology, engineering geology and sedimentology.

- Geophysics and Geodesy investigate the figure of the Earth, its reaction to forces and its magnetic and gravity fields. Geophysicists explore the Earth's core and mantle as well as the tectonic and seismic activity of the lithosphere.

- Soil science covers the outermost layer of the Earth's crust that is subject to soil formation processes (or pedosphere). Major subdisciplines include edaphology and pedology.

- Oceanography and hydrology (includes limnology) describe the marine and freshwater domains of the watery parts of the Earth (or hydrosphere). Major subdisciplines include hydrogeology and physical, chemical, and biological oceanography.

- Glaciology covers the icy parts of the Earth (or cryosphere).

- Atmospheric sciences cover the gaseous parts of the Earth (or atmosphere) between the surface and the exosphere (about 1000 km). Major subdisciplines are meteorology, climatology, atmospheric chemistry and atmospheric physics.

- A very important linking sphere is the biosphere, the study of which is biology. The biosphere consists of all forms of life, from single-celled organisms to pine trees to people. The interactions of Earth's other spheres - lithosphere/geosphere, hydrosphere, atmosphere and/or cryosphere and pedosphere - create the conditions that can support life.

2018-ல் பூமிக்கு வரும் பேரழிவு 1500 விஞ்சானிகள் எச்சரிக்கை | Earth Science | Tamil Mithran

2018-ல் பூமிக்கு வரும் பேரழிவு 1500 விஞ்சானிகள் எச்சரிக்கை | Earth Science | Tamil Mithran
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.[24][25][26] 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.[27] The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earth's orientation on its axis, and gradually slows its rotation.[28] 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.[30][31] 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.

The Science of Flat Earth

For thousands of years, ancient cultures everywhere knew the earth was a flat, motionless plane in the center of the universe based off the observations of the true world around them. For instance, the stars of the heavens appear to be revolving above our heads and water is always flat, so the oceans must be flat, and the stars must revolve around us like our God-given senses indicate. Our ancestors observed the world and based their conclusions off what they were seeing, but then something changed.

Psychopaths began to gain power and control over science and changed our reality from observing the world through the scientific method to a faith-based religion entirely dependent on the system. Through brainwashing institutions like School, subjecting innocent children to blindly accept fallacies as truth, through televisions and TV programming showing Freemasons landing on the moon, these powerful psychopaths with bloodlines handed down through the ages have removed mankind from the center of the universe disregarding our own human senses as the true reality of the world we live upon. They have removed God from the picture, placing humans as the accidental coincidence and product of evolution from monkeys with no purpose in our lives, disconnecting us from our divine origins of intelligent design.

We are convinced through lying manipulators that our ancestors were stupid and just didn’t know what we know today. The truth is however, we create the very realities of our human existence. The Earth is flat. We have been lied to and we have been enslaved. From birth we are taught to mock and ridicule the very idea of earth being the flat center of our universe like our eyes clearly show us, but instead take the gospel of Neil DeGrasse Tyson and Bill Nye as the ultimate truth that we are meaningless apes created by accident. I beg to differ. I was once a believer in the heliocentric ball-earth religion, but then I was ridiculed for questioning it just as many others have been. Slaves think they’re smart because they take the word of liars who clearly manipulate them. The fact of the matter is however, real science supports the flat, motionless earth while false, unprovable pseudo-science has enslaved humanity on a ball. There are many scientific proofs of the flat earth.
