Some of the water molecules in your drinking glass were created more than 4.5
To understand how life emerged, scientists investigate the chemistry of carbon and water. In the case of water, they track the various forms, or isotopes, of its constituent hydrogen and oxygen atoms over the history of the universe, like a giant treasure hunt.
"This means that water in our solar system was formed long before the sun, planets, and comets formed," Merel van 't 'Hoff, a University of Michigan astronomer and co-author of the paper, says in the news release.
It indicates that water in our solar system formed billions of years before the Sun.
The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming.
Life on earth probably began in the depths of the ocean and not on the planet's surface, claim scientists.
Scientists have found water trapped in minerals deep within the Earth's mantle and crust, he explained. This water is even older than dinosaurs. It doesn't look like liquid water that's in your glass, but it still made of the same stuff.
The water on our Earth today is the same water that's been here for nearly 5 billion years. So far, we haven't managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
In Earth's Beginning
At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.
The origin of Earth's water has been an enduring mystery. There are different hypotheses and theories explaining how the water got here, and lots of evidence supporting them. But water is ubiquitous in protoplanetary disks, and water's origin may not be so mysterious after all.
It suggests that most of Earth's water was on the surface at that time, during the Archean Eon between 2.5 and 4 billion years ago, with much less in the mantle. The planet's surface may have been virtually completely covered by water, with no land masses at all.
Every living thing on Earth needs water to survive and the water that we drink today is the same water that wooly mammoths, dinosaurs, and the first humans ever drank! Earth only has a certain amount of water and it travels around moving between lakes, rivers, oceans, the atmosphere and the land.
One suggests that Earth's water might have been captured from asteroids and comets that collided with the planet. But recent research has strengthened the case for the other theory that water was always present in the rocks of the Earth's mantle and was gradually released to the surface through volcanoes.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.
Far from the Sun, where temperatures are low, water formed icy objects such as comets, while closer to the Sun water reacted with rocky materials to form hydrated minerals. It's thought that the mostly likely way that planet Earth inherited its water was from asteroids and comets crashing into it.
Before, when people lived as hunters/ collectors, river water was applied for drinking water purposes. When people permanently stayed in one place for a long period of time, this was usually near a river or lake. When there were no rivers or lakes in an area, people used groundwater for drinking water purposes.
Earth has vast oceans today, but our planet was a dry rock when it first formed — and water was a late addition, rained down in asteroids from the icy outer solar system.
Water, water everywhere—and not a drop to drink. In 1972, scientists were astonished to see pictures from NASA's Mariner 9 mission as it circled Mars from orbit. The photos revealed a landscape full of riverbeds—evidence that the planet once had plenty of liquid water, even though it's dry as a bone today.
Curious Minds further says that homosapiens have been around for only 200,000 years. So chances are that in every glass of water that you drink, there is some part of the water which has passed through a dinosaur at one point in time.
Floodplain dinosaurs slurped from local rivers, while forest dinosaurs drank water rich in minerals that had circulated through the rocks, picking up volcanic salts on the way.
Over millions of years, much of this water is recycled between the inner Earth, the oceans and rivers, and the atmosphere. This cycling process means that freshwater is constantly made available to Earth's surface where we all live.
Every glass of water contains almost 100% Jurassic pee, claim scientists. The next time you reach for a glass of water, remember this; you could be about to sip on dinosaur pee.
Life on Earth began in the water. So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment.
The water on Earth is the same water that has been here for almost five billion years, which means the water you're drinking, has been drunk around ten times before and even contains dinosaur urine.
