How old is the water on Earth?
3.8 billion yearsThere is also geological evidence that helps constrain the time frame for liquid water existing on Earth.
A sample of pillow basalt (a type of rock formed during an underwater eruption) was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago..
What happens to a glass of water if it is left out?
When you leave the glass of water uncovered for about 12 hours, carbon dioxide in the air starts to mix with it. This reduces the pH level of the water and gives it an off taste. But even then this water is safe to drink. Moreover, most experts believe that tap water has a shelf life of six months.
What killed of the dinosaurs?
The exact nature of this catastrophic event is still open to scientific debate. Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.
Why did T Rex have small arms?
The precise purpose of T. rex’s relatively tiny arms has long been mysterious. Over the years, scientists have suggested that they might have been used to grasp struggling prey, to help resting dinosaurs push themselves up from the ground, or to grip tight to mates during sex.
Was T Rex a plant eater?
rex and its carnivorous kind but, surprisingly, was a herbivore.
How long did the dinosaurs rule the world?
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Do Dinosaurs Eat?
Some dinosaurs ate lizards, turtles, eggs, or early mammals. Some hunted other dinosaurs or scavenged dead animals. Most, however, ate plants (but not grass, which hadn’t evolved yet).
How did at Rex sleep?
A sleeping T. rex likely settled down on its haunches, belly and chest flat to the ground, perhaps curled up to tuck its formidable muzzle against its side, with its tail wrapped around.
Is the water we drink older than the sun?
The sun, at 4.6 billion years old, predates all the other bodies in our solar system. But it turns out that much of the water we swim in and drink here on Earth is even older.
Would at Rex die if it fell over?
This impact alone could kill, says Farlow, and T. rex’s tiny front legs would have done nothing to break its fall. Further injuries would have been suffered as the beast slid on the ground, propelled by its forward momentum. Farlow says that a fall at any speed could have been lethal.
What did dinosaurs drink?
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.
Is new water ever created?
So, there’s lots of water being made every day. So, the water molecules that are here are not the same water molecules but the chemicals that they’re made from, the Earth is pretty much a closed system. We’re losing a bit of hydrogen off into space which is rearranging molecules to make new ones all the time.
How did at Rex mate?
The male bird has sex with the female by pressing his cloaca to hers in a “cloacal kiss”, thereby passing semen from his to her orifice.
Can water be created by man?
Answer 2: Yes, one can take Hydrogen and Oxygen and react them in appropriate conditions and form water vapor. This can then be condensed (by cooling) to liquid water. This is the best way to produce the most purified water that has no other ions that are normally present in water we know.
Did we drink the same water as the dinosaurs?
Because of the way this water cycle has always circulated our planet, there is indeed a chance that the water in your glass is the same water that thirsty dinosaurs were drinking about 65 million years ago.
Does rain water dinosaur pee?
Conjuring up prehistory, International Water Association Board Member, Daniel Nolasco, described this re-used water as “dinosaur pee”. Technically speaking, all water is re-used – that’s the nature of a closed hydrological cycle.
How long was a day 6 billion years ago?
According to it, the first evidence of life, 3.5 billion years ago, happened when the day lasted 12 hours. The emergence of photosynthesis, 2.5 billion years ago, happened when the day lasted 18 hours. 1.7 billion years ago the day was 21 hours long and the eukaryotic cells emerged.
How did dinosaurs drink water?
Dinosaurs knew about the water cycle, do you? They drank, swam and walked through water while it transformed between a liquid (water), gas (air), or solid (ice). You can thank the water cycle for changing dinosaur pee back into fresh water for us to use today!
