Why is Earth the only planet with water?
In our solar system, Earth orbits around the sun in an area called the habitable zone.
The temperature, along with an ample amount of atmospheric pressure within this zone, allows water to be liquid for long periods of time.
Evidence points to water on other planets in our solar system..
Are giraffes dinosaurs?
No. Brachiosaurus was a dinosaur that lived around 150 million years ago. By the time that Brachiosaurus became extinct, there were already early mammals called Eutheria living alongside the dinosaurs. The Eutheria gave rise to the placental mammals and then the Artiodactyla and, eventually, the modern giraffe.
How long is fresh water left?
A full 16 years ago, in 2001, the UN Population Fund warned that the world will begin to run out of fresh water by 2050, and UNFPA’s World Population Report from 1992 also warns of water shortages by 2050.
Do 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.
Is there pee in the water we drink?
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.
Why is water wet?
“Water is wet because when something is wet, it has water on it and on a molecular level, water molecules are bonded on top of each other, therefore water is wet.” An extension to the previous argument that a couple of students brought up was that one water molecule alone is not wet, but when water molecules touch each …
Who created water on Earth?
For decades, scientists have said that at least some of Earth’s water came from comets and asteroids. New research suggests an even more primordial source, the vast cloud in space from which our world formed. Earth, the water planet. Image via NASA.
Can water be created?
In theory, it should be easy to make water. It’s just two hydrogen atoms and an oxygen atom thrown together; how hard can it be? The answer: very. Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy.
Is it possible to drink the same water twice?
Short answer: For any given water molecule, the odds are basically negligible. But the odds that you’ve drank at least one water molecule twice are pretty much 100%. … Turns out this number is basically equal to 1, so the odds are almost certain that any two glasses of water will have at least one atom in common.
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!
How old is the water that we drink?
Yes. The water on our Earth today is the same water that’s been here for nearly 5 billion years. Only a tiny bit of it has escaped out into space.
Did dinosaurs pee?
To get this out of the way: yes, dinosaurs apparently did urinate. For years, scientists figured that dinosaurs, like most of their avian descendants, evacuated liquid and solid waste in a single stream from an orifice called the cloaca.
