Pretty much, if we call "the beginning" the period after about 3.5 to 4 billion years ago when they Earth developed enough of an atmosphere to keep the bigger meteorites out. Scientists don't agree on where the water came from in the first place, but one theory is that it came from these meteorites and comets, and we still get just a little bit when small ones make it through the atmosphere. Either way, we have basically the same amount of water now as we did then due to the water cycle, meaning water is cycled through the atmosphere and earth systems without being created or destroyed.
What else can I help you with?
Is the water on earth the same as from the water years ago?
During global warming all of the water was frozen leading to not much water now that it got warmer (green house affect ) there is more water now than then written by a fifth grader
What can you infer from the fact that there is the same amount of water on the planet now as there was one billion years ago?
That the water cycle never stops working.
What can you infer from fact that there is the same amount of water on the planet now as there was one billion years ago?
That the water cycle never stops working.
Is there the same amount of water on Earth as when the dinosaurs were alive?
According to most scientists, we have had virtually the same amount of water on Earth since the planet formed. That would mean that there was the same amount of water on Earth when the dinosaurs existed. However, it is important to note that there is probably an infinitesimal amount more water now then there was in the time of the dinosaurs, simply because of the fact that there have been meteors/meteorites that carried a little bit of water to Earth since the dinosaurs died out.
Is cold water less dense that hot water?
As water eats up, it expands. There is still the same amount of water, but now in a larger space so it is less dense than cold water.
Why is hot water less dense that cold water?
As water eats up, it expands. There is still the same amount of water, but now in a larger space so it is less dense than cold water.
How much hay did horses consume during the US Civil War?
the same amount that it does now, so about 5 to 8 times a day if they were getting the proper amount of water.
Have bats changed over time?
no bats have not changed at all! They were the same from the beginning to now!
Why the ice have lower density or greater volume than water after freezing the same amount of water?
When you freeze water it expands, but does not gain mass, this means it's the same mass but now it is a higher volume. Density=mass over volume. More volume= less density.
What is the Lowest amount of money ever won on the game show Wheel of Fortune?
$1000 is the lowest amount a contestant can win on Wheel of Fortune. However it is a long running show that replaced a show with the same name that had daytime shows and the prizes in the beginning were much smaller than now. In the beginning of the daytime show the minimum dollar value on the wheel was $25
How do you make a 50 percent solution?
You take y liters of the solution and put it into a bucket or container. You then put y (same amount as before) liters of water in the same container, and voila! You now have a container with 50 percentile solution, 50 percentile water.
What can you infer from the fact that the same amount of water as there is now is the same amout one billion years ago?
The fact that the same amount of water exists now as it did one billion years ago suggests that Earth's water cycle is a closed system, where water is continually recycled through processes such as evaporation, condensation, and precipitation. This stability indicates that while water may change forms and locations, the overall volume remains constant over geological time. It also implies that the planet's climate and conditions have been conducive to maintaining liquid water, essential for life. This continuity underscores the importance of water in sustaining ecosystems throughout Earth's history.
