Water is continuously replenished. Same water exists as it did earlier.
It's hard to beleive, but exactly the same water as now.
water is neither destroyed nor created, it is only transferred so yes.
yes it is possible because of the water cycle. water that was in the lake then, went into the sky, the stuff in the sky condenses then precipitation happens, and then eventually that water evaporates. and so it continues.
This animal is not adaptted to salt water.
There is no effect.
No, they do not swim. Hadrosaurs (duckbilled dinosaurs) are the only ones that swim. Imagine that...a hadrosaur!
The Water When The Dinosaurs Lived Is The Same As The Water We Drink today.But We Make Changes To The Water,Even If We Do It Will Be The Same Water As The Dinosaurs Drank(Get It?)
It is possible that many dinosaurs were able to swim. I´m sure the hadrosaurs (duck-billed dinosaurs) were capable of doing just that. However there weren't any that were built like seals or dolphins. Animals such as the icthyosaurs, plesiosaurs, and pliosaurs were all reptiles and not dinosaurs. Like most large land animals today, most dinosaurs could probably swim, if only marginally. No known dinosaur has been found that actually lives in the water, though some evidently ate fish and lived near water.
Dinosaurs never flew dinosaurs were land reptiles although some dinosaurs could swim
No dinosaurs specifically lived in the water. Plesiosaurs, pliosaurs, mosasaurs and ichthyosaurs lived in the water (but are not DINOSAURS). They are reptiles but not dinosaurs. They co-inhabited the planet with dinosaurs, in the same way that the pterosaurs ruled the air. Pterosaurs were not dinosaurs either.

In deep water
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.
It's hard to beleive, but exactly the same water as now.
You mean Plesiosaurus? Oh, nope, it's not a dinosaur at all, no dinosaurs back then could swim...or fly. "Flying Dinosaurs" are actually a different group of prehistoric reptiles. Same goes for "Swimming Dinosaurs."
the same amount of water we have today... (70%)
None! Dinos didn't fly or swim.
