∙ 12y agoIn all likelihood, probably. The water cycle would make sure that all the water on the Earth would be used, evaporated, and then sent down into the Earth over time. The amounts of water may have changed slightly over time, but the relative amount of water hasn't changed much at all, just the water placement and it's distribution.

∙ 12y agoYes, the total amount of water on Earth remains relatively constant over long periods of time due to the water cycle. The Earth's water has been recycled and redistributed through processes like evaporation, precipitation, and runoff. So, the amount of water present now is likely similar to what was available during the time of the dinosaurs.
The inner planets do not have a significant amount of water on their surfaces. Earth is the only inner planet with substantial water, covering about 70% of its surface.
Earth is the planet that contains the most abundant amount of water, with about 71% of its surface covered in water. Other planets in our solar system, such as Mars and Venus, have negligible amounts of surface water in comparison.

because earth is the only planet which has water,75% of the earth is water but now i think they found out a new planet which also has water in it.
There is no exact number of water droplets that go around the water cycle as it is a continuous process where water evaporates, condenses, and precipitates. However, it is estimated that the same water molecules have been cycling through the Earth's water system for billions of years.
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.

Earth is known as the water planet because about 71% of its surface is covered by water, mostly in the form of oceans. Water plays a crucial role in supporting life on Earth, regulating the climate, and shaping the planet's physical features. This abundance of water distinguishes Earth from other planets in our solar system.

Europa and Titan have more water than is found on Earth.
Increase Due to melting polar caps

The amount of water on Earth remains relatively constant because of the water cycle. Water is continually cycling through processes like evaporation, condensation, and precipitation, which maintain a balance in the overall amount of water on the planet. Additionally, the Earth's gravity prevents water from escaping into space.

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.
