Fish fossils have been found in some places where there is no longer any water. Sometimes, they are found on top of mountains. What is the BEST explanation for why the fish fossils were found in places with no water?

The best explanation for why fish fossils were found in places with no water is that these areas were once underwater millions of years ago. Over time, geological processes such as tectonic plate movements, erosion, and land uplift have transformed these areas into their current state, leaving behind the remains of ancient marine life. This indicates that the environment in these areas has changed significantly over time.
