Answer

One example of evidence that supports the concept of crustal uplift is the presence of marine fossils found at high elevations in mountainous regions. Fossils of marine organisms, such as seashells and marine sediments, have been discovered at considerable heights above sea level, indicating that these regions were once underwater. The presence of marine fossils at elevated positions provides strong evidence of past crustal uplift, suggesting that these areas were once part of ancient sea floors and have been uplifted over time due to tectonic forces.
