2. The Himalayas in central Asia are the tallest mountains in the world. But fossils of seashellis can be found high in these mountains, far from any ocean. How do you think they got there?

The Himalayas were formed through the collision of the Indian and Eurasian tectonic plates, a geological event that began around 50 million years ago. Before that collision, the region was submerged under an ancient ocean called the Tethys Sea. As the plates pushed upward, these marine sediments were uplifted to form the peaks we see today, which explains the presence of seashell fossils high in the mountains. Fossils of seashells in the Himalayas offer a fascinating glimpse into the Earth's dynamic history. These remnants serve as crucial evidence for paleontologists, suggesting the area was once a vibrant marine environment. Studying these fossils not only helps reconstruct ancient climates but also aids in understanding the processes of plate tectonics and how life adapts to changing geological landscapes.
