Puerto Rico Trench: Marine Life and Geography

Puerto Rico, a small island, boasts a unique geography with mountains, rainforests, deserts, and more. The Puerto Rico Trench, the deepest in the Caribbean and Atlantic, is notable for its gravity anomaly and rich biodiversity. It supports diverse marine life and ecosystems, including hydrothermal vents. However, its location as a subduction zone poses seismic risks, leading to earthquakes and tsunamis. The video encourages viewer interaction and sharing.
